- Hazardous marine conditions continue today for both the Atlantic and Gulf waters.
- High risk of rip currents continues for the Atlantic beaches, and will likely last at least into early next week. In addition, high surf conditions continue for the Palm Beaches.
- Minor coastal flooding expected to begin today around high tide along the east coast. Moderate to potentially major coastal flooding is possible this weekend.
- Heavy rain, isolated flash flooding, and windy conditions are forecast for this weekend.
Short Term
(Today through Thursday) Issued at 100 AM EDT Wed Oct 21 2026
Surface high pressure will remain to our north today and Thursday. At the upper levels, height falls will continue as a trough builds across the state and the ridge over the middle of the country starts to nose eastward. Mainly dry conditions are expected the next couple of days, with plenty of dry air in the mid and upper levels of the atmosphere. Just enough low level moisture will be in place for occasional coastal showers across the east coast metro, especially during the evening and overnight hours.
High temps today and Thursday will be in the low to middle 80s for most, with some upper 80s over SW FL. Low temps tonight will range from the middle 60s around the lake to the lower 70s near the Atlantic coast.
Long Term
(Thursday night through Tuesday) Issued at 208 AM EDT Wed Oct 21 2026
Forecast gets interesting as we head into the weekend and into early next week. A 500 mb low will form in the vicinity of Cuba and strong surface high pressure will be in place over the northeast US. Deep moisture will be in place over SE FL for multiple days with PWAT values increasing to 1.8-2.0 inches. Rounds of heavy rainfall appear likely especially on Saturday and Sunday, but may continue into Monday as well. Mean rainfall totals from Friday through Monday show 3-6 inches for the east coast metro, with worst case scenario values over 10 inches possible. Given the peak of the current king tide cycle is also this weekend, the potential exists for some serious flooding concerns across the metro and other poor drainage locations along the coast. Should the forecast remain the same over the coming days, Flood headlines would be very likely.
In addition to the heavy rain threat, the tightening of the pressure gradient this weekend across FL will result in breezy NE winds, with gusts of 30-40 mph likely, especially along the coast.
Conditions will improve for Tuesday into mid week as the upper low opens up and lifts up to the northeast and drier air moves back into the area.
Temperatures during the extended period will see high temps in the low to mid 80s each day and lows in the 60s/70s.
Aviation
(06Z TAFS) Issued at 100 AM EDT Wed Oct 21 2026
Mainly VFR conditions today with light NW winds this morning becoming NE 10-15 kts after 15Z. Some occasional coastal showers are possible late in the day.
