As a blistering heat wave sweeps across the Southwest, U.S. officials are telling residents in three major states to stay inside. The warnings come as temperatures are forecast to reach between 105 and 110 degrees Fahrenheit on Tuesday, May 12.
An extreme heat warning has been issued for one of the states, while the other two are under a major heat advisory. The affected states are California, Arizona, and Texas. The areas of greatest concern include central California, the Palo Duro Canyon region in Texas, and the Phoenix metropolitan area in Arizona.
“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” the warning states. “Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke.”
Officials are also warning about the possibility of extreme winds accompanying the heat, which could create additional hazards for residents. The combination of high temperatures and strong winds can lead to rapidly changing conditions and increased fire risk.
The heat wave is part of a larger pattern of extreme weather affecting the United States. Just last month, an arctic blast in May prompted federal warnings for four states, illustrating the dramatic swings in weather the country can experience.
For those without air conditioning, officials recommend finding a cooling center, taking cool showers or baths, and using the oven less to keep indoor temperatures down. It's also important to never leave people or pets in a closed car, even for a short time.
Outdoor workers are at particular risk. The Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air-conditioned environments. Anyone overcome by heat should be moved to a cool, shaded location, and heat stroke is considered a medical emergency—call 911 immediately.
Residents are also reminded to check on family members, older adults, and neighbors, and to watch for signs of heat cramps, heat exhaustion, and heat stroke. Pet owners should ensure their animals have plenty of cool water and access to shade, and be aware that asphalt and dark pavement can burn pets' paws.
This heat warning comes on the heels of another scorcher alert for two states where temperatures are nearing 110°F. The repeated extreme heat events highlight the importance of being prepared for such conditions.
As the heat wave continues, the key message from officials is clear: stay inside, stay hydrated, and stay safe. With temperatures expected to remain dangerously high, it's a day to avoid the outdoors and take all necessary precautions to protect yourself and your loved ones.
