What’s the heat risk in Fresno?
The heat risk scale, or the weather service’s HeatRisk Prototype, 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 if 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.
From Wednesday through Saturday, the heat risk will be at a 3, or major, in Fresno.

Who’s at risk during extreme heat?
According to the weather service, major heat risk “affects anyone without effective cooling and/or adequate hydration.”
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.
“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” the weather service said in the warning. “Do not leave young children and pets in unattended vehicles.”
