BOCA RATON, FL (BocaNewsNow.com) (Copyright © 2023 MetroDesk Media, LLC) (Updated 5 p.m.) — The National Hurricane Center is watching two systems that could develop into systems of note over the next several days. The yellow oval just off the coast of Florida is likely to develop into something that could affect the Carolinas. It’s too soon to know, but the proximity to the U.S. Mainland is notable. The NHC is also watching that “red oval” just off the coast of Africa. It is expected to become a tropical depression within days. We note that ovals indicate where a system may form, not necessarily a direction of travel.
Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 PM EDT Tue Sep 19 2023
For the North Atlantic… Caribbean Sea and the Gulf of Mexico:
Active Systems: The National Hurricane Center is issuing advisories on Hurricane Nigel, located over the central subtropical Atlantic.
1. Eastern Tropical Atlantic: A tropical wave is expected to move off the west coast of Africa by Wednesday. Environmental conditions are forecast to be conducive for gradual development of the wave thereafter, and a tropical depression is likely to form late this week or this weekend while the system moves generally westward across the eastern and central tropical Atlantic.
* Formation chance through 48 hours…low…near 0 percent.
* Formation chance through 7 days…high…70 percent.
2. Western Atlantic: A non-tropical area of low pressure is expected to form east of the Florida peninsula late this week. This system could acquire some subtropical characteristics this weekend while it moves generally northward. Regardless of subtropical development, this low is likely to bring gusty winds, heavy rain, and high surf conditions to portions of the coastal Carolinas into the coastal Mid-Atlantic states late this week into this weekend. Please see products from your local National Weather Service office for more details.
* Formation chance through 48 hours…low…near 0 percent.
* Formation chance through 7 days…low…30 percent.
