Heavy storms are expected to roll into South Florida again on Tuesday, bringing waves of rain, possible hail, strong winds, lightning and flooded streets. A flood watch is in effect through the day and night.
"Another round today," CBS4 meteorologist Lissette Gonzalez said on Facebook.
Nearly nine inches of rain have fallen on South Florida over the past 12 hours, according to the National Weather Service, and an additional two inches are expected through Tuesday.
The region was pounded late Monday with several inches of rain, leading to street flooding and power outages in Miami-Dade and Broward counties.
Two people were reported to have been struck by lightning in Aventura around 10 p.m. in the area of Northeast 195th Street and Biscayne Boulevard. They were taken to an area hospital, condition unknown.
Hundreds were left in the dark as the rough weather caused power outages and flood advisories were issued for both counties. In Miami-Dade, the advisory was in effect until 3:30 a.m.
At Marlins Park in Little Havana, area streets flooded outside the stadium. The West Miami-Dade campus of Florida International University was pounded with more than five inches of rain and a nearby neighborhood had floodwaters of more than a foot high with impassable roads, according to the National Weather Service.
More rough weather is expected on Tuesday and beyond.
Weather radar shows heavy rain already moving across Kendall and Westchester.
Forecasters are predicting a 50 percent chance of rain and thunderstorms after 9 a.m. Tuesday and a 30 to 40 percent chance through Thursday.
Friday, the trend is expected to taper off with only about 20 percent of rain predicted.
"It's going to be a rather wet week," said Bob Ebaugh, a specialist at the National Weather Service.
Mondays severe weather prompted the weather service to issue alerts in Miami-Dade for hail and wind gusts. Flooding was reported in the western suburbs of Broward, before rolling east.
More than a dozen crashes littered major expressways as the afternoon rush hour began.
An upper level trough mixed with colder temperatures in high elevations is causing little cloud movement, Ebaugh said. Weak movement means stronger storms.
"When you have the development of storms and you have very little movement it adds up to a heavy rain event," Ebaugh said.
This week's storms are likely the arrival of South Floridas summer season when warm temperatures in the area brew up the daily afternoon rumbles.
"This could virtually be the advent of the rainy season," Ebaugh said.
During the week, temperature highs will be in the 80s with overnight lows dropping to about 75 degrees.
