The 2017 Atlantic usercane season was a below average season overall, but featured a record number of named userstorms forming, although most of the storms were weak, with only 4 usercanes - the least since 2012.

A usercane is a hypothetical tropical or subtropical cyclone that is assigned to a user once they reach 25 edits or more. On average, about 10 to 15 storms develop each season, albeit the last two seasons have seen over 30 named storms. Multiple usercane centers monitor usercane formation throughout the year, including the National Usercane Center, the Sass Master Weather Center, the Floyd Meteorological Center, the HTs Meteorological Center (HTMC) and the International Coriolis Observatory of the North Atlantic.

Although the season had an early start and featured a very high number of named storms, the season was very weak, and had the slowest start since 2013, with only 2 storms forming before the month of April. Despite the uptick in named storms in early June, only two achieved major usercane intensity — Usercane Chap, and Usercane Alissa - with the latter only achieving usercane intensity for a short time. The lack of activity is believed to be attributed to a significant weakening of the userthermohaline circulation, creating unfavorable conditions in the Atlantic — especially the Main Development Region (MDR). As of August, no usercanes have formed from tropical userwaves — the first such occurrence on record. In September, specifically late September, there was an explosive increase in activity, at least eight userstorms forming in late September alone. However, the season remains weak with no new usercanes. The explosion of activity continued on in October, even setting the record for the most named storms in any usercane season.

The season's strongest storm in terms of sustained wind speeds was Usercane Chap, a strong but compact Category 4 usercane. The season's largest and most intense storm, Usercane Cooper, was first of the other two fully tropical major usercanes, as Usercane Alissa remained a subtropical cyclone for its existence. The season also featured Usercane Prism, which reached Category 3 strength in the central Atlantic.

During post-season analysis, 6 unnoticed userstorms were identified — Tropical Userstorm Justin, Tropical Userstorm Barney, Tropical Userstorm Nicholas, Tropical Userstorm Orange, Tropical Userstorm Nibiru, as well as an unnoticed tropical userpression.

Ahead of and during the season, several usercane centers release seasonal forecasts. On December 4, 2016, the Garfield International Hurricane Center (GIHC) released its forecast, predicting above-average activity with 25 named storms, 7 usercanes and 5 major usercanes, which is slightly above the long-term average but significantly less active than the 2015 and 2016 seasons. On December 14, the National Usercane Center released their first 2017 forecast, predicting above-average activity with 25-30 named storms, 7-10 usercanes, and 5-8 major usercanes. A third hurricane center, the Akio Hypothetical Usercane Center (AHUC), made its prediction on December 23, 2016, predicting well above average activity with 34-38 Tropical Storms, 9-13 usercanes, and 7-11 Major usercanes. On the same day as the AHUC, the Floyd Meteorological Center (FMC) released their 2017 forecasts, predicting slightly above-average activity with 26-31 named storms, 7-10 usercanes and 4-7 major usercanes. The same day, the Brick National Meteorological Agency issued their forecast, predicting above-average activity, with 27-36 named storms, with 6-11 of those becoming usercanes (74 mph+), and 5-8 major usercanes (111 mph+). On December 26, 2016, ICON released its official prediction of 28 named storms, 11 usercanes, and 8 major usercanes for the 2017 season. That same day, the Keranique Meteorological Center (KMC) released their forecast, predicting an overall above-average season with 25 named storms, 11 usercanes, but a below-average 4 major usercanes. Also on that same day, the Money Hurricane National Hypothetical Hurricanes Center (MHNHHC) released their forecast, also predicting above-average activity but a less active season than 2015 and 2016, with 21 named storms, 11 usercanes and 5 major usercanes. On December 30, the HTs Meteorological Center (HTMC) released its forecast, predicting above-average activity as well with 27 named storms, 14 usercanes and 6 major usercanes. On December 31, the Mushroom Kingdom National Hurricane Center (MKNHC) released its seasonal prediction for 2017, predicting above-average activity with 29 named storms, 16 usercanes and 8 major usercanes. On January 6, the BPWPC made its prediction for the 2017 usercane season, predicting 26-31 storms, 10-12 hurricanes, and 4-8 major hurricanes, an above-average season. Later the same day, the Minecraft Hurricane Center (MHC) released its forecast for the season, predicting above-average activity, with 25 named storms, 11 usercane, and 5 major usercanes. On April 29, 2017, the BPWPC made its updated forecast, taking actual storms into account. It predicted 12-19 named storms, 3-8 usercanes, and 0-4 major usercanes. On June 27, the Mushroom Kingdom National Hurricane Center released its forecast, significantly lower then previous predictions - only predicting 11 named storms, 4 usercanes and only 1 major usercane. This was due to to the observation of a significant decrease in the strength of the userthermohaline circulation, creating conditions in the Atlantic similar to what is observed in the spring.

