The National Weather Service in Melbourne is reporting the person is a male in his 30s.

One person has been killed in 2016 by lightning, according to the National Weather Service.

A 28-year-old woman was struck while sheltering in a personal tent at a blues festival in Larose, LA. Two other woman sheltering in the tent were injured and are currently hospitalized.

UPDATE 3:50 p.m. A strong thunderstorm is moving toward northeastern Palm Beach County at about 15 mph.

A special weather statement has been issued for areas that include Jupiter, Palm Beach Gardens, Tequesta and Jupiter Farms.

Winds in excess of 30 mph and half-inch hail are possible with this storm. National Weather Service forecasters said torrential rains are falling with this storm and localized flooding could occur.


UPDATE 2:55 p.m.: The Storm Prediction Center has issued an alert for the possibility of large hail and damaging winds for areas along the Atlantic coast of Florida including Palm Beach County.


The National Weather Service in Miami has also issued a special weather statement for northeastern Palm Beach County as a strong thunderstorm heads east toward Jupiter at 20 mph.

Wind gusts up to 50 mph and nickel size hail are possible with this storm. Locations impacted include Jupiter, Palm Beach Gardens, Tequesta, Juno Beach and Jupiter Farms.

There is a 20 percent chance a storm watch will be issued as the severe storms expected will be very sparse, center forecasters said.

But high dew points and temperatures in the low 80s are creating an atmosphere where air will become buoyant and begin to lift, creating thunderstorms.


UPDATE 2:05 p.m. While there is a lack of rain throghout South Florida this afternoon, the National Weather Service is still expecting heavy showers and/or thunderstorms later today into early evening.

The most recent discussion mentions outflow boundaries left over from storms that erupted this morning. Outflow boundaries are the edges of rain-cooled air that flow out form a thunderstorm’s downdraft.

The cooler air creates a pressure gradient and an outflow boundary in itself can initiate new storms depending on the difference in temperatures between the cooler air behind the outflow boundary and the surrounding environment.

At 2 p.m. it was still 82 degrees out, but the relative humidity was a balmy 77. Temperature differences are usually smaller between the environment and cold pool behind the outflow boundary when the relative humidity is high.

UPDATE 12:15 p.m.: National Weather Service meteorologists say the forecast for this afternoon remains uncertain, but the warm daytime temperatures will stir up the atmosphere and contribute to the possibility of storms.


At noon, it was 82 degrees at Palm Beach International Airport, with the high temperature expected to reach 84 degrees. The normal temperature for this time of year is 79 degrees.

The Storm Prediction Center still has Palm Beach County in its “marginal” forecast for severe weather, but has weakened the forecast some from this morning saying “anything more than a couple of strong storms appears unlikely.” There is a 5 percent chance of hail and a 5 percent chance of damaging winds.

The NWS forecast out of Miami said it still expects regional showers and thunderstorms this afternoon into early evening with a few strong thunderstorms and isolated severe thunderstorm.


Previous story: It’s going to be a stormy day in South Florida, with isolated heavy rain this morning from a diminishing squall line gusting through Palm Beach County and a second convective system near the Keys that is heading north.

That second system may not reach Palm Beach County, dying out in Miami-Dade or Broward, and there could be a lull in the storminess in the early afternoon, according to the National Weather Service in Miami.

A bigger concern may be later this afternoon. The Storm Prediction Center in Norman, Okla., has Central Florida and parts of the Atlantic coast,  including  Palm Beach County, under a marginal risk for thunderstorms.

While marginal is the lowest level category on the center’s 5-tier scale, forecasters are still concerned about some risk for organized supercell thunderstorms, including severe wind, hail, frequent lightning and “perhaps a tornado.”

The severity of storms may depend on how long morning cloudiness hangs around to keep temperatures down. With daytime heating and the afternoon sea breeze kicking up, there could be enough instability for pockets of severe storms.

In Okeechobee County yesterday, a fire rescue station reported golf ball size hail at about 5:30 p.m., according to Storm Prediction Center reports.
