SOUTHERN CALIFORNIA — The first snow of the season is expected in Southern California’s mountains Monday night, while lower elevations are bracing for cooler temperatures, strong winds and light rain, according to the National Weather Service.
“A cold low-pressure system will sweep through the region today and into Tuesday. Significant cold weather is expected by Tuesday and will continue into the second half of the week,” the NWS said Monday.
Some parts of the region experienced very light rain Monday morning, especially in southern San Diego County. Most rainfall stations recorded rainfall amounts of about one-hundredth of an inch. Another chance of rain is possible Tuesday night, mainly in interior and mountainous areas of Southern California.
Snowfall tonight is expected to drop to less than 7,000 feet in the Los Angeles County mountains and less than 5,500 feet in other parts of the region, including the San Bernardino Mountains, where light snow is possible, according to the NWS. This means that there is.
Conditions are expected to remain mostly dry in Los Angeles County, except in areas where it will snow.
Orange County and the Inland Empire are expected to see less than 0.05 inch of precipitation. Less than 0.10 inch of rain is expected along the coast of San Diego County, while as much as 0.25 inch of rain is possible in mountain slope valleys along the coast of Orange and San Diego counties.

Autumn weather began on Monday, with temperatures across the region dropping between 3 and 17 degrees compared to Sunday. The next few days are expected to remain much cooler than last week. Tuesday will be the coldest day, with temperatures expected to drop several degrees further, the Japan Meteorological Agency said.
Low temperatures will drop into the upper 40s to lower 50s along the coast overnight, with highs reaching the mid 60s by Tuesday morning.
Further inland, temperatures are expected to reach 70 degrees in Orange, Los Angeles and San Diego counties. Expect temperatures in the mid-60s to low-70s in the Inland Empire, low-to-low 60s in the high desert and mid-to-late 70s in the low desert.
Overnight low temperatures Tuesday through Wednesday are expected to reach the low 40s inland and into the upper 30s to mid-40s in the Inland Empire. Temperatures are expected to decline from the teens to mid-20s in the San Bernardino Mountains, from the low 30s to low 40s in the high desert, and from the mid-40s to low 50s in the low desert.
The cold weather could bring patchy frost to the high desert by Wednesday morning.

However, the NWS said that “high winds remain the most impactful weather element.”
High wind warnings and advisories are in effect until 11 a.m. Tuesday for areas including the San Bernardino Mountains, Santa Monica Mountains and San Gabriel Mountains. Apple Valley and Lucerne Valley. San Fernando Valley, Los Angeles, Orange, and San Diego County coasts.
Wind speeds are expected to be 15 to 30 mph, with gusts up to 60 mph in the windiest areas, such as the San Gorgonio Pass.
High wind warnings are in effect for most of the ocean off the coast of Southern California. Forecasters have warned that an increased risk of strong rip currents could make swimming dangerous.