Season Summary

There were also several non-major hurricanes as well as tropical storms.

Tropical Storm Nicole 2016-10-04 1705z

Tropical Userstorm Chap on late-January.

January

Like 2016, it has an early start, Tropical Userstorm Chaser formed on January 6, six days after the season began. It didn't get past 40 mph, attaining pressure of 1006 mbar. However, on January 22, Chaser did degenerate into a remnant low. Usercane Chap also formed, it did a good, organized structure causing it to strengthen in the following month. Tropical Userstorm Mli also formed near Cape Verde, but struggled to strengthen due to shear later.

February

No storms formed in this month, but some changes in userstorm strength were observed. Only known change is observed, and that is Chap strengthened into the first usercane of the season.

March

No storms formed in this month, and no changes happened.

April

Karl 2016-09-23 1715Z

Tropical Userstorm Joshua at peak intensity.

After the last two inactive months, four storms formed in this month: Joshua, Koliana, Six and Brave. Tropical Userstorm Joshua came from a tropical userwave near Africa, and strengthened into a userstorm. Tropical Userstorm Koliana formed in a more favorable environment, though it didn't reach past 65 mph winds. Tropical Userpression Six formed but didn't get past userpression status. Subtropical Userpression Brave did have some tropical characteristics, though didn't manage to go full tropical. Tropical Userstorm Chaser did regenerate only for short amount of time, and turned into remnant low.

May

Usercane Chap attained category 2 status on mid-May. Several new storms formed, Tropical Storm Bin formed, from a userwave and strengthened into tropical storm status. Bin did some strengthening, but hasn't reached past userstorm status. Subtropical Userstorm Peri also formed, associated with intensifying Usercane Chap. It formed as weak and disorganized low, and weakened afterwards. It soon restrengthened into subtropical storm months later. Tropical Userstorm Carmen also formed from a tropical userwave, and peaked as weak userstorm, and didn't intensified further.

June

Lisa 2016-09-19 1505Z

Tropical Userstorm Addict after a week of formation.

There are two userstorms which formed in this month, namely Abdullah and Addict. Tropical Userstorm Abdullah formed in early 2017 as a wave, but didn't form until June. It forms and strengthened as tropical storm. Tropical Userstorm Addict formed in this month too, and peaked as severe tropical userstorm. It didn't have a much better convection.

July

Like June, it had two userstorms too. At this point, Usercane Chap strengthened into the first major usercane of the season. Those two userstorms are Tropical Userstorm Stacy, and Tropical Userstorm Minus. Tropical Userstorm Stacy formed on late-July, but it didn't last long soon and only regenerated in late August. Tropical Userstorm Minus didn't last too, as it formed as low, strengthened but eventually made landfall in North Carolina.

August

Usercane Cooper Jan 2018

Usercane Cooper in January 2018.

This month also featured two storms: Usercane Cooper and Tropical Userstorm Cake. Usercane Cooper formed from the interaction between a tropical userwave and an upper-level trough, and had abundant convection when it formed. Tropical Userstorm Cake didn't have that much convection, but still managed to reach tropical storm status.

September

This month was extremely active, with eleven userstorms forming. Two of those are usercanes (one subtropical) named Prism and Alissa, and the rest are userstorms and userpressions, namely Dene, Dezcrafter, Nineteen, Twenty-Seven, Astro, Manatee, Marie, Nova, Philippines and Ivy.

