Thunderstorms will roll through the Aventura area every afternoon through Labor Day, with heat indices climbing as high as 108 degrees and storm chances reaching 80 percent.
Meteorologist Calls Pattern Hot, Humid and Unsettled
WSVN Channel 7 meteorologist Vivian Gonzalez described South Florida as hot, humid and unsettled heading into the long holiday weekend in her Thursday, Sept. 3, forecast. She expects daily rounds of showers and thunderstorms through Monday, Sept. 7.
Feels-Like Temperatures Could Top 100 Degrees
Highs will stay in the lower 90s, but feels-like temperatures could hit 100 to 105 degrees on Friday and 103 to 108 degrees over the weekend, according to Gonzalez. Heavy downpours, lightning, gusty winds and localized flooding are all possible each day.
Storm Chances Climb to 80 Percent for the Holiday
The Miami Herald reported that the National Weather Service in Miami puts storm chances at 70 percent on Friday and 80 percent on Saturday, Sunday and Labor Day Monday. The worst hours for storms fall between 2 and 7 p.m.
Mornings Offer Better Window for Outdoor Plans
Gonzalez noted that it will not rain all day everywhere, and that earlier hours should give residents a drier stretch for outdoor plans.
NBC 6's forecast showed Saturday, Sunday and Monday as nearly identical: a 40 percent chance of rain in the morning and 70 percent by midday and afternoon, with highs around 91 degrees.
Flood Advisories, Marginal Rainfall Risk Already Underway
The Weather Prediction Center placed South Florida under a Level 1 marginal risk of excessive heavy rainfall on Thursday, Sept. 3, CBS Miami reported on X. Wednesday, Sept. 2, brought multiple flood advisories across the region, according to NBC 6.
Boaters Face Manageable Seas but Storm Risk
Gonzalez said seas should stay around 2 feet or less through Friday, with winds manageable overall. Thunderstorms remain the main hazard on the water, capable of producing lightning, sudden gusts and briefly rough conditions.
"Keep the umbrella handy and have a backup plan for outdoor activities as the stormy summertime pattern continues through the long weekend," Gonzalez wrote.
