Plain-language outlook

In the Atlantic over the next 48 hours, three areas are being watched: a cluster of storms about 490 miles southeast of Bermuda that has a low chance of becoming a tropical depression or tropical storm and could mean heavier rain and rough seas near Bermuda by Sunday into Monday. A strong non-tropical low well west of Portugal could briefly gain some tropical traits and bring rain to Portugal and northwest Spain tonight into Sunday. A third area has little to no chance of developing in this window.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 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 tonight 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 by 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:
Satellite imagery indicates that a broad area of low pressure has
formed in association with the shower and thunderstorm activity a
few hundred miles east-southeast of Bermuda. Additional slow
development of this system is possible during the next few days as
it drifts westward on Sunday and then accelerates northward early
next week.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...30 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.