Tropical Userstorm Dene formed as regeneration of Tropical Userstorm Butter, did strengthen as userstorm, before making landfall a month later. Tropical Userstorm Dezcrafter formed as a userwave too, and strengthened into a tropical storm, before making landfall on November. Tropical Userpression Nineteen formed only and only lasted for one day, and it dissipated. Tropical Userstorm Ivy formed as userstorm and it lasted for about a month before turning into a remnant low.

UsercaneAlissa

Subtropical Userstorm Alissa at peak intensity.

Tropical Userstorm Manatee formed from a cluster of thunderstorms that spawned a lot of other userstorms too, and like others, it didn't last that long. Usercane Prism formed from upper-level through, it have a good convection enough to strengthen into a category two usercane. Tropical Userstorm Astro formed as well, it did stalled for months and didn't get past 50 mph. Tropical Userstorm Philippines is spawned from a upper-level through, believed to be regeneration of some kind of usercane years ago. It did some strengthening but weakened afterwards.

Subtropical Userstorm Alissa had an extremely weird orgin and structure. It came from a tropical low that exists on December 2016, and it had some tropical characteristics. It gathered energy in Gulf of Mexico and peaked as Category 3 with subtropical structure. It continues to thrive in the Gulf and it weakened into a severe subtropical storm, and later it degenerated. Tropical Userstorm Marie formed as well, it peaked into tropical userstorm status. Severe Tropical Userstorm Nova is currently active storm with good structure and came from a tropical wave. Tropical Userpression Twenty-Seven formed as well, but degenerated a month later.

October

Irma 2017-08-31 1515Z

Tropical Userstorm Harvey expanding.

This month was extremely active as well, though no usercanes formed and the strongest system was Tropical Userstorm Harvey. It is one of the userstorms that featured an eye and huge in size. Tropical Userstorm Fargoniac forms from a userwave, it didn't strengthen much and it degenerated months later. Tropical Userstorm Willman peaked as severe tropical userstorm, but it didn't have much convection and apparently it loses on the following months. Tropical Userstorm Olo is another userstorm which formed near Cape Verde, and it didn't strengthened as much.

Tropical Userstorm Fester is the userstorm with most landfalls, it formed from a tropical wave but it made landfall sooner in Europe. Fester then continues to spawn more userwaves but most of them did just end at making landfall. Tropical Userstorm Justin is another userstorm in this month, but didn't strengthen much until following months. Tropical Userstorm Orange is a userstorm that forms as userwave and it didn't strengthen that much. Tropical Userstorm Migs (previously named Pupper) is a currently active storm that is mostly normal but not that strong in structure. Tropical Userstorm Barg formed in mid-October and it only lasts for one month. Tropical Userstorm LOL is the last storm in the month, but it didn't last that long.

Storms

Tropical Userstorm Chaser (TornadoChaser100)

Tropical userstorm (NUC)
Tropical storm (SSHWS)
Lorenzo Oct 21 2013 1655Z.jpg Chaser Track.png
Duration January 6 – April 27
Peak intensity 40 mph (65 km/h) (1-min)  1006 mbar (hPa)
Around 14:00 UTC on December 31, satellite imagery indicated that a tropical disturbance had developed over central Africa. While gradually moving to the west, the wave originally showed very little convective organization, with sparse thunderstorm activity. On January 3, it entered the Atlantic Ocean and began to quickly develop, but the circulation remained ill-defined. The disturbance was designated Invest 90U by the National Usercane Center on January 4. Organization continued to increase over the next 2 days, and at approximately 15:00 UTC on January 6, Invest 90U became Tropical Userpression One as it developed a closed circulation. The userpression eventually strengthened into a deep userpression. However, it peaked just under tropical userstorm force, with a maximum wind of 38 mph reported. Convection eventually collapsed, and the userpression opened up into a tropical wave while located southwest of Cape Verde on January 22. On April 9, 2017, however, the wave developed a new circulation as winds had increased to tropical storm force, and the system was named Tropical Userstorm Chaser at that time. However, after briefly attaining tropical userstorm status, Chaser began to lose tropical characteristics once again as convection began to wane, and the low was no longer recognizable by late April.

