Excessive heat warning issued for Miami-Dade due to sweltering temperatures

MIAMI – For the second time this month, the National Weather Service has issued an extreme heat warning for Miami-Dade County.

The extreme heat warning is in effect until 8 p.m. Friday and was issued because the NWS said that the temperature felt could reach 112 degrees. The NES issues an excessive heat warning when the heat index values, “felt” temperatures, reach 110 degrees for two hours or more.

“Extreme heat and humidity will greatly increase the chance of heat-related illness, especially for those who work or participate in outdoor activities,” the weather service said in a statement.

Miami-Dade and Broward are on a heat warning until 8:00 pm Sunday because temperatures are expected to hit 110 degrees.

The National Weather Service issues a heat alert when a heat index of 105 degrees or higher is expected for at least two hours.

To avoid exposure to heat-related illness, officials say people should:

  • Drink plenty of fluids.
  • Wear light, loose clothing.
  • Stay in an air-conditioned room if possible.
  • Avoid prolonged exposure to the sun.
  • Do not leave children and pets unattended in vehicles.

Working with County officials, the National Weather Service revised its policy on when heat advisories and extreme heat warnings are issued.
