Tropical wave bringing moisture as it approaches Central Florida

Tropical wave bringing moisture as it approaches Central Florida

While weak tropical disturbances, called tropical waves, have been moving westward from Africa all summer, this is the time of the year when conditions become more conducive for development of these disturbances to tropical storms and hurricanes.

While no significant development of the system was expected for the next few days while it moves westward at 15 to 20 miles per hour, upper-level winds could become more conducive for development by the weekend while the wave continues westward across the central Atlantic. They now say there is a "high chance" that the system will become a tropical depression or storm within the next five days.

This feature has a 50/50 chance of becoming a tropical depression from late this week through this weekend to the east of the Windward and Leeward Islands.

"Rain chances will be high, in the 70% to 80% range, with locally heavy rainfall amounts", Campos said.

In anticipation of the heavy rain this weekend, NOAA's Weather Prediction Center has issued a "marginal risk" for flash flooding over much of South Florida on Friday.

Hurricane season runs from June 1 through November 30.

A tropical wave will approach the Florida Straits Thursday night, ushering in deep tropical moisture and increasing rain chances, according to Campos. A tropical depression could form by early next week, several hundred miles east of the Lesser Antilles. The system is surrounded by dry air and dust from the Saharan Desert which is UNFAVORABLE for development as well as moderate upper level wind shear. Also stronger wind shear continues over these areas.

Portions of Puerto Rico and the Bahamas are experiencing showers and thunderstorms, and these will continue as it moves to the northwest then north, according to the National Hurricane Center.

It is way too soon to say whether this tropical system will affect the United States.
