Map shows the very best forecast heat index level on Friday.
About 10.4 million people — 3 percent of the population of the contiguous United States — live within the areas expected to have dangerous levels of warmth.
The warmth index is a measure of how hot it really feels outside, making an allowance for humidity together with temperature. The measurement is used to point when the extent of warmth is dangerous for the human body while within the shade. When out within the sun, an individual could perceive that temperature as being higher by as much as 15 degrees Fahrenheit (8.3 degrees Celsius).
Risks related to heat index levels
Caution
Fatigue is feasible after long exposure or exercise.
A heat index of 80 to 90 degrees Fahrenheit
Extreme caution
Possible risk of warmth stroke, heat cramps or heat exhaustion after long exposure or exercise.
90 to 103 degrees
Danger
Heat cramps or heat exhaustion is probably going. After long exposure or exercise, heat stroke can also be possible.
103 to 125 degrees
Extreme Danger
Heat stroke is extremely likely.
125 degrees or higher
Risk level definitions are from NOAA.
A whole bunch of individuals die from extreme heat in america every 12 months. On hot days, the National Weather Service recommends that individuals drink fluids, stay in cooler rooms, keep out of the sun and check out relatives and neighbors, especially older people and those that live alone.

Values shown represent the very best forecast heat index level for every day. Forecast data is as of 9:04 a.m. on Sept. 23, 2022.
The week ahead across the nation
While next-day forecasts may be quite accurate, forecasts grow to be less reliable the further into the longer term they predict. Over the following week, dangerous levels of warmth are expected within the South and West.

Summer temperatures have grow to be hotter and more extreme in recent a long time, and the health effects of maximum heat may be severe.
Methodology
Maps on this page are as of 9:04 a.m. on Sept. 23, 2022, using data from the National Oceanic and Atmospheric Administration. All data shown are forecasts, including maps for the date of publication.
The very best forecast heat index is calculated using all available hourly forecasts for every day published by the NOAA. For some days further in the longer term, forecasts are published only every three or six hours. Which means that the very best forecast heat index numbers are more accurate for probably the most recent maps.
Population calculations are based on census tract population centers from the U.S. Census Bureau. Tracts are determined to be prone to dangerous heat if the population center of the tract is forecast to be exposed to a heat index of 103 degrees Fahrenheit or more.
