Precautionary/preparedness actions

Very warm temperatures on tap again today and combined with abundant Gulf moisture the heat index readings late this morning will exceed the 102 mark and peak at 107 to 111 over the advisory area during the early to mid afternoon hours. Thunderstorms are expected to erupt in this hot and humid atmosphere across the northern portions of the area and move south bringing cooling from cloud cover and much cooler thunderstorm outflows. Some areas south of the Interstate 10 corridor may not see much relief from these high heat index readings until after 6 PM.

Precautionary/preparedness actions

A heat advisory remains in effect until 7 pm this evening.

Peak heat indices of 105 to 109 degrees are likely across the advisory area this afternoon.

Precautionary/Preparedness Actions

Heat advisory remains in effect until 8 pm Friday.

Precautionary/Preparedness Actions

If you plan to be outside, drink plenty of water hours before going outside. By being well hydrated your body will have plenty of water available for sweating to cool your body. Avoid prolonged exposure or strenuous physical activity. Drink plenty of water hours before going outside your body can lose up to a gallon of water an hour through perspiration. Drink plenty of fluids to avoid dehydration. Alcoholic and caffeinated beverages can increase the rate of water loss in your body, increasing the risk of heat exhaustion or stroke. Wear lightweight, light- colored, loose-fitting clothing. Wear a hat to shield yourself from the sun, and use a sunscreen to reduce possible sunburn.
