Tropical Weather Outlook

200 AM EDT Tue Aug 11 2026
For the North Atlantic...Caribbean Sea and the Gulf of America:
Central Tropical Atlantic:
Shower and thunderstorm activity is currently limited in association
with an area of low pressure located about 500 miles southwest of
the Cabo Verde Islands. Environmental conditions are forecast to
gradually become more conducive for development during the next day
or two, and a tropical depression will likely form during the latter
half of this week while the system moves westward to
west-northwestward across the central tropical Atlantic.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...high...70 percent.
East of the Windward Islands:
Disorganized showers and thunderstorms associated with a tropical
wave are located about 850 miles east of the Windward Islands. Some
gradual development of this system is possible through the next day
or two while it moves quickly westward across the central tropical
Atlantic. The system is expected to encounter a large area of
environmental dry air by the time it reaches the Windward Islands
Wednesday night, which should end its chances for development.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.
Central Subtropical Atlantic:
A trough of low pressure located several hundred miles northeast of
Bermuda is producing disorganized showers and thunderstorms. Some
development of this system is possible during the next couple of
days while it moves eastward at around 20 mph across the central
subtropical Atlantic. The system is forecast to reach cooler waters
later this week, ending its chances of formation by Thursday.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.
