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.

Newsweek reached out for comment to NWS via email on Monday.

"The coolest day of the week will probably be Monday," NWS Miami meteorologist Sammy Hadi told The Palm Beach Post. "By Wednesday, most of us will be dry and hot with plenty of humidity in the very low part of the atmosphere."

CDC's website offers tips for those in areas experiencing high heat, including wearing clothes that are lightweight and loose-fitting, drinking enough water to stay hydrated, staying in indoor air-conditioned areas wherever possible and limiting physical activity.

A study released last week by the Workers Compensation Research Institute found that excessive heat leads to a significant increase in workplace injuries, including heat exhaustion and incidents like "falling off a ladder on a hot day."

When temperatures rise above 90 degrees, the study found that work-related accidents increase between 5 and 8 percent when compared to days with temperatures between 65 and 70 degrees.

The effect was greater in the Southern U.S.—including Florida—where accidents increased between 9 and 11 percent in high heat. For those working in construction, a 14-20 percent increase was seen.

Less than one month before the study was released, Florida Governor Ron DeSantis signed into law a bill that prevents local governments from requiring employers to protect workers from high heat with measures like mandatory water breaks.

Proponents of the bill argued that allowing governments to protect workers from the weather was bad for business and warned that regulations would be inconsistent across the state.
