Broward, Miami-Dade under new flood watches with forecast calling for more heavy rain

Tropical Storm Alex isn’t done with South Florida yet.

Parts of the region are again under a flood watch, through at least the end of Tuesday, because the region was already swamped from heavy rain over the weekend from the disturbance that became Tropical Storm Alex.

The National Weather Service in Miami issued the flood watch on Monday for coastal Broward and Miami-Dade counties.

The potential for excessive rain begins Monday afternoon and extends until the end of Tuesday because of a trailing edge of Tropical Storm Alex, which is well out in the Atlantic Ocean.

The National Weather Service on Monday said that because of the heavy saturation from the weekend rain, an additional rainfall total of up to 6 inches might generate localized flash flooding.

Estimated rainfall totals for South Florida for Friday and Saturday show nearly 15 inches in Hollywood and Margate, and about 10 inches in Boca Raton and Pompano beach.
