The National Weather Service is warning about the prospects of a hot week ahead for a large part of the country, with the combination of heat and humidity making it feel like 100 degrees or hotter outside.
Ridging across New Mexico and portions of the Southwest will keep that region hot through Monday, with daily record highs being approached if not exceeded in a few locations. Heat Advisories and Excessive Heat Warnings are in effect from near El Paso, Texas westward into the Desert Southwest, where the probabilities of high temperatures of 100F+ are greatest. For the deserts, high temperatures in the 110s — with Death Valley threatening 120F — are anticipated.
“Staying hydrated, limiting outdoor exposure and wearing light-colored clothing when you do, and staying in air conditioned places remain the best ways to survive the heat,” advises the National Weather Service.
On Tuesday, a front developing as it drops through the Great Basin should allow for less extreme heat, though for just one day. Beyond then, the heat will push east into the Southeast and Mid Atlantic.
By Thursday, the daily maximum heat index could approach 100 in places like Philadelphia, Pennsylvania, New York City, New York, and Hartford, Connecticut. Heat indexes over 105-110 are possible too in much of northern Florida and southern Texas.
A Heat Advisory means that a period of hot and humid conditions are expected. The combination of hot temperatures and higher humidity will combine to create a situation in which heat illnesses are possible. The National Weather Service encourages people in these areas to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. They also urge people to take extra precautions if they work or spend time outside, suggesting that people reschedule any strenuous activities to early morning or evening. To reduce risk during outdoor work, the Occupational Safety & Health Administration (OSHA) recommends scheduling frequent rest breaks in shaded or air conditioned environments.
People in and around these heat advisories should 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. Do not forget about your pets. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency: call 911 if you know someone suffering.
