ologist Andrew Hagen said.
“If you get 2 inches spread out over a couple of hours it’s not so bad,” he said. “But if you get 2 inches in one hour, that’s when we start seeing significant ponding of water, especially in low-lying areas.”
A flood advisory was in effect at 1 p.m. for Key Biscayne, south Miami Beach and downtown Miami.
“If you get 3 inches of rain in an hour then that can make some areas impassable,” he said.
The downpours may reduce visibility and cause the ponding of water on area roads. Motorists should slow down, use low beam headlights, and allow extra time to reach their destination, forecasters said.
Temperatures are expected to reach the high 80s and low 90s in some areas, but the heat index will make it feel like 105.
We can also expect scattered showers and storms through Wednesday, according to the National Weather Service.
