United States — Millions of Americans are being urged to prepare for a dangerous stretch of extreme heat as forecasters warn that temperatures climbing above 100 degrees could impact large portions of the Southeast before expanding into other regions early next week.
The National Weather Service (NWS) has issued an Extreme HeatRisk alert for several states beginning Sunday, with weather conditions expected to remain hazardous through at least Tuesday.
Meteorologists say the combination of scorching daytime temperatures and unusually warm nights could significantly increase the risk of heat-related illnesses, especially for people without access to air conditioning or adequate hydration.
Five States Face Highest Heat Risk
According to the National Weather Service, the highest level of heat concern on Sunday is expected across portions of:
- Texas
- Louisiana
- Florida
- Georgia
- South Carolina
Forecasters warn that some communities could experience temperatures exceeding 100 degrees, while heat index values may climb even higher because of humidity.
Officials also emphasized that overnight temperatures may remain unusually warm, offering little opportunity for people or buildings to cool down.
“Areas of Major Heat Risk will expand into the Midwest Sunday through Tuesday with pockets of Extreme HeatRisk possible, particularly through the Mississippi Valley. This level of heat will affect anyone without adequate cooling or hydration.”
The weather agency also noted that overnight lows may remain in the upper 70s and lower 80s, with some locations potentially setting record warm minimum temperatures.
Heat Wave Expected to Expand Early Next Week
Forecasters say the dangerous heat will not remain confined to the Southeast.
By Monday and Tuesday, the area experiencing extreme heat is expected to spread northward into portions of the Midwest, Mississippi Valley, and Great Lakes.
The expanding heat dome could expose millions more Americans to prolonged periods of dangerous temperatures.
Weather experts warn that consecutive days of excessive heat, combined with limited nighttime cooling, can increase health risks, particularly for older adults, young children, outdoor workers, and individuals with chronic medical conditions.
Officials Urge Residents to Take Precautions
Emergency preparedness officials are encouraging residents to make plans before temperatures peak.
Among the recommendations are:
- Drink plenty of water throughout the day.
- Spend time in air-conditioned buildings whenever possible.
- Wear lightweight, loose-fitting, light-colored clothing.
- Avoid strenuous outdoor work during the hottest part of the day.
- Take cool showers or baths to lower body temperature.
- Check on elderly relatives, neighbors, and others who may be vulnerable.
Officials also stress that electric fans alone should not be relied upon as the primary cooling method during periods of extreme heat, particularly when temperatures reach dangerous levels.
Residents without home air conditioning are encouraged to identify nearby cooling centers, libraries, shopping malls, or other public buildings where they can safely escape the heat.
Don’t Forget Pets and Vehicle Safety
Emergency officials are also reminding families to protect pets and children during periods of extreme heat.
Authorities urge people to never leave children or animals inside parked vehicles, even for a short time, as temperatures inside a vehicle can rise rapidly to life-threatening levels.
Pet owners should ensure animals have constant access to fresh water, shaded areas, and avoid walking them on hot pavement that can burn their paws.
Officials also advise residents to prepare for the possibility of power outages by knowing where they can go if electricity is interrupted during the heat wave.
Heat-Related Illnesses Can Develop Quickly
Health officials warn that prolonged exposure to extreme temperatures can lead to heat cramps, heat exhaustion, and heat stroke, with heat stroke considered a life-threatening medical emergency.
Anyone experiencing confusion, loss of consciousness, a high body temperature, or difficulty cooling down should seek immediate medical attention.
With dangerous heat expected to continue into next week, forecasters encourage residents to stay informed by monitoring local weather forecasts and following guidance from emergency management officials.
