A heat advisory for Reston, Northern Virginia and the DC area is in effect from 1 to 7 p.m. as afternoon temperatures may hit 99 degrees. With the heat index, it will feel like 105, so take precautions.
A heat advisory means a period of high temperatures is expected. The combination of high heat and high humidity creates a situation in which heat illnesses are possible, says the NWS.
To avoid head exhaustion and heat stroke:
- If possible, reschedule outdoor strenuous activities to early morning or evening.
- Wear lightweight and loose-fitting clothes.
- Drink plenty of water.
Relief is in sight late in the day, when thunderstorms are expected to roll through Reston, bringing with them slightly lower temperatures for Wednesday.
