Get some sunshine when you can this week, because the rain is expected to continue through at least Friday with the wettest periods during the afternoon hours.
The area of low pressure in the Gulf of Mexico continues to pull tropical moisture into the state. National Hurricane Center forecasters are giving the disturbance only a 10 percent chance of developing into a tropical or subtropical system over the next five days.
Despite development, it will bring more wet weather to South Florida as it creeps north toward the Panhandle this week.
With the focus of the low further north and west over the course of the week, National Weather Service meteorologists expect showers and thunderstorms to be stirred up by daytime heating.
That means most of the bad weather, including some thunderstorms will be in the afternoon.
“Also, the risk of intense convection will go down as well, although at least some concern for waterspouts will remain in the highly tropical air mass,” NWS forecasters wrote this morning.
Rainfall totals through Monday for South Florida are between 3 to 7 inches, with the highest amounts alone the east coast. Training or stalled thunderstorms could lead to much higher amounts in localized areas.
Three tornadoes zipped through Florida during Monday’s storms, including an EF-0 that hit in western Palm Beach County. The other weak tornadoes were in Brevard and Martin counties.
The Palm Beach County tornado, judged to be an EF-0 with up to 80 mph winds, touched down at 5:34 a.m. near 71st Place North and Apache Blvd. It ripped a 1.5 mile-path northwest across Seminole Pratt Whitney Road before lifting four minutes later near Valencia Blvd. and Banyan Blvd.
In the short rampage, the twister tossed trampolines, toppled a bunny cage and a chicken shed, shredded pool screens, knocked on doors loud enough to set off a burglar alarm, obliterated at least one shed and uprooted a tree in the paddock of an 18-year-old horse named Flash.
Mike Jordan, Flash’s keeper, said he was watching the news when the worst of the storm hit. He heard the tornado warning.
“About two minutes after that, there it was,” he said.
In Brevard County, a tornado that started as a waterspout in the Banana River whacked a mobile home park on Merritt Island on Monday. The weather service in Melbourne confirmed the damage was consistent with a low-end tornado.
In far western Martin County, weather service meteorologists confirmed an EF-0 tornado took part of a barn’s roof off and caused minor damage to a screened porch.
The soupy swirl of low pressure hugging Florida’s west coast was given a 30 percent chance of developing into a tropical or subtropical system over the next five days as it heads north into the Panhandle.
Another 5 inches is possible through Saturday morning.
“They’ll be some peaks of sun here and there,” said Chris Fisher, a meteorologist with the NWS in Miami. “It’s hard to pin down a rain estimate, but, areawide, it could be another 3-5 inches through the end of the week.”
In the 24-hour period ending at 6:45 a.m., the most rain fell north of Lake Okeechobee, where water managers were forced to close a lock to boat traffic it could keep it open for flood control.
