Tropical Weather Outlook

Atlantic - Caribbean Sea - Gulf of Mexico
A broad area of low pressure over the northwestern Caribbean Sea is producing a large but disorganized area of cloudiness and thunderstorms. Environmental conditions appear to be favorable for some slow development before the system moves over the Yucatan Peninsula in a day or so. Heavy rains are expected to continue over Central America for the next few days, especially over portions of the Pacific Coast.

Elsewhere, tropical cyclone formation is not expected during the next 48 hours. 

Eastern and Central Pacific:
A nearly stationary area of low pressure located about 400 miles South-southwest of Manzanillo Mexico continues to show signs of organization. Upper level winds are expected to become more favorable and a tropical depression could form during the next day or two. This area is the subject of a Tropical Cyclone Formation Alert (TCFA) from the Joint Typhoon Warning Center (JTWC).

Elsewhere, tropical cyclone formation is not expected during the next 48 hours.

Western Pacific:
Tropical Depression 18W (Lingling) is located approximately 760 miles west-northwest of Midway Island and is forecast to become an extratropical low within 12 hours.(NOAA, National Hurricane Center, Central Pacific Hurricane Center and the Joint Typhoon Warning Center)
