The National Weather Service has issued a heat advisory, which is in effect from 1 p.m. to 8 p.m. Sunday, for the entire Washington, D.C., area.
A heat advisory means that a period of high temperatures is expected. The combination of high temperatures and high humidity will create a situation in which heat illnesses are possible.
Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible and drink plenty of water.
1. It’s going to feel like 100+ degrees.
High temperatures on Sunday will be above 90 degrees but will feel like 100 to 110 degrees due to the humidity, Storm Team4 Meteorologist Amelia Segal said.
2. Sunday is going miserable.
Segal said the feels-like temperature by 3 p.m. Sunday will range from 96 degrees in the mountains of West Virginia to 108 in downtown Washington. The DC Homeland Security and Emergency Management Agency said cooling centers will be opening once the heat index reaches 95 degrees.
3. See the Nationals v. Dodgers game.
For Sunday's, fans will be allowed to take in two one-liter, factory-sealed bottles of water instead of just one; misting fans will be placed throughout Nationals Park; and cooling centers with air conditioning and free ice water will be set up in the Roosevelt and Kennedy rooms in the conference center on the third base side of the club level.
4. Expect hot, hazy and humid afternoons.
Humidity will be at full force Sunday. Weather conditions will be most extreme in the afternoons. Plan your workouts for the morning and make sure to stay hydrated and refreshed with the perfect ice cream cone.
5. Pay attention to your air conditioning.
Due to the extreme weather, be careful with your car’s cooling system as your car will be more susceptible to overheating. Also, there will be a greater demand for electricity to run home cooling systems, so be aware of potential problems. Metrorail may also be affected. If your AC breaks down, consider diving into a public pool to keep cool.
6. Remember: It’s not just the weekend.
Monday is expected to still be humid and temperatures will remain in the low to mid 90s. There will also be a chance of afternoon storms. The heat wave will continue into Tuesday, with feel-like temps still around 100. Lower humidity on Wednesday may help drop temperatures below 90.
