MY 2025 ATLANTIC HURRICANE SEASON BIRDSEYE VIEW POST #55A (Special Update)

*******Note that forecasts and outlooks in this post are NOT the official forecast from the National Hurricane Center (NHC). They are my own detailed views on the Atlantic tropics based on current observations and latest computer model runs. As such do not make decisions based on my posts...consult news media...watches and warnings from your local weather office...and any evacuation orders issued by local governments to make the most informed and best decisions.

Currently working on my next full update on the Atlantic tropics to be released within the next few hours. In the meantime this special update is to provide a briefing on the following:

(1) Changes with the large eastern Atlantic tropical wave of low pressure which recently emerged from Africa... tagged as area of interest #16 on this site... which has developed a smaller organized spin within heading for the Republic of Cabo Verde Islands.

(2) A new disturbance in the eastern Gulf of America which will be tagged as area of interest #17 in the next update.

Refer to previous full update #55 for more information on activity elsewhere in the Atlantic tropics (https://www.infohurricanes.com/post/my-2025-atlantic-hurricane-season-birdseye-view-post-55).

AREA OF INTEREST #16... Satellite image of large tropical wave of low pressure currently in the eastern tropical Atlantic from 1740Z today... which has developed a small tropical low pressure spin within its east side heading for the Republic of Cabo Verde Islands:

The large size of the tropical wave that emerged from western Africa late Friday and early Saturday was re-enforced while absorbing a previously inactive wave southwest of the Republic of Cabo Verde Islands. A smaller low pressure spin with increasingly organized thunderstorm bands has developed within the east side of the large wave and as of today the National Hurricane Center has increased short-term odds of tropical cyclone formation to 50%. The tropical low is moving northwest toward the Republic of Cabo Verde Islands due to the cyclonic flow of the rest of the large wave... and will eventually turn west while bumping into the Atlantic surface ridge. Based on visible satellite animation and computer model runs... the center of the tropical low is on a trajectory toward the northern islands... and regardless of short-term tropical cyclone formation or not has potential to bring periods of heavy rainfall and gusty winds within to all of the islands in the next 24 hours. As the tropical low moves across the northern islands at 24 hours... then as it pulls away from the islands through 48 hours... its development is likely to be initially dampened by dry Saharan air and marginal sea-surface temperatures. In the longer range its development risk increases while reaching warmer waters and lower concentrations of dry Saharan air toward the west.

AREA OF INTEREST #17... Satellite image of a lengthy surface trough of low pressure moving closer to the southeastern United coast as of 1740Z today... an organizing thunderstorm cluster is seen at the southwest end of the trough in eastern Gulf of America waters offshore of southwestern Florida:

The southwest end of the surface trough of low pressure straddling the Florida peninsula and nearing the southeastern United States coast has fired a thunderstorm cluster in the eastern Gulf of America and just offshore of the southwestern Florida peninsula coast. This feature will mark the seventeenth tropical Atlantic area of interest tracked on this site this year. The steering feature is a surface ridge currently over the coastal northeastern US... and this disturbance will continue northwest toward the western Florida panhandle... southern Alabama... and southeastern Mississippi through Tuesday. Interests here should be aware of this disturbance for possible Tuesday impacts including potential heavy rainfall with flash flooding... with gusty winds and surf toward the coast should tropical cyclone formation occur.
