Temperatures in parts of northern California could reach 115 degrees this week as authorities warn residents to prepare for excessive heat that could be record-breaking and pose a significant hazard.
An excessive heat warning is in place through Friday for the northern Sacramento Valley and adjacent foothills, which include Redding and Red Bluff, with high temperatures forecast from 100 to 113 degrees. In Trinity County, where the National Weather Service has warned of “dangerously hot conditions,” temperatures could reach 115.
“Tomorrow and Friday are especially hot,” said Anna Wanless, a meteorologist with the weather service’s Sacramento office, on Wednesday. “And another reason we’re concerned about the heat is that there won’t be much cooling overnight.”
Nighttime low temperatures are expected to only dip into the low 80s or 70s Thursday through Friday, Wanless said, which doesn’t give the body much time to cool down and can be dangerous.
“Stay hydrated, stay in the air conditioning if you can,” Wanless said. “It will be particularly dangerous for these vulnerable populations, the elderly [and] kids… so watch your neighbors.
The northern Sacramento Valley is typically warm this time of year, often around 100 degrees, but Wanless said the heat forecast for Thursday and Friday was out of the ordinary.
There is a “record-breaking opportunity in Redding,” Wanless said. “The high temperature predicted for Redding [on Thursday] is 113, and that’s actually the record we have for that date.
The heat wave hitting Northern California is caused by the same high pressure ridge that brought extremely high temperatures to the Pacific Northwest this week.
Oregon Governor Kate Brown declared a state of emergency for much of her state on Tuesday, warning that extreme heat could cause utility outages and other disruptions. Temperatures are not expected to cool in western Oregon and Washington until the weekend.
The National Weather Service also issued an excessive heat warning through Saturday for most of Siskiyou County in northern California, as well as Josephine and Jackson counties in southern Oregon, warning of “dangerously hot daily high temperatures” of 100 to 110 degrees in the valleys.
Much of northeastern California – including Susanville and Cedarville – and parts of western Nevada are under a heat advisory Thursday through Saturday, with the National Weather Service warning that daytime highs are reaching 99 at 104.
