Routine Tropical Cyclone Products for Atlantic to Now Begin May 15th 

On March 2nd, 2021, The Hurricane Network announced it will begin issuing routine tropical cyclone products for the Atlantic basin starting on May 15th, 2021. After the 2020 hurricane season, The Hurricane Network conducted a technical and climatological review of the past hurricane seasons in a decade.

Given the recent trend of an increase of off-season tropical cyclone activity in May, The Hurricane Network approved the service change of changing the routine shifts from June 1 to May 15. The Hurricane Network would like to stress that the Atlantic Hurricane Season continues to officially start on June 1, as always.

The World Meteorological Organization is studying the ramifications of officially changing the date of the Atlantic Hurricane Season to May 15 instead of June 1.

That being said, The Hurricane Network will issue the first routine Tropical Cyclone Outlook for the Atlantic on May 15th, 2021 which will also coincide with the first Eastern Pacific Tropical Cyclone Outlook. As always though, Special Tropical Cyclone Outlooks will be issued as conditions warrant.
