Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Sat Aug 22 2026
For the North Atlantic...Caribbean Sea and the Gulf of America:
Northeastern Atlantic:
A strong non-tropical area of low pressure is located over the
northeastern Atlantic several hundred miles west of the coast of
Portugal. This system could acquire some subtropical or tropical
characteristics later today or on Sunday while it moves
east-southeastward at 10 to 15 mph toward Portugal and northwestern
Spain. The opportunity for tropical or subtropical development
should end Sunday night when the system encounters unfavorable
environmental conditions. For more information, see High Seas
Forecasts issued by Meteo France.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...20 percent.
Central Subtropical Atlantic:
A trough of low pressure located over the central subtropical
Atlantic a few hundred miles east of Bermuda is producing
disorganized shower activity. Development of this system, if any, is
expected to be slow to occur while it drifts westward through Sunday
and then accelerates northward early next week. By the middle of
next week, the system could merge with a frontal boundary over the
north Atlantic, which should diminish any remaining chances of
development.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...20 percent.
Eastern Tropical Atlantic:
A tropical wave is expected to move off the west coast of Africa on
Monday. An area of low pressure could form in association with the
wave soon after it moves off the coast. Environmental conditions are
marginally conducive for development, and a tropical depression
could form by the middle to latter portions of next week while the
system moves westward at 15 to 20 mph across the eastern and central
tropical Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...40 percent.
