Health officials urge people to stay indoors during the hottest hours of the day. A heat advisory is in effect until 8 p.m. May 31.
Temperatures are expected to reach 90 by noon today, and feel closer to the mid 90's by this afternoon. Tuesday, temperatures will increase further, and with the humidity, it will feel like 100 to 105 degrees.
Health officials recommend people stay indoors in air-conditioning, or seek out air conditioned public places including malls and movie theaters. If you are going outside, wear loose-fitting, light-colored clothing, and drink plenty of fluids to stay hydrated.
??As with any heat wave, the elderly, children, and pets are those most at risk today and tomorrow. Officials encourage people to check on their relatives and neighbors.
For those looking for a fun way to beat the heat outdoors, District of Columbia pool facilities are open today until 6 p.m.
The Washington Humane Society is also reminding pet owners to pay special attention to their animals during this kind of heat. Stephanie Shain, Chief Operations Officer for the Washington Humane Society, says pets really are quite vulnerable in this kind of heat.
"I think a lot of times people feel that the dog will be fine, or they will know how to keep themselves cool," she says. "And they really depend on us to provide that for them. We can't expect them to understand what to do when it gets really hot out."
Shain says while pets may instinctively seek out shade or drink water, people need to make sure they have access to those things. And she says bringing pets inside where there's air conditioning or a fan is the best way to keep them cool.
"One of the simplest things to remember is if it feels too hot for you then it's too hot for your pet," she says.
Shain recommends walks or exercise for pets in the early mornings and evenings to minimize exposure to the heat.
And she says never leave your pet closed in a hot vehicle. "A car is like an oven on a day like this," she says. "Absolutely do not leave your pet in a car, even with the windows cracked. It heats up there in a matter of minutes to very dangerous levels."
