A large area of showers and thunderstorms over the western Caribbean Sea has been moving W-NW. An area of low pressure is forecast to develop near or over the Yucatan Channel and there is a 60% risk that a tropical cyclone will form over the weekend then move north or northeastward into the eastern Gulf of Mexico towards Florida early next week. Locally heavy rains and some flooding are possible over portions of the Yucatan Peninsula, western Cuba and the Florida Peninsula during the next several days. There is also a possibility this system may reach tropical storm intensity prior to reaching the west coast of Florida.
