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
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.
