Strong winds expected to blow through mountains and deserts

SAN DIEGO - Strong winds are expected to blow through the mountains and deserts of San Diego County this afternoon through early Saturday, especially along Interstate 8.

''A trough of low pressure moving through Nevada will bring strong onshore pressure gradients, likely resulting in gusts of 45 to 55 miles per hour along mountain ridge-tops and desert mountain slopes and extending into the lower deserts,'' according to a National Weather Service advisory. ''Winds this strong can make driving difficult, especially for high-profile vehicles -- use extra caution.'' The NWS issued a wind advisory for the mountains and deserts from 2 p.m. today to 8 a.m. Saturday.