Usercane Chap (TropicalStormChapsteck, formerly Chapsteck4yurlipis)

Category 4 usercane (NUC)
Category 4 hurricane (SSHWS)
UsercaneChap.png Chap 2017 Track.png
Duration January 18 – Active
Peak intensity 140 mph (220 km/h) (1-min)  943 mbar (hPa)
Main article: Usercane Chap

On January 18, a non-tropical area of low pressure developed along a stationary front south of Bermuda. The low separated from the front, eventually consolidating into Tropical Userstorm Chap. Nearly stationary, Chap slowly strengthened, acquiring severe tropical userstorm status by January 28. Chap continued to strengthen slowly. On February 23, 2017, Chap strengthened into the first usercane of the 2017 season. It intensified to 90 mph, but increasing wind shear caused Chap to remain weak through the next few months. Chap briefly weakened to 85 mph. Wind shear slowly abated in late April, and Chap's eye began to clear out, and on May 16, 2017, Chap attained category 2 intensity. On July 4, 2017, Chap became the first major usercane of the season. The storm intensified further and reached Category 4 strength on September 19.

After maintaning intensity as a Category 4 hurricane, Chap weakened slightly and then began to maintain its intensity. On April 16, 2018, Chap transitioned to a very strong subtropical cyclone.

Tropical Userstorm Mli (Mli048)

Tropical userstorm (NUC)
Tropical storm (SSHWS)
Fiona 2016-08-18 1605z.png Mli track.png
Duration January 26 – February 15
Peak intensity 50 mph (85 km/h) (1-min)  1004 mbar (hPa)
A non-tropical low located well east of Bermuda became a tropical userpression on January 26 after it developed persistent deep convection for several days. The userpession steadily strengthened into Tropical Storm Mli by January 31. However, deep convection dissipated on February 15 and the cyclone degenerated into a swirl of low-level clouds; Mli was no longer a tropical cyclone after this time.

Tropical Userstorm Joshua (Joshua Crain)

Tropical userstorm (NUC)
Tropical storm (SSHWS)
Karl 2016-09-23 1715Z.png
Duration April 1, 2017 – April 18, 2018
Peak intensity 50 mph (85 km/h) (1-min)  990 mbar (hPa)
On March 31, a tropical userwave exited the coast of Africa. Rapid organization occured with this wave, and the following day it was classified as a tropical userpression while located just 5 miles off the African coast, ending a 2 month period in which no tropical userpressions developed. By April 3, the userpression was producing winds of tropical userstorm-force, and the NUC upgraded it to Tropical Userstorm Joshua. Steady intensification occured throughout the remainder of the year. In its advisories on Joshua, the NUC noted the unusual persistence of the storm, which despite being forecasted to strengthen remained below usercane intensity. Eventually, Joshua began to succumb to the effects of westerly wind shear and increasingly colder ocean temperatures. After spending over a year as a tropical userstorm, Joshua finally transitioned to a post-tropical cyclone on April 18, 2018.

Severe Tropical Userstorm Koliana (Koliana67ana)

Tropical userstorm (NUC)
Tropical storm (SSHWS)
Koliana 2017.png
Duration April 8 – January 4
Peak intensity 60 mph (95 km/h) (1-min)  998 mbar (hPa)
A non-tropical low developed into Tropical Userpression Five late on April 8 in the central Atlantic Ocean. Early on April 10, the userpression strengthened into Tropical Userstorm Koliana. The quickly developing cyclone strengthened slightly before its intensity reached a stable point on April 20. After weakening slightly in early May, Koliana restrengthened to attain peak winds of 60 mph (95 km/h) and a minimum pressure of 998 hectopascals. Afterward, the storm slowly began to degrade in structure as it weakened. Kolina weakened rather slowly and at periods fluctuated in intensity. By January 4, 2018, Koliana became devoid of convection and degenerated to a non-convective extratropical low.

Tropical Userpression Six (79344a)

Tropical userpression (NUC)
Tropical depression (SSHWS)
Tropical Low Gabrielle Flipped.jpg
Duration April 23 – April 30
Peak intensity 25 mph (35 km/h) (1-min)  1010 mbar (hPa)

A low pressure area developed over the central Atlantic on April 2. Very gradual strengthening occurred over the next three weeks as convection developed and dissipated periodically. The low finally attained tropical userpression status on April 23, becoming the sixth tropical cyclone of the season. Shortly after, it began weakening and became a remnant low on April 30.

