After receiving more than 6 inches yesterday, parts of the Miami Metro area will again be subject to flooding later Sunday.
One of the first cold fronts to reach South Florida all season will collide with deep tropical moisture. The result will be heavy rain-producing thunderstorms. The heaviest rainfall will likely be across the heavily populated portions of Miami-Dade and Broward counties.
Thunderstorms usually set up just west of the populated areas, across the Everglades. However, the approaching cold front will cause the Atlantic sea breeze to be pinned at the coast, over the populated areas. The sea breeze will collide with westerly winds associated with the cold front to form the thunderstorms.
There is so much moisture in the atmosphere, any thunderstorms that form will be capable of producing 2-4 inches of rain in just an hour.
