Gusty wind, rain, cooler temperatures and possibly even snow could affect portions of San Diego County Nov. 3 as a deep low pressure trough continues to move through the region.
Along the coast, light winds and highs of 67 to 72 degrees are expected, along with a chance of rain. A chance of showers and thunderstorms is also in the forecast for the valleys, as are highs of 65 to 70 degrees. In the deserts, highs will be 73 to 78 degrees amid a slight chance of showers.
In a period ending at 1 a.m., peak wind gusts of 60 miles per hour were recorded on Volcan Mountain and on Boucher Hill, according to the National Weather Service.
Winds of 25 to 40 mph were forecast for the NWS wind advisory period, along with gusts of up to 65 mph in the most wind-prone areas like the Interstate 8 passes.
“Strong westerly winds will continue until around sunrise near and below the passes and on the desert slopes, then slowly weaken later this morning,” according to the weather service. “Advisory strength winds are no longer expected over the high deserts. However, gusty and erratic winds will continue across the lower deserts.”
Forecasters said the wind may lead to hazardous travel conditions and lower visibility due to blowing dust along area roadways. Affected areas could include parts of Interstate 8.
Also in the mountains, there is a chance of rain this morning and a slight chance for rain and thunderstorms this afternoon. High temperatures in the mountains are forecast to be 54 to 64 degrees.
“A low pressure trough in the upper atmosphere will make slow progress across the state through tonight keeping the weather cool with periods of showers and isolated thunderstorms,” according to the weather service. “The strong winds over the mountains and locally into the deserts will gradually weaken this morning but the threat of showers will continue into Wednesday morning before the trough moves on to the east.”
