SAVANNAH, GA (WTOC) - The National Weather Service has issued an excessive heat warning from 11 a.m. to 8 p.m. Thursday.
High temperatures in the mid to upper 90s combined with a surge in humidity with the sea breeze will produce heat index values of 114 to 118 degrees for several hours on Thursday afternoon, according to the NWS. The most intense heat and humidity will affect areas such as Daniel Island, downtown Charleston, West Ashley, Ravenel, Beaufort, Bluffton, Savannah, Half Moon Landing and Darien.
An excessive heat warning means a prolonged period of dangerously high temperatures can be expected and the combination of heat and humidity will create a dangerous situation where heat-related illnesses are likely.
This level of heat is extremely dangerous, according to the NWS. The risk for heat-related illnesses will be especially high due to the long duration of the heat wave.
Those who go outside are urged to drink plenty of fluids, stay out of the sun and stay in air conditioning.
Avoid venturing outside if possible. Even short-term exposure to the heat will be dangerous. Those who must work outside should take frequent breaks and drink plenty of non-caffeinated and non-alcoholic fluids, wear lightweight and light-colored clothes, wear a hat and use sunscreen, according to the NWS.
