Red flag warnings are in effect Wednesday through Saturday evening for Southern California because the “unseasonably hot” conditions, low humidity and breezy winds are “capable of producing extreme fire behavior,” according to the National Weather Service.
Thunderstorms at the tail end of the week, from Friday to Sunday, are also possible in the region, which could trigger lightning strikes that can ignite new fires.
California Gov. Gavin Newsom moved fire engines, crews and other firefighting resources into the region to prepare for the high-risk conditions.
Los Angeles Mayor Karen Bass said Tuesday that this week’s heat wave could bring “potentially some of the hottest temperatures of the summer.” Temperatures in Los Angeles could reach 94 degrees F on Thursday and Friday.
The sweltering conditions across the western U.S. will increase the risk of heat-related illness or death. Anyone is susceptible when temperatures spike, but lingering heat waves are particularly dangerous for children, people with pre-existing health conditions, older adults and individuals who work outdoors.
The health impacts of extreme heat are a significant concern of climate-fueled heat waves.
During prolonged heat waves, weather service officials said people should stay in air conditioning, when possible, and avoid strenuous activities. Other heat safety tips include staying hydrated, wearing light clothing and checking in on family members and neighbors.
In the Southwest, blisteringly hot conditions will persist over the next several days, possibly challenging some daily temperature records.
