Florida Swelters: Heat Index to Hit 110 Degrees

Florida is currently facing a dangerous heat wave with extreme temperatures and high humidity expected to persist through the weekend and into next week. Heat indices are forecast to reach up to 110 degrees in some areas, prompting the National Weather Service to issue heat advisories for 31 counties on July 8.

The intense heat is projected to last until July 17, with overnight temperatures offering little relief, remaining in the upper 70s to lower 80s. A heat advisory is issued by the National Weather Service within 12 hours of extreme heat onset. In Florida, this typically occurs when the heat index is expected to reach 108 to 112 degrees, though Miami-Dade County has a lower threshold of 105 degrees.

Adding to the conditions, a plume of Saharan dust is expected to move into Florida mid-week, potentially reducing chances for showers and thunderstorms. This dust, primarily over the Florida peninsula on Thursday, July 9, may cause hazy conditions but is expected to remain aloft. The dust should begin to dissipate by the end of the week, allowing for a gradual return of moisture and rain chances.
