Special Tropical Weather Outlook
NWS National Hurricane Center Miami FL
740 AM EDT Thu May 24 2018

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

1. A broad, stationary surface low pressure system centered over the
southeastern Yucatan Peninsula is gradually becoming better defined.
Although showers and thunderstorms, along with strong gusty winds,
are confined primarily to the adjacent waters of the northwestern
Caribbean Sea, gradual development of this system is expected during
the next couple of days as it drifts northward near the Yucatan
Peninsula. Environmental conditions are forecast to become more
conducive for development through early next week, and a subtropical
or tropical depression is likely to form by late Saturday over the
southeastern Gulf of Mexico. Regardless of development, locally
heavy rainfall is forecast across western Cuba and over much of
Florida and the northern Gulf Coast into early next week. In
addition, the threat of rip currents will steadily increase along
the Gulf coast from Florida westward to Louisiana over Memorial Day
weekend. For more information on these threats, please see products
issued by your local weather office. The next Special Tropical
Weather Outlook on this system will be issued by 200 PM EDT this
afternoon.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...high...80 percent.
