Gusty northwest to north winds will blow across portions of southwestern California and West San Gabriel Valley through at least Friday morning, according to a Montebellow Police Department alert. Drivers were advised to use extra caution and to be prepared for sudden gusty cross winds, particularly in the northern mountain area.
The alert said weak frontal systems passing to the north of the region will continue to generate gusty northwest to north winds across portions of Southwestern California for much of the week. Authorities issued a wind advisory that will continue to be in effect until 3 p.m. Friday.
Areas of northwest to north can expect winds 20 to 30 mph with gusts 35 to 45 mph. The strong winds will continue through mid morning Friday, then winds will diminish some.
Gusty northerly winds will continue through at least early Friday morning. Wind advisories will likely need to be extended Friday into Saturday as winds become offshore.
Authorities say gusty winds will make driving difficult, especially for drivers of high profile vehicles. Major roads that will be affected include Highways 14 and 126, and Interstate 5.
While the primary affected areas will be Santa Clarity Valley, strong winds were reported Thursday afternoon along Interstate 5 impacting the cities of Monterey Park, Alhambra, Montebello and Rosemead.
