A significant weather advisory has been issued for Central Palm Beach County as thunderstorms are tracked near South Bay moving east at 20 mph.
Wind gusts up to 50 mph and funnel clouds are possible with this storm.
Cities affected include Wellington, West Palm Beach, Palm Beach Gardens, Belle Galde, South Bay and Royal Palm Beach.
The advisory is in effect until 3 p.m.
Previous story: Palm Beach County was thrashed by a deluge of showers and rapid-fire lightning Sunday as a rush of rain cooled air from thunderstorms north of Lake Okeechobee clashed between themselves and afternoon sea breezes.
Robert Molleda, the warning coordination meteorologist with the National Weather Service in Miami, said in just a 2-hour period between 7 p.m. and 9 p.m. Sunday an estimated 2,500 lightning strikes hit Palm Beach County.
“I would say certainly, that’s a lot and a lot more than your average thunderstorm day,” Molleda said.
The National Weather Service is compiling rain totals from stations throughout South Florida and should have those ready before 11 a.m.
The official weather gauge at the Palm Beach International Airport does not tell the full story.
Although it recorded wind gusts as high as 30 mph, the airport rain gauge reads that just 0.65 inches of rain fell Sunday. I live about a mile from the airport and my rain gauge collected 2.5 inches.
South Florida Water Management District measurements were as high as 2.29 at the Corbett Wildlife Management Area in western Palm Beach County.
Below are some other measurements:
Jupiter Farms, 1.34
North Palm Beach, 1.33
Royal Palm Beach, 1.30
Forest Hill School, 0.85
Boynton Beach, 0.55
Delray Beach, 0.60
Arlena Moses, a meteorologist with the NWS in Miami, said the storms focused on Palm Beach County as the outflow boundary from stronger systems to the north rushed into the area.
An outflow boundary is a flush of rain-cooled air that spreads across the land like a flood. They can interact with each other, forcing more storms to develop, or can intercept other boundaries such as South Florida’s familiar afternoon sea breezes.
Rain totals in the Kissimmee basin north of Lake Okeechobee were nearly 3 inches in many areas as the storms rolled through. It was an unusual situation for South Florida to see during this time of year when a low pressure system pushes a trough into the Sunshine State.
Moses does not think today’s storms will be as robust as what was experienced Sunday, but the Storm Prediction Center does have Palm Beach County at a marginal risk for severe weather.