Subtropical Userstorm Brave (SmilingBrave)

Subtropical userstorm (NUC)
Subtropical storm (SSHWS)
60W 2006-11-07 2310z.jpg
Duration April 5 – August 15
Peak intensity 45 mph (75 km/h) (1-min)  1003 mbar (hPa)

In mid-March, an extratropical low formed along a frontal boundary. The low detached from the front and acquired some tropical characteristics in early April. On April 4, convection in the core of the system was well-defined, but the strongest winds remained far from the center of the low. Thus, the low was classified as Subtropical Userpression Seven on April 5. The NUC forecasted the system to quickly turn post-tropical, but instead it intensified slowly, becoming Subtropical Userstorm Brave on May 3. Brave remained steady in intensity throughout the following weeks. In early August, Brave abruptly lost nearly all of its convection, and days later was declared post-tropical.

Duration May 25 – November 13
Peak intensity 50 mph (85 km/h) (1-min)  993 mbar (hPa)

On May 25, a non-tropical low developed into Subtropical Userpression Nine in the central Atlantic. The userpression was initially weak and disorganized, and did not strengthen. On July 12, the NUC declared it a remnant low. Unexpectedly, showers and thunderstorms developed far from the center of the low the following day, although the remnants changed little in organization for the next two weeks. In late July, convection quickly reorganized, and after ASCAT data showed tropical storm force winds and a well-defined circulation, NUC initiated advisories on Subtropical Userstorm Peri on July 28. Peri's overall appearance improved as the storm intensifed. Unusually, intensification of the system was limited to short bursts of convection. By late October, convection began to wane, signifying an extratropical transition. On November 13, Peri was declared post-tropical.

Tropical Userstorm Carmen (CarmenWX34)

Intensity 35 mph, 1007 mbar
Movement WNW at 19 mpd

A tropical userwave exited the coast of Africa in early February 2017. However, it did not develop into a tropical userpression until June 8, when it was located southwest of Cabo Verde. The userpression eventually strengthened into a userstorm days later and was named Abdullah. The userstorm continued with little change in strength until mid-late June where the storm was downgraded into a tropical userpression after it had been reported to have weakened.

Severe Tropical Userstorm Addict (AhurricaneADDICTXD)

Severe tropical storm (JMA)
Tropical storm (SSHWS)
17S 2016-03-29 0440Z.jpg
Duration June 13, 2017 – January 16, 2018
Peak intensity 65 mph (100 km/h) (1-min)  990 mbar (hPa)

On June 10, a tropical userwave exited the coast of Africa. It developed into a tropical userpression by 00:00 UTC on June 13. The cyclone slowly strengthened into Tropical Storm Addict shortly thereafter as it continued to become better organized. In mid-July, it strengthened into a severe tropical userstorm. Afterward, the storm began to fluctuate in intensity, although still maintained winds of 60 mph (95 km/h). On January 16, 2018, Addict transitioned to an extratropical cyclone over the central north Atlantic.

Tropical Userstorm Minus (SymbolMinus)

Tropical userstorm (NUC)
Tropical storm (SSHWS)
Tony 2012-10-24 0520z.jpg
Duration July 21 – August 4
Peak intensity 50 mph (85 km/h) (1-min)  1004 mbar (hPa)
In mid-July, a non-tropical area of low pressure formed south of Bermuda. Initial organization was slow to occur. The low pressure area interacted with a tropical wave on July 20 as convection substantially increased, and the NUC initiated advisories on Tropical Userpression Thirteen on July 21. On the same day, the depression would strengthen into Tropical Userstorm Minus.

Tropical Userstorm Stacy (Thetrainboy989/Stacy54)

Tropical userstorm (NUC)
Tropical storm (SSHWS)
Ida 2015-09-20 1327Z.jpg
Duration July 22 – January 19, 2018
Peak intensity 50 mph (85 km/h) (1-min)  999 mbar (hPa)

A tropical userwave developed into a Tropical Userpression on July 22, and quickly strengthened into Tropical Userstorm Stacy later that day. It strengthened to its peak intensity later that day, with maximum sustained winds of 45 mph. Strong wind shear limited intensification, and the low-level center of the userstorm became exposed right after formation. NUC operationally treated the userstorm as a low and did not initiate advisories, due to the intermittent nature of the convection. Stacy opened up into a tropical userwave late on July 23. Stacy eventually regenerated on August 22, but strong wind shear limited further strengthening. Over the course of the next few months, Stacy was slow to strengthen, fluctuating in intensity multiple times.

