Heat advisory issued by NWS Jacksonville for high heat index values up to 110 in parts of Florida and Georgia.

Floridians are sweating through the hottest stretch of the summer so far, with Heat Advisories covering much of the state and heat indices soaring to as high as 110 degrees.

While a tropical disturbance in the Atlantic is being monitored by the National Hurricane Center, its chances of developing are low — just 10%. The real danger? A relentless heat dome spreading across the Sunshine State and much of the Deep South.

The chances for a scattered area of showers and thunderstorms to develop into something more increased overnight, but remain low, forecasters said.

When the heat index climbs, so should our caution. A beach day, backyard BBQ, or even a walk around the block can turn dangerous without proper hydration.
