The 2047 Atlantic Hurricane Season was a hyper-active hurricane season, as well as the most active hurricane season on record since 2004. The 2047 season caused an estimated 4,000 deaths and approximately $207.4 billion in damages, and is one of the deadliest, as well as one the costliest Atlantic hurricane seasons on record. The 2047 Atlantic hurricane season featured a total of 35 depressions, 31 total storms, 19 hurricanes and 8 major hurricanes, and is the second Atlantic hurricane season to use the Greek alphabet since 2004, and lasted into February of the next year.
Tropical Storm Arlene was one of the earliest forming tropical cyclones on record to impact the state of Florida. Originating from a broad disturbance over warmer than normal Caribbean waters, moved into the Gulf of Mexico to become a moderate tropical storm. Arlene then made landfall in northern Florida. Two people were killed as a result of flooding, and Arlene caused up to $10 million in damages. Arlene dissipated on February 28, as it became a nor'easter and dumped snow in the northeast.
The season saw a significant jump in activity in mid-July, starting with Hurricane Cindy, which was the season's first major hurricane, as well as the first storm to make landfall as a hurricane in the 2047 Atlantic hurricane season. Cindy originated from a nascent disturbance in the central Caribbean, south of the Tiburon Peninsula. The disturbance was quickly named tropical storm Cindy on July 15th. Cindy then began to intensify, and became a category three hurricane but for a short time. Hurricane Cindy made a sharp turn to the northeast, subsequently landfalling on the western tip of Cuba with considerable damage on July 19th. Afterwards, Cindy weakened to a tropical storm, but re-intensified into a category 1 hurricane after it moved over the Bahamas. Finally, after a few days, Cindy encountered strong wind shear and degenerated into a remnant low before dissipating on the 24th of July. Overall, Cindy caused upwards of $64 million in damages, and caused 43 fatalities. Because of the destruction Cindy caused, the name Cindy was retired and replaced with Charlotte in 2053 and will never be used again in a hurricane season.
Hurricane Dylan was the season's first hurricane to form in the MDR (Main Development Region) on July 22nd. Dylan formed from a surface trough near the ITCZ, and had a well-defined satellite presentation, east of the Lesser Antilles. Rapid development ensued, and a period of rapid intensification occurred and Dylan strengthened from a strong tropical storm to a category two hurricane in around 18 hours. However, this ocurred before Dylan encountered an upper-level trough, which sheared Dylan's convection apart, causing Dylan to rapidly weaken. Wind shear slowly relaxed after July 25th, as Dylan's direction turned west-southwest, and Dylan began to target the Lesser Antilles. On July 27th, Dylan passed over the island of Martinique before entering the Caribbean Sea. On July 28th, conditions appeared more favorable, as Dylan began to reintensify back into a category one hurricane. A change in the steering patterns caused Dylan to loop over a small area, before turning northward and briefly becoming a category two hurricane. This time, dry air and more wind shear caused Dylan to slowly weaken as it passed over the British Virgin Islands on July 30th. On July 31, Dylan weakened to a tropical storm and eventually the circulation was exposed. This would cause Dylan to transition into a remnant low, and meandered south of Bermuda for a couple days until Dylan dissipated on August 3. Five deaths and $17 million in damages can be attributed to Dylan. Despite the damage and deaths Hurricane Dylan caused, the name was not retired and will be used again in the 2053 Atlantic Hurricane Season.
Despite the 2047 Atlantic hurricane season being hyperactive, September was an inactive month, with only two named storms. The most notable of which, Harvey, which was a catastrophic and costly category five hurricane for the Bahamas, and the southeast United States as a category four hurricane. Hurricane Harvey's precursor was a typical Cape-Verde tropical wave moving west, battling dry air and shear before conditions became very favorable for development. On September 15, Harvey formed from the precursor disturbance, and became a tropical storm on the 16th. Then, very warm waters and low wind shear of less than 10 kt allowed Harvey to explosively intensify. Harvey strengthened from a tropical storm to a category two hurricane in just 6 hours, making Harvey's intensification the fastest on record. Harvey became a category five hurricane before mowing down several of the islands of the Bahamas at peak intensity.
The season officially began June 1, and ran through November 30, which conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. Despite this, the first named storm, Arlene, which formed on February 21st, months before the official start of the hurricane season. The last named storm, hurricane Zeta, was the latest forming hurricane on record, since 2004.
The hyperactive hurricane season came to fruition due to a multitude of different factors: a moderate La Nina, which seasonal forecasts correctly predicted beforehand. September featured the most activity, with a majority of the major hurricanes forming through the late-August through Mid-October period with the disaster of hurricane Katia, which destroyed parts of Jamaica and southern Cuba as a category five hurricane. Hurricane Idalia was a destructive storm for parts of the Southeast states as a category four on the Saffir-Simpson Hurricane Wind Scale.
Towards late October, the 2047 Atlantic Hurricane season reached the Greek Alphabet for the second time in recorded history, following the deadly and hyperactive 2004 Atlantic Hurricane Season. Hurricane Gamma was the farthest east category four hurricane on record; Tropical Storm Epsilon was the first and costliest November storm in over 25 years in Bermuda. Besides that, activity quickly died down due to multiple cold wakes left from previous storms, and increasing wind shear. However, in late December, the last named storm or hurricane formed on December 29th: Hurricane Zeta, which was a minimal impact cyclone in the Caribbean and dissipated on January 5th, crossing over into the 2048 Atlantic Hurricane Season.
