A dangerous heat wave imperiling people on the West Coast is expected to peak Saturday, but experts say the health risks will persist long after temperatures crest.

“Widespread temperature records are expected to be tied or broken. Saturday will likely shape up to be the hottest day in this heatwave when high temperatures into the 110s will be common across California,” forecasters said in their nationwide update Friday. “The duration of this heat is also concerning as scorching above average temperatures are forecast to linger into next week.”

Some experts said medical risks due to heat often trail behind the rise in temperatures — but spike as the days of risk add up.

“Usually you see deaths from heat waves not from the first day, but on the second and third day,” said Dr. Lisa Patel, a clinical associate professor who practices as a pediatrician at Stanford Medicine Children’s Health. “The cumulative heat is a big risk factor, especially for the elderly and for chronic health conditions.”
