MIAMI, Florida - The risk for minor to moderate coastal flooding near times of enhanced astronomical high tides  (King tides) around September's Full Moon will be possible through at least Friday afternoon for Palm Beach, Broward, Collier, Monroe, and Miami-Dade counties, according to the National Weather Service in Miami.

In addition to potential for salt water inundation, there is potential for heavy rainfall and localized flooding with any slow-moving storms today.

There is also the potential of waterspouts across South Florida waters today.

Widespread showers and thunderstorms are expected this afternoon and evening across South Florida on Thursday, September 19, 2024, according to the National Weather Service Storm Prediction Center.

The thunderstorms may bring relief from the excessive heat where peak heat index values of 100 to 105 degrees will be possible from late morning into the afternoon across most of South Florida.

There is a moderate risk for rip currents along the Palm Beaches today.

Friday through Wednesday

Scattered thunderstorms will be possible daily, with primary threats of gusty winds, frequent lightning, and heavy downpours.

Minor coastal flooding will also be possible during high tide cycles throughout the weekend due to the combination of northerly swell and king tides.

An elevated risk of rip currents will continue across the Palm Beaches through the weekend.
