Heat advisories will be issued on Monday and Tuesday with feels like temps as high as 105 to 112 degrees.

Saharan dust and drier air aloft will help suppress our typical afternoon thunderstorms, leaving most communities dry with little rain-cooled relief from the heat. Only an isolated shower or storm is expected.

Moisture starts to gradually move back in on Tuesday. The highest coverage of storms will be across the Treasure Coast at 40% with a 20% chance of storms for the Palm Beaches.

As the ridge starts to weaken late in the week - temps will drop a few degrees. However - it will still be steamy with highs in the low 90s.

The Atlantic basin is quiet. The National Hurricane Center expects no tropical cyclone formation in the Atlantic during the next seven days.

Boating conditions look great with seas 1-2 feet and a light chop on the Intracoastal.
