Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Thu Aug 13 2026

For the North Atlantic...Caribbean Sea and the Gulf of America:

Active Systems:
The National Hurricane Center is issuing advisories on recently
downgraded Tropical Depression Cristobal, located about 600 miles
west of the Azores.

Central Tropical Atlantic (AL92):
Showers and thunderstorms are showing signs of organization in
association with a tropical wave located about 1000 miles east of
the Lesser Antilles. This system will likely become a short-lived
tropical depression during the next day or two as it moves westward
across the tropical Atlantic. However, by late Friday, the system is
expected to move into a region of strong upper-level winds and dry
air, which should end its opportunity to develop. Interests in the
Lesser Antilles should monitor the progress of this system as gusty
winds and areas of heavy rain are possible Friday night and
Saturday, regardless of development.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 7 days...high...80 percent.

Eastern Tropical Atlantic (AL94):
A tropical wave located a few hundred miles south-southwest of the
Cabo Verde Islands is producing disorganized showers and
thunderstorms. Environmental conditions are forecast to be generally
conducive for gradual development, and a tropical depression could
form late this week or this weekend while the wave moves westward or
west-northwestward across the eastern and central tropical Atlantic.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...medium...50 percent.

Tropical Depression Cristobal Discussion Number   4
NWS National Hurricane Center Miami FL       AL032026
900 AM GMT Thu Aug 13 2026
 
Recent OSCAT data showed that Cristobal has weaken to a tropical
depression with max winds around 30 kt. The cyclone continues to
have a lack of deep convection based on satellite images. The most
current TAFB intensity estimates with a Final T number of 1.5 and
maximum winds of 30 kt. As a result, the initial intensity has
been brought down to 30 kt for this advisory.
 
Based on the increasingly harsh environmental conditions that the 
storm is entering as well as the latest model guidance, Cristobal is 
expected to continue weakening, and it is unlikely that convection 
will make a comeback.  Thus, the NHC forecast now calls for 
Cristobal to become a remnant low within the next 12 h, with 
dissipation following soon after. 
 
The current motion estimate is east-northeastward, or 075/14 kt.
The cyclone is expected to turn a bit more northeastward over the
next 12 h, and barely any changes have been made to the previous NHC
track prediction.
