A heat advisory is in effect for Miami-Dade and Broward counties on Tuesday, July 7, as temperatures across South Florida are expected to feel as high as 110 degrees.
The National Weather Service Miami issued the advisory from 11 a.m. to 6 p.m. for areas including Miami, Fort Lauderdale, and Homestead, as well as parts of Collier County. Officials warned that advisory-level heat conditions are expected to continue throughout the week, with additional advisories possible Wednesday and Thursday.
Maximum heat indices, or “feels-like” temperatures, are expected to range between 105 and 110 degrees each afternoon across South Florida. Forecasters said there is also a 40% to 60% chance that heat indices could exceed 110 degrees late this weekend into next week.
The combination of high temperatures, lower rainfall, and high pressure moving in from the Atlantic is expected to push temperatures into the mid-90s during the second half of the week.
A large plume of Saharan dust moving across Florida is also expected to reduce rain chances beginning Wednesday and continuing through the weekend. A second round of dust could further limit rainfall in the region.
Scattered showers and thunderstorms remain possible Tuesday, with the greatest chance of storms developing along the sea breeze during the early afternoon before moving inland later in the day. Forecasters said storm coverage is not expected to be as widespread as Monday, but some storms could bring heavy rainfall, gusty winds, and dangerous lightning.
The National Weather Service is urging residents to take precautions during the extreme heat, including drinking water before becoming thirsty, wearing lightweight clothing, taking breaks in shaded areas or air-conditioned buildings, and limiting strenuous outdoor activities during the afternoon.
Fans may provide some relief but may not be enough to prevent heat-related illness during periods of extreme heat, officials said.
Meanwhile, tropical activity in the Atlantic remains quiet. The National Hurricane Center is forecasting no tropical development over the next seven days, with Saharan dust, dry air, and wind shear limiting storm formation. Forecasters said current long-range models show no signs of tropical development, with the next storm name on the Atlantic list being Bertha.
