Heavy rain and flooding risk in Florida, Saharan dust to follow

A slow-moving storm system is producing heavy rain across South Florida and the Florida Keys as of June 2, 2025, affecting areas previously under drought conditions. Rainfall is forecast to continue through June 4, with cumulative totals possibly exceeding 150 mm (6 inches) and increasing the risk of flash flooding.

The low-pressure system tapping into tropical moisture from the eastern Gulf of Mexico is expected to cause steady, heavy rain and potential urban flooding across South Florida and the Florida Keys beginning June 2 and lasting through June 4.

On June 2, rainfall across Florida ranged from 51 to 102 mm (2 to 4 inches), though some areas saw heavier totals of 203 mm (8 inches).

The stalled front will continue to interact with an upper-level trough moving into the northeastern Gulf. This interaction will lift the core of the tropical moisture northward, leading to the threat of heavy rain spreading up the Florida Peninsula.

Most of the region is expected to see around 25 to 76 mm (1 to 3 inches) of rain, with heavier pockets possibly reaching 76 to 152 mm (3 to 6 inches) in isolated areas. A Flood Watch will remain in effect through Tuesday night.

The rainfall will bring some relief as South Florida continues to face severe to extreme drought conditions. Starting Wednesday, the wet weather is expected to extend northward into North Florida and the coastal Southeast.

This shift will occur as a low-pressure system develops along a stationary front over the western Atlantic and gradually moves up from just off the northeast Florida coast.

On top of the incoming torrential rain, a thick layer of Saharan dust is forecast to drift over Florida later this week.

This natural occurrence, often seen during hurricane season, is expected to bring hazy conditions and create colorful displays in the sky at sunrise and sunset beginning June 5.
