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

Eastern Tropical Atlantic: 
Shower and thunderstorm activity associated with a tropical wave 
located several hundred miles west-southwest of the Cabo Verde 
Islands has decreased since yesterday.  This system is expected to 
move westward to west-northwestward at 15 to 20 mph across the 
tropical Atlantic during the next several days, and significant 
development is becoming less likely.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.

For the eastern North Pacific...east of 140 degrees west longitude:

Active Systems:
The National Hurricane Center is issuing advisories on Tropical 
Storm Howard, located about 750 miles west of the southern tip of 
the Baja California peninsula.

Offshore of Southwestern Mexico:
Satellite-derived wind data from earlier this afternoon indicate 
that a broad area of low pressure located several hundred miles 
south of the southwestern coast of Mexico has an elongated 
circulation without a well-defined center.  However, the low 
continues to produce a large area of showers and thunderstorms.  
Environmental conditions appear conducive for development of this 
system, and a tropical depression is likely to form by this weekend 
while it moves west-northwestward to northwestward at about 10 mph, 
well offshore the coast of Mexico.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...80 percent.

  • Tropical Storm Howard Forecast Discussion Number 18
    Issued at 200 PM PDT Wed Aug 10 2022 000 WTPZ44 KNHC 102037 TCDEP4 Tropical Storm Howard Discussion Number 18 NWS National Hurricane Center Miami FL EP092022 200 PM PDT Wed Aug 10 2022 The infrared satellite appearance of Howard has continued to degrade this afternoon with little to no deep convection remaining. The latest subjective Dvorak intensity estimate from TAFB supports lowering the analyzed intensity to 45 kt for this advisory. Howard should continue to weaken this evening as it moves over progressively cooler waters and into a drier and more stable environment. Numerical guidance suggests Howard will not reacquire any sustained deep convection, however, periodic brief pulses of convection are possible over the next 12 - 24 h. The official forecast shows Howard becoming a post-tropical cyclone within the next 12 h, and it could happen as soon as this evening. The cyclone should open into a remnant trough by 60 h. Howard continues to move west-northwestward with an initial forward speed of 10 kt. A slight turn to the west is expected over the next two days before the cyclone dissipates. No substantial changes were made to the NHC track forecast, which remains based on the model consensus.
