SPECIAL TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
935 AM EDT SUN AUG 10 2025
FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF AMERICA:
SPECIAL OUTLOOK ISSUED TO UPDATE DISCUSSION OF THE DISTURBANCE
LOCATED SOUTHEAST OF THE CABO VERDE ISLANDS (AL97).
EASTERN TROPICAL ATLANTIC (AL97):
UPDATED: RECENTLY RECEIVED SATELLITE-DERIVED WIND DATA INDICATE
THAT A WELL-DEFINED LOW PRESSURE SYSTEM HAS FORMED ABOUT MIDWAY
BETWEEN THE WEST COAST OF AFRICA AND THE CABO VERDE ISLANDS WITH
MAXIMUM WINDS OF ABOUT 35 MPH. ALTHOUGH THE ASSOCIATED SHOWER AND
THUNDERSTORM ACTIVITY STILL LACKS SOME ORGANIZATION, ONLY A SMALL
INCREASE IN THE ORGANIZATION COULD LEAD TO THE FORMATION OF A
TROPICAL DEPRESSION BEFORE THE LOW MOVES NEAR OR ACROSS THE CABO
VERDE ISLANDS TONIGHT AND ON MONDAY. REGARDLESS OF DEVELOPMENT,
LOCALLY HEAVY RAINFALL AND GUSTY WINDS ARE POSSIBLE TODAY AND MONDAY
ACROSS THE CABO VERDE ISLANDS, AND INTERESTS THERE SHOULD MONITOR
THE PROGRESS OF THIS SYSTEM.
EVEN IF A TROPICAL DEPRESSION DOES NOT FORM OVER THE NEXT DAY OR SO,
ENVIRONMENTAL CONDITIONS APPEAR CONDUCIVE FOR LATER DEVELOPMENT,
AND A TROPICAL DEPRESSION IS LIKELY TO FORM BY THE MIDDLE TO LATTER
PORTION OF THIS WEEK WHILE MOVING WEST-NORTHWESTWARD AT 15 TO 20 MPH
ACROSS THE EASTERN AND CENTRAL TROPICAL ATLANTIC.
* FORMATION CHANCE THROUGH 48 HOURS...MEDIUM...40 PERCENT.
* FORMATION CHANCE THROUGH 7 DAYS...HIGH...80 PERCENT.
CENTRAL ATLANTIC (AL96):
DISORGANIZED SHOWERS AND THUNDERSTORMS CONTINUE IN ASSOCIATION WITH
A TROUGH OF LOW PRESSURE LOCATED OVER THE CENTRAL TROPICAL
ATLANTIC. DEVELOPMENT OF THIS SYSTEM SHOULD BE SLOW TO OCCUR
DURING THE NEXT COUPLE OF DAYS DUE TO SURROUNDING DRY AIR, BUT SOME
GRADUAL DEVELOPMENT IS POSSIBLE DURING THE MIDDLE PART OF THIS WEEK
WHILE THE SYSTEM MOVES NORTHWARD OVER THE CENTRAL ATLANTIC.
* FORMATION CHANCE THROUGH 48 HOURS...LOW...10 PERCENT.
* FORMATION CHANCE THROUGH 7 DAYS...LOW...20 PERCENT.
