The National Weather Service issued a heat advisory today until 8 p.m. on Thursday, the continuation of a week-long heat wave broiling the southern sections of the state.
The NWS said heat index values in portions of southeast, southern and southwest Florida could range from 105 —110 degrees across the area.
The heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature. There is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
The forecast for today and tonight includes isolated thunderstorms possible this afternoon over the interior areas of South Florida with the main hazards heavy downpours and lightning strikes.
The NWS said that heat index values will remain high throughout the rest of the week and into the upcoming weekend. These values will range between 105 and 110 each afternoon and early evening with some localized areas having heat indices exceed 110 degrees.
The chances of showers and thunderstorms will gradually increase through the rest of the week and into the upcoming weekend. A few of the thunderstorms could become strong and they could contain gusty winds and heavy downpours especially over the interior sections.
Areas impacted include Glades and Hendry counties, coastal and inland Collier County and most points directly east and south, including the cities of Muse, Ortona, Palmdale, Lakeport, Moore Haven, Brighton Seminole, Buckhead Ridge, Felda, Hendry Correctional, Clewiston, Lion Country Safari Park, Wellington, Belle Glade, East Naples, Naples, Marco Island, Marco Island Airport, Royal Palm Hammock, North Naples, Golden Gate, Orange Tree, Bunker Hill, Immokalee, Miles City, Sunniland, and the Miccosukee Indian Reservation.
