Who is most at risk in heat?

Starting Wednesday, Sacramento’s heat risk will be moderate, the weather service said.

The heat risk scale provides a forecast that shows the likelihood of heat-related problems occurring.

The scale calculates how hot it is compared to normal, how long the heat lasts and whether it’s likely to cause health issues based on data from the U.S. Centers for Disease Control and Prevention.

It ranges from 0, meaning there’s little or no heat risk, to 4, indicating an extreme heat risk.

These conditions will persist through Saturday, Aug. 23.

Moderate heat risk “affects most individuals sensitive to heat, especially those without effective cooling and/or adequate hydration,” the National Weather Service said.

Vulnerable individuals include those who are pregnant, newborns, children, older adults and those with a chronic illness.

These groups are more at risk due to age and conditions that make it difficult to regulate high temperatures.

“Stay in a cool place during the heat of the day,” the National Weather Service wrote on X. “If outdoors, stay hydrated, take breaks, and find shade.”
