Special Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1000 AM EDT Wed Aug 12 2026
For the North Atlantic...Caribbean Sea and the Gulf of America:
Updated for the Central Atlantic Sub-Tropical System.
Central Tropical Atlantic (AL92):
An area of showers and thunderstorms associated with a tropical wave
is located about 900 miles west-southwest of the Cabo Verde
Islands. Environmental conditions are forecast to be conducive for
development during the next couple of days, and a tropical
depression will likely form while the system moves westward to
west-northwestward across the central tropical Atlantic.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 7 days...high...80 percent.
Central Subtropical Atlantic (AL93):
Recent satellite wind data indicate that the circulation
associated with the low pressure area located about 1050 miles
east-northeast of Bermuda has become better defined and the
system is producing tropical-storm-force winds to the southeast of
the center. The system is likely to become a short-lived tropical
storm while it moves eastward to east-northeastward at around 20 mph
across the central subtropical Atlantic. Addition information on
this system is found in High Seas Forecasts issued by the National
Weather Service.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 7 days...high...80 percent.
Eastern Tropical Atlantic:
A tropical wave just offshore of the coast of west Africa is
producing disorganized showers and thunderstorms. Environmental
conditions are forecast to be generally conducive for some
development of this system during the next several days while it
moves westward or west-northwestward across the eastern and central
tropical Atlantic.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...30 percent.

Tropical Storm Cristobal Forecast Discussion Number 1
Issued at 300 PM GMT Wed Aug 12 2026000 WTNT43 KNHC 121451 TCDAT3 Tropical Storm Cristobal Discussion Number 1 NWS National Hurricane Center Miami FL AL032026 300 PM GMT Wed Aug 12 2026 The circulation associated with the area of low pressure we have been monitoring well east-northeast of Bermuda over the past several days has become better defined today. A recent ASCAT pass revealed an area of 35-40 kt winds southeast of the slightly elongated and exposed center, within the region of convection. While the convective organization has degraded since earlier this morning, scatterometer data indicate that the system has achieved tropical storm status, and it likely reached that threshold earlier this morning. Therefore, advisories are being initiated on Tropical Storm Cristobal, with the initial intensity set to 40 kt. Cristobal is moving quickly eastward around 22 kt over marginally favorable sea surface temperatures near 25 C. The storm is currently positioned between a subtropical high to the south, and a ridge extending over the north-central Atlantic to the northeast. A turn toward the northeast, accompanied by a gradual decrease in forward speed, is expected later today and tonight as Cristobal moves along the southwestern periphery of the northern Atlantic ridge. Slow weakening is forecast during this period as the storm moves over progressively cooler waters and encounters increasingly dry mid-level air and stronger northerly wind shear. Cristobal is expected to be short-lived and dissipate on Thursday. The official NHC track and intensity forecasts lie near the middle of the consensus guidance and are closest to the HCCA solution.
