Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Thu Sep 26 2024

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

Active Systems:
The National Hurricane Center is issuing advisories on Hurricane 
Helene, located over the southeastern Gulf of Mexico and on newly 
formed Tropical Storm Isaac, located over the central Subtropical 
Atlantic Ocean. 

1. Eastern and Central Tropical Atlantic (AL98):
Showers and thunderstorms have increased this morning in association 
with a broad area of low pressure along a tropical wave located 
several hundred miles west of the Cabo Verde Islands. However, 
earlier satellite wind data suggested the system still lacks a 
well-defined circulation.  Environmental conditions appear favorable 
for gradual development of this system, and a tropical depression is 
likely to form during the next day or two while it moves westward to 
west-northwestward at around 15 mph across the eastern and central 
tropical Atlantic.
* Formation chance through 48 hours...high...70 percent. 
* Formation chance through 7 days...high...80 percent.


Public Advisories on Tropical Storm Isaac are issued under WMO 
header WTNT35 KNHC and under AWIPS header MIATCPAT5. 
Forecast/Advisories on Tropical Storm Isaac are issued under WMO 
header WTNT25 KNHC and under AWIPS header MIATCMAT5.
