Forecasters warn of 109 heat index in South Florida

National Weather Service forecasters are cautioning that heat index temperatures could reach 109 in areas of South Florida today as the Bermuda high settles over the state.

The deep-layer pressure with east-southeast winds means showers will migrate into the center of the state, leaving the coast mostly dry and crispy.

“This potential for hot days looks plausible through much of the work week, creating a hazard for those who are outdoors for extended periods of time,” forecasters wrote this morning. “Anyone working outdoors should stay hydrated and take frequent cooling breaks to help their bodies cope with the stresses from hot temperatures this week.”

Today’s high temperatures in Palm Beach County should reach into the low 90s with overnight lows falling only to 82 degrees. There is a 20 percent chance of rain.

Saharan dust wafts into North Florida, but dry air persists into South Florida.
