Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Sat Sep 18 2021

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

The National Hurricane Center is issuing advisories on Tropical 
Storm Odette, located several hundred miles off the Mid-Atlantic 
U.S. coast.

1. Showers and thunderstorms continue to become better organized in 
association with an area of low pressure located less than 1000 
miles east-southeast of the northern Leeward Islands. Environmental 
conditions are expected to be conducive for further development 
during the next day or two, and a tropical depression is likely to 
form later today or tomorrow while the system moves toward the 
west-northwest at about 15 mph.  This system is expected to be near 
the northern Leeward Islands on Monday and Tuesday, and interests 
there should monitor the progress of this disturbance.  Upper-level 
winds are likely to become less conducive for development when the 
system reaches the southwestern Atlantic by the early to middle part 
of next week.  
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

2. An area of low pressure located several hundred miles 
south-southwest of the Cabo Verde Islands has developed a more 
concentrated area of showers and thunderstorms, primarily west of 
the center. This system is currently nearly stationary, but is 
expected to begin moving towards the northwest at 5 to 10 mph over 
the far eastern Atlantic where some additional development is 
possible over the weekend.  However, by early next week, further 
development appears unlikely as the system is forecast to move into 
less conducive upper-level winds and over cooler waters.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...low...30 percent.
