MIAMI — Many parts of South Florida experienced flash flooding Monday afternoon due to heavy downpours that dumped more than 4 inches of rain in under an hour in some areas.

The torrential showers began over the weekend, didn’t relent Monday and are expected to last through Tuesday.

The National Weather Service issued flash flood warnings for Miami, Miami Beach and North Miami that were expected to continue into early Monday evening. Parts of the Keys also saw flooding.

The weather rendered many streets impassible.

Federal forecasters also issued special marine warnings for the Atlantic Ocean and the Gulf of Mexico and warned boaters not to go out on the water. Some wind gusts of more than 40 knots were recorded with heavy downpours, forecasters said.

The National Weather Service in Key West reported a waterspout inside a thunderstorm in the Florida Straits that extended 20 nautical miles beyond the Upper Keys Monday afternoon.

The Middle Keys city of Marathon received 14.59 inches of rain by 3 p.m. Monday, which is almost an inch away from setting the record for the month of May, which was set in 1968, according to NWS Key West.

By 3:30 p.m. Monday, NWS meteorologists were tracking a strong thunderstorm near the Miccosukee Resort in southwest Miami-Dade. It was moving northeast at 20 mph and forecasters said winds of 45 mph and funnel clouds could develop from it.

Locations impacted include Miami, Hialeah, Fort Lauderdale, Pembroke Pines, Hollywood, Miramar, Davie, Plantation, Sunrise, Tamarac, Hallandale, Miami Gardens, Kendall, Lauderhill, Weston, North Miami, Doral, North Miami Beach, Aventura and Lauderdale Lakes.

The wet and windy weather put a halt to outdoor plans for what was expected to be a busy Memorial Day holiday weekend.

The Florida Fish and Wildlife Conservation Commission reported that Saturday, before the storms moved in, was a busy day on the water, but there were no boating accidents, and one arrest for boating under the influence of alcohol, said Officer Ronald Washington.

The Keys had several BUI arrests Friday and Saturday, as well as one person who went missing for more than two hours Saturday afternoon after a wave knocked him off his personal watercraft near Key Largo, said FWC Officer Bobby Dube.

All the bad weather is due to a wave squeezing lots of tropical moisture on the region, CBS4 meteorologist Jennifer Correa said.
