Marine Weather and Tide Forecast for Iona, FL

DISCUSSION
Issued at 220 PM EDT Sun Apr 19 2026 High pressure aloft continues over the Gulf this afternoon while surface high pressure shifts south as a weak frontal boundary moves into northern Florida. This boundary will move across the region tonight into tomorrow morning, with a very slight increase in moisture leading to some additional clouds and a few light showers.
Winds behind the front will increase out of the north/northeast as high pressure moves into the southeast. Temperatures across the local area will be closer to normal through most of the week, with dry conditions also continuing.

AVIATION
(00Z TAFS)
Issued at 751 PM EDT Sun Apr 19 2026

A weak cold front will push across the region tonight and this will allow breezy northeasterly winds to develop overnight into Monday with gusts reaching around 25 kts or more tomorrow.
Limited moisture associated with the frontal boundary should prevent SHRA development overnight but a few showers may occur around SWFL terminals late afternoon or evening on Monday.
However, any shower activity that develops should be light with VFR conditions generally expected to prevail throughout the period.

MARINE
Issued at 220 PM EDT Sun Apr 19 2026 A weak cold front will move through the waters late today and tonight, with increasing winds and seas to start the week. A Small Craft Advisory is in effect tonight into Tuesday, but breezy northeast to east winds will continue into midweek. Winds and seas will subside for the second half of the week.

FIRE WEATHER
Issued at 220 PM EDT Sun Apr 19 2026 High pressure ridging over the region will keep rain-free conditions over the area through tonight. The next chance of any rainfall arrives Monday afternoon as some moisture moves in behind a weak cold front, but these rain chances will be limited to the southern interior and southwest Florida. Dry air with some critical relative humidity values are expected to overspread the area Monday afternoon, and this combined with breezy northeast winds will produce some hazardous fire weather conditions, primarily across the Nature Coast. A Fire Weather Watch continues for Levy County for Monday afternoon into Monday evening. More critical relative humidity values and breezy northeast to east winds are expected for Tuesday.
