Winds in excess of 45 mph are possible with this storm, which is producing torrential rainfall and may lead to flooding.

Additional rainfall is expected throughout the afternoon – primarily between 1 and 7 p.m. – along with the rest of the week. A large area of deep tropical moisture will continue to stream northward across South Florida through the weekend. This will result in periods of moderate to heavy rainfall. Flooding could occur.

Heavy rain is expected in southern Palm Beach County around 1 p.m. and it will continue moving up into metropolitan West Palm Beach by 2 p.m.

And the rain isn’t going to let up. There is a 40 percent chance or higher for each of the next seven days in South Florida along with a high risk of lightning today through Monday.

In Palm Beach County, some areas have received up to 3 inches of rain in the past 6 days. In Broward and west Miami Dade counties, some spots have received 6 inches of rain in that span.

This afternoon, most of the showers and thunderstorms will be moving from the southwest to the northeast, a similar path of a strong cell that developed late Thursday.  High temperatures will in the low to mid-80s. Breezy winds out of the southeast.  Rain chances will continue into the early evening hours.

“Lightning obviously is a big concern,” said National Weather Service lead forecaster Robert Garcia. “We might also have some hail and conditions are ripe for funnel clouds and water spouts. That’s not out of the question. This is very reflective of the summertime pattern.”

Garcia said the afternoon rain is from a massive amount of tropical moisture in the Gulf of Mexico that is slowly moving.

“We might have some storms right on top of each other which could cause some localized flooding,” Garcia said of this afternoon.

 

Tonight, isolated rainfall, but not as heavy, is possible.  Low temperatures will be in the low 70s.
