The 2021 Atlantic hurricane season was the second most active Atlantic hurricane season since record-keeping began in 1851. Due to an unusually strong Azores High, most storms were directed more southerly than usual. As a result, the Yucatan Peninsula was severely affected by tropical cyclones throughout the year.
Storms[]
Tropical Storm Ana[]
| Tropical storm (SSHWS) | |
  | |
| Duration | May 13 – May 15 |
|---|---|
| Peak intensity | 85 km/h (50 mph) (1-min) 999 hPa (mbar) |
On May 10, a large extratropical system moved eastward into the Gulf of Mexico from the Rio Grande valley. Situated in a region temporarily favorable for tropical cyclogenesis, the extratropical system stalled, and the National Hurricane Center (NHC) noted its potential for tropical development on May 12. Late that day, convection began to coalesce near the center of the extratropical system. At 0600 UTC the following day, the storm was classified as Tropical Depression One, the first of the season. At the time, environmental conditions were unusually more supportive of tropical storm development for this time of year, and as such the depression gradually organized into a tropical storm by 0600 UTC on May 14. Moving northeastward, the tropical storm grew larger and reached its peak intensity with maximum sustained winds of 45 mph (85 km/h) and a minimum pressure of 999 mbar (hPa; 29.50 inHg). Ana made landfall near Crawford, Florida at 1245 UTC later that day. Once inland, Ana rapidly weakened before degenerating into an extratropical storm at 0600 UTC on May 15 near Savannah, Georgia.
Due to the tropical storm's quick forward motion and large size, rainfall was widespread but was relatively light in most locations. Precipitation peaked at 10.21 in (259 mm) near Apalachicola, Florida. The heavy rains caused several creeks in Georgia and the Florida panhandle to overflow their banks, though rain-related damage remained minimal. Off the coast, the storm caused turbulent seas, with storm surge heights peaking at 4.6 ft (1.2 m) in Goose Creek Bay. The waves caused several shipping boats to capsize in Apalachicola Bay, killing 2 people. Further inland, winds from Ana caused a majority of the damage. The strong winds knocked down power lines, causing power outages to over 50,000 people at one point on May 15. Strong winds also fanned fires in southern Florida, which caused widespread property damage. Overall, damages from Ana totaled $275,000.
