Issued at 411am EDT Tuesday Mar 19 2024

Today - Tonight
Poor to hazardous boating conditions today. Northerly winds around 25-30 knots will begin to quickly diminish after sunrise becoming widely 5-10 kts by the evening. Seas of 6-7 ft nearshore and 8-10 ft offshore will be slower to subside into the overnight. Seas continuing to range 6-7 ft offshore by late tonight. A Small Craft Advisory remains in effect for all central Florida Atlantic waters until 11 AM, continuing for the offshore waters and the nearshore Treasure Coast until 11pm tonight.

Wednesday-Thursday...Dry conditions prevail through the day on Thursday, thanks to high pressure. Light northerly winds Wednesday morning veer onshore in the afternoon as the sea breeze develops. Then, easterly flow is forecast Thursday, with winds up to 8-12kts. Seas 2-5ft early Wednesday diminishing to 2-3ft through the period.

Thursday Night-Sunday...Winds continue to increase into Thursday night, as a low pressure system approaches the area. Southeasterly winds increase to up to 18-20kts by daybreak on Friday, then veer southerly at 20-25kts during the afternoon. Winds diminish Saturday, as they veer to northerly at around 15kts, but then increase from the north-northeast once again to around 20kts Sunday. Meanwhile, seas 4-5ft early in the period build to up to 7-11ft by Sunday. Needless to say, Small Craft Advisories look likely late this week into the weekend.

Shower chances will also begin to increase Thursday night, becoming numerous to widespread during the day on Friday. A few lightning storms cannot be ruled out. Chances diminish into Saturday, but isolated showers will remain possible over the Atlantic waters into Sunday.

Fire Weather
Issued at 411am EDT Tuesday Mar 19 2024

Today...A dry, post-frontal airmass builds southward across central Florida and min RH values fall below 45 percent across the area this afternoon. Fire weather conditions become particularly sensitive across the interior where values fall as low as 30-35 percent. Northerly winds around 10-15 mph persist through late morning before gradually diminishing into the afternoon.

Wednesday-Thursday...Sensitive fire weather conditions persist through mid-week. Very dry min RHs forecast area-wide Wednesday, falling to around 25-35% for much of the area. Portions of the Treasure Coast look to remain around 40%. Fortunately, winds will be light, with the afternoon east coast sea breeze forecast to remain around 10mph or less. Poor to fair dispersion.

By Thursday, increasing moisture will provide some improvement, but min RH will remain between 35-45% for much of the local area. However, onshore flow looks to increase from Wednesday, with afternoon winds 10-12mph. Generally good dispersion.