Soon after reaching its initial peak intensity on July 22, Stacy sunk two boats in the open Atlantic. 5 people died as a result. The first boat had a family of three aboard. All three were lost and never found. The other boat had a group of friends aboard, two of which died after the sinking. The other three survived after being discovered by a boat that passed by. On January 5, Stacy began to rapidly accelerate towards Africa, and made landfall near Morocco. Stacy dissipated the same day, although its remnants stuck around for a few more days.

Usercane Cooper (Cooper7579)

Category 4 usercane (NUC)
Category 4 hurricane (SSHWS)
Usercane Cooper March 2018.png Usercane Cooper track.png
Duration August 3 – Active
Peak intensity 130 mph (215 km/h) (1-min)  941 mbar (hPa)
Main article: Usercane Cooper

On August 3rd, a tropical userwave exited the coast of Africa. A trough of low pressure interacted with the system, increasing the wave's convection while the two systems remained seperate. The wave gradually developed into a tropical userpression over the next few days until it became Tropical Userstorm Cooper. The storm moved slowly across the tropical Atlantic, strengthening into a Severe Tropical Userstorm on October 11th. On December 1, Cooper became the third (second fully tropical) usercane of the season. A rather small system, Cooper attained Category 2 intensity on January 5, 2018. Upon strengthening into a usercane on December 1, Cooper became the southernmost storm of usercane intensity, attaining this strength at 11.8 degrees latitude. Warm waters and a lack of vertical wind shear allowed the storm to strengthen further as its wind field expanded, and it became a major usercane on February 25, 2018. Cooper briefly intensified to reach Category 4 intensity on February 28, but it subsequently underwent an eyewall replacement cycle and weakened back to a Category 3 usercane on March 7.

Current Information

As of March 2, 2018, Usercane Cooper is located south of Hispaniola. Maximum sustained winds are at 120 mph (195 km/h). The minimum barometric pressure is at 951 hectopascals, and the system is moving northwest at 2 mpd.

Peak intensity 120 mph (195 km/h) (1-min)  953 mbar (hPa)

Tropical Userpression Thirty-Three developed from an upper-level trough on September 7. Tracking westward, the userpression quickly strengthened into Tropical Userstorm Prism. Afterward, Prism displayed healthy convection, but strengthened slowly, becoming a Severe Tropical Userstorm on November 19. Afterward, Prism yet again continued to organize but strengthen slowly until December 12, when it became the fourth (third fully tropical) usercane of the 2017 season. In early January 2018, Prism began to show signs of rapid intensification, with some models showing that it could possibly reach Category 3 intensity. However, Prism ran into shear before intensifying, and the round of strengthening never came into fruition. The storm continued to intensify, however, and it ultimately did become a major hurricane on March 17.

A tropical userwave merged with a trough of low pressure to create a broad area of low pressure west of Cape Verde. On October 13, this low strengthened into a tropical userpression, and then into Tropical Userstorm Fester a few days later. Unusually, Fester turned to the northeast as it slowly strengthened, and on November 9 the storm made landfall in Morocco. The remnants of Fester developed a new circulation before making landfall yet again in Portugal. Fester continued to form a new circulation every time it made landfall, but the storm only continued to make numerous landfalls in Europe.

Main article: Tropical Userstorm Tiger
A tropical userwave left the coast of Africa on November 18. Graudal strengthening occured, and the wave organized into a tropical userpression on November 21. Two days later, the userpression strengthened into Tropical Userstorm Tiger. Due to light wind shear, the storm strengthened slowly, with most of the convection displaced to the northwest of the system. Tiger was able to hold together, and in January of 2018 it began strengthening. Unusually, the storm's pressure was equivalent to that of a high-end Category 1 hurricane, although winds only reached 65 mph (100 km/h)
