A heat advisory is in effect for the Baton Rouge and New Orleans areas on Sunday.
The combination of high temperatures in the low to mid-90s and high humidity levels could result in heat index values between 105 and 109 degrees, according to the National Weather Service.
At that heat index level, people need to take precautions during outdoor activities against sunstroke, muscle cramps or heat exhaustion. People should drink more nonalcoholic fluids, take frequent breaks in activities and rest in shady areas when possible, according to the Centers for Disease Control and Prevention.
The advisory is in effect from 10 a.m. to 6 p.m. Sunday.
Heat index is how hot it feels outside when temperature and humidity are combined.
Isolated showers are also possible in the afternoon, the National Weather Service said.
