Current - Tonight
Radar has quieted significantly over the past few hours as expected with the loss of daytime heating and the fact that nearly every corner of the forecast area became worked over this afternoon. Scattered to numerous thunderstorms spread across east central FL, riding along the sea breeze and boundary collision. A few storms produced gusty winds and funnel clouds, but slow storm motion contributed to a higher focus on heavy rainfall amounts, which totaled 3-4" in isolated locations.

As of this evening, most activity has dissipated, with lingering showers and lightning strikes in the Lake Okeechobee vicinity, stretching across Martin County. These showers are expected to clear prior to midnight, leaving only a dense deck of debris cloud cover.

No changes to the current forecast, except to lower rain chances over land tonight. Lows in the mid 70s.

Marine
Tonight...(modified previous) S winds around 10 kts becoming SW overnight. Seas generally 2-3 ft but could build to 4 ft well offshore (north of Cape).
