Strong Storms Moving Offshore

The line of storms which moved through the I-4 corridor this afternoon is about to exit offshore Volusia County. Mariners from Cape Canaveral northward can expect wind gusts of 30 kts or possibly greater and cloud-to-water lightning as these storms move into the Atlantic. Some showers have also developed around Okeechobee and will move off to the northeast, affecting the Treasure Coast with heavy rain and occasional lightning before moving offshore in the next couple of hours. Elsewhere, isolated to scattered showers will continue behind the line of storms.

Severe Thunderstorm Watch for Lake County until 8 pm

A Severe Thunderstorm Watch has been issues for most of West Central Florida as well as Lake County. As of 2:30 pm, a complex of thunderstorms which has been moving across the eastern Gulf of Mexico today is beginning to move onshore the Tampa area. These storms will move to the northeast toward Lake County, arriving around 4:00 pm. The main threats from these storms include wind gusts of 60+ mph and hail possibly quarter-sized or larger as well as heavy rain and lightning. The line of storms is expected to weaken as it moves across the peninsula, but an isolated threat for severe weather remains across the rest of East Central Florida through the evening as this system continues eastward.

Elsewhere, isolated small showers will continue to develop across the rest of East Central Florida this afternoon, particularly along the coast. Brief moderate to heavy rain and maybe a lightning strike or two will be the only concerns wit these showers and storms.

Storm System Moving in off Gulf of Mexico

The front edge of a system of showers and thunderstorms coming in off of the Gulf of Mexico is beginning to reach Lake County as of 12:30 pm. While the showers and storms themselves are moving toward the north northeast, the entire system is making its way east into the Florida peninsula. These showers and storms will begin to push farther into East Central Florida as the afternoon passes, but the best chance for any strong to severe storms remains later this afternoon and into the evening.

Along the East Central Florida coast, showers continue to develop across the Treasure Coast and move northward up the coast. This trend is expected to continue ahead of the large system moving in off of the Gulf. Activity will be mostly showers through mid-afternoon, but a lightning strike or two and some gusty winds are possible.

Showers and Storms along Warm Front

A low pressure system continues to develop in the eastern Gulf of Mexico with an associated warm front stretched across East Central Florida. A small line of showers and storms has developed along the warm front and is moving its way north, bringing brief moderate rainfall and a couple of lightning strikes to the Brevard and soon Volusia coastal areas and adjacent waters. South of the warm front, showers may develop through the morning and afternoon hours.

The best chance for stronger storms will be this afternoon and evening as the low moves over the northern Florida peninsula. Winds of 50 to 60 mph or greater will be possible with afternoon and evening storms, along with heavy rain, lightning, and possibly hail the size of quarters or larger.

Light rain this morning. A better chance for strong storms and heavy rain this afternoon.

At 630 AM, doppler radar showed mostly spotty light rain ahead of a warm front, which was lifting north across central Florida, as the heavier showers over the Treasure Coast had dissipated. Through mid morning, expect only light rain and sprinkles to move north across east central Florida as the front continues its northward trek over the area.

Later today, a developing area of low pressure will move northeast toward the Florida big bend. A large area of showers and storms is expected to develop and spread across the Florida peninsula ahead of the low. Heavy rainfall amounts of 1 to 3 inches, strong gusty winds in excess of 50 to 60 MPH, hail and cloud to ground lightning will be possible in storms from this afternoon into early this evening.

Heavier rain showers moving into the Treasure Coast and Lake Okeechobee Regions

At 400 AM, doppler radar showed a band of heavier showers with a few embedded lightning strikes along a warm front lifting northward across Martin County and the adjacent coastal waters. Through sunrise, this activity will spread north across Martin, Saint Lucie, Okeechobee, and Indian River Counties, producing locally heavy downpours totaling between one half and one and one half inches in some locations. This will result in local ponding of water on roads and reduced visibility for drivers. Use caution when driving in this area.

Spotty light rain and sprinkles will continue, mainly offshore

Through 430 AM, expect very light rain and sprinkles to continue offshore south of Cape Canaveral, with a few sprinkles moving onshore as far north as Melbourne Beach. Accumulating rainfall is expected to be sparse, ranging from a trace to one or two hundredths in isolated spots.
