2021 Atlantic hurricane season (Default)

The 2021 Atlantic hurricane season was an average season, which featured 15 total tropical depressions, 14 named storms, 9 hurricanes, and 3 major hurricanes. The season officially began on June 1st, and officially ended on November 30th, but tropical cyclogenesis can occur outside of these boundaries, as seen with Subtropical Storm Ana, which formed as a subtropical depression on May 28th. The season was ultimately expected to be below average, but due to the replacement of an El Nino, and a bit warmer sea surface temperatures, an above average season occured.

Subtropical Storm Ana
On May 26th, the NHC began monitoring a large non-tropical low, just north of Bermuda. The system was mainly just a convectionless swirl, but it was forecast to move into favorable conditions. Advisories were initialized on Subtropical Depression 01 at approximately 6:00 UTC, on May 28th. As it continued movement into slightly more favorable waters, an airforce recon jet confirmed 45 MPH wind speeds in the system, calling for the NHC to upgrade it into Subtropical Storm Ana. The system began moving northwards, and ran into unfavorable conditions. Ana began weakening steadily, transitioning into a post-tropical system only two days after its formation.
