Last Map Update: Sat, Jul 18, 2026 at 9:38:23 am CDT

Heat index values will climb to 105 to 110 across much of the area today with some locations likely topping out around 112.
Hot and humid conditions are expected Saturday, with peak heat index values around 105 to 110 degrees. The hottest conditions are expected near Lake Pontchartrain, so remember to stay hydrated, take breaks, and limit strenuous outdoor activity.
We're monitoring a disturbance with a 🟡 low (10%) chance to develop in the eastern Gulf in the next 48 hours and a low (30%) over the next 7 days. This system is NOT ❌ an immediate threat to our local area, but could bring locally heavy rainfall to areas of the eastern Gulf Coast. Stay tuned for future updates.
Given the last few days have already been on the toasty side and impacts from heat are an accumulating issue the heatrisk is increasing across the area. Even with heat index values possibly a degree or two lower tomorrow the heatrisk increases across the region given it will continue to be very hot and this doesn't look to change going through the first half of next week.
