Map Shows ‘Extreme’ Heat Risk Warning as Florida Braces

The National Weather Service (NWS) is predicting that “extreme” heat will hit South Florida this week.

NWS Miami said on Monday that heat advisories would likely be issued later in the week, with “excessive heat warnings” possible in some areas. Temperatures are expected to reach the mid-90s in large areas of South Florida on Tuesday and Wednesday

High humidity will likely mean that the heat index, or the temperature that weather “feels like,” will be closer to 110 degrees for many. NWS says that the “multi-day excessive heat event” will be “very dangerous to anyone without proper hydration or adequate cooling.”

Extreme heat causes approximately 1,220 deaths in the U.S. every year, according to the Centers for Disease Control and Prevention (CDC). Injuries can range from heat rashes and sunburns to heat exhaustion and heat stroke—a life-threatening condition that requires immediate medical attention.

Maps from NWS show the heat wave moving from southwestern Florida on Tuesday to the Miami area on Wednesday. The central part of South Florida is expected to sizzle on both days, while periods of extreme heat will be experienced far north as the Tampa Bay Area.
