An unusual winter heat wave will hit truckers in Southern California the rest of the week.
A strong ridge of high pressure, plus persistent dry offshore winds, will allow afternoon highs to reach the 80s to 90 degrees in parts of the Los Angeles and San Diego areas. This is 15 to 25 degrees above normal for early to mid-February, flirting with record highs.
Besides daily records possibly being tied or broken, Los Angeles’ all-time February high of 92 degrees may be in jeopardy. This record has stood since Feb. 3, 1963.
The National Weather Service has issued heat advisories for places such as downtown Los Angeles, Riverside, San Bernardino, Ontario, Fontana, Rancho Cucamonga, Corona, Santa Ana, Anaheim, Irvine, Fullerton, Mission Viejo, Northridge, Burbank, Malibu, Santa Monica, Beverly Hills, Hollywood, Long Beach, Pasadena, San Gabriel and Pomona. These areas could see some of the hottest temperatures of 85 to 90 degrees Wednesday through Sunday.
To be on the safe side, truckers should stay out of the sun as much as possible and drink plenty of water. For flatbed drivers who have to spend time outside tarping and tying down loads in the heat advisory locations, wearing light-colored, loose-fitting clothes can help reduce the chance of heat illness.
Along with the heat will come the return of Santa Ana winds. These are dry offshore winds that flow from the Great Basin toward Southern California. These gusts will hit 40 to 55 mph Wednesday and Thursday, increasing the risk of rollovers and periodic dust storms.
