At 2pm, the heat index was 109° Monday afternoon; and that’s not the hottest yet today.
The National Weather Service (NWS) has issued an Excessive Heat Warning for Harris County until to 8 p.m. today. Expect peak temperatures to reach 95° with index values of possibly 113° to 117°.
Dangerously hot conditions with heat index values that high means extreme heat and humidity will also increase the chance of heat-related illness and everyone should take precautions to avoid exhaustion.
What you should do:
- Keep your body temperature cool to avoid heat-related illness.
- Always remember to LOOK BEFORE YOU LOCK for children and pets in vehicles.
- Stay in an air-conditioned building as much as possible.
- Avoid direct sunlight.
- Wear lightweight, light-colored clothing.
- Check on those most at-risk twice a day.
- Bring pets inside and provide plenty of water for them to drink.
Extreme heat for a long period may put a strain on the electric grid. To reduce strain to the grid during the peak hours of 3 p.m. to 7 p.m., it is recommended that you set your air conditioner at 78°F if possible and avoid using large appliances.
- Because your body loses fluids through sweat, you can become dehydrated during times of extreme heat.
- Drink more water than usual.
- Avoid alcohol or liquids containing high amounts of sugar.
- Remind others to drink enough water, especially when outdoors.
- Stay updated on local weather forecasts and tips from trusted partners such as National Weather Service Houston-Galveston, Harris County Public Health, and ReadyHarris.
- Learn the symptoms of heat illness.
