Nice Start to the Week — Near-record Heat Tomorrow

Posted at 10 a.m.

It’s been a nice week weather-wise in Fairfax County. Temperatures have been warm, but hey — it’s August.

Summer wants to remind us that it’s still here and temperatures today will rise to near 90°F (Fahrenheit). Tomorrow it will be mostly sunny with a high near 94° — but the combination of heat and humidity may push heat indices to between 100° and 105° degrees Friday afternoon and early evening.

During extremely hot days, there is plenty you can do to stay cool; resting for just two hours in air conditioning can significantly reduce heat-related illnesses. Take in a movie, stroll through a shopping center or visit one of the Fairfax County Cooling Centers.

Also, please remember — Never leave a pet or child in a parked car.

Don’t Leave Kids or Pets Unattended in Vehicles

Look before you lock -- don't leave children or pets unattended in vehicles

Posted at 10 a.m.

Every summer there seems to be a heartbreaking story of a child who was accidentally left in a hot car.

Heatstroke is one of the leading causes of death among children. Unfortunately, even great parents can forget a child in the back seat. Other risk factors include caregivers who aren’t used to driving kids or whose routine suddenly changes. So remember — look before you lock. Always check the back seats of your vehicle before your lock it and walk away.

You can also keep a stuffed animal or other memento in your child’s car seat when it’s empty, and move it to the front seat as a visual reminder when your child is in the back seat. And if someone else is driving your child, or your daily routine has been altered, always check to make sure your child has arrived safely.

Want to see why it’s so critically important to take these steps? Watch this video to see how quickly the temperature can rise inside a vehicle.

Multi-Day Heat Wave to Bring Excessive Heat

Posted at 11:55 a.m.heat

The National Weather Service is forecasting a multiple day heat wave Friday, July 22 through Monday, July 25. You should expect excessive heat with temperatures in the upper 90s with heat indices at or above 105°F (Fahrenheit). The hottest days appear to be Saturday, July 23 and Sunday, July 24 when heat indices could approach 110°F.

A heat dome will build over the region from the Midwest and cause temperatures to soar into the upper 90s and may reach 100°F. This, when combined with high humidity, will create dangerous heat indices exceeding 105°F.

Please use caution this weekend and remember these heat safety tips:

  • Never leave children or pets alone in a closed vehicle.
  • Drink plenty of fluids: Drink two to four glasses of cool fluids each hour.
    • Your body needs water to keep cool. Drink water even if you don’t feel thirsty.
    • Do not drink caffeinated or alcoholic beverages because they dehydrate the body.
  • Keep cool indoors: If you can, stay in an air-conditioned area.
    • Ensure your home’s cooling system is working properly before it is truly needed.
    • Resting for just two hours in air conditioning can significantly reduce heat-related illnesses.
    • Consider spending the warmest part of the day in public buildings such as libraries, schools, movie theaters, shopping malls and other community facilities, including the county’s cooling centers.
    • Electric fans may provide comfort, but with temperatures in the 90s, fans will not prevent heat-related illness.
  • Avoid strenuous physical activities or reschedule outdoor activities for the coolest part of the day, usually the early morning. Limit physical activity until your body adjusts to the heat.
  • Wear sunscreen to prevent sunburn. Sunburn makes it more difficult for your body to cool off.
    • Wear light-colored clothing, which helps reflect sunlight.
  • Eat light meals, avoiding high-protein foods because they increase metabolic heat.
  • Don’t take salt tablets unless directed by a physician.
