SAN DIEGO -- Forecasters Sunday were warning that cold and windy conditions are expected to develop in parts of San Diego County as 2018 gives way to 2019 -- and snow could even be possible in the mountains on New Year's Eve.
The National Weather Service declared a winter weather advisory will go into effect at 6 a.m. Monday in the mountains as a cold trough drops into the region.
Showers are expected along the west side of the mountains, and light snow will be possible above 5,000 feet earlier in the day, forecasters said. Later, the freezing level is expected to fall rapidly, possibly bringing snow to elevations above 3,500 feet.
Icy conditions are expected on mountain roads and highways including Interstate 8, especially later in the evening.
"Be prepared for snow-covered roads and limited visibility at times, and use caution while driving," the NWS said.
The snowy weather will also be accompanied by strong southwest winds of 25 to 40 mph, forecasters said.
The winter weather advisory was set to expire at 9 p.m. Monday, followed up with a high wind watch.
Strong northeast winds as high as 55 mph -- with gusts to 75 mph in some wind-prone areas -- were expected to develop on Monday evening and last through Tuesday night, the NWS said.
The winds could cause tree damage and make driving difficult. Blowing dust will also be possible and could reduce visibility, forecasters said. The high wind watch was set to expire at 4 a.m. Wednesday.
The advisories come after a weekend of cold weather in the San Diego region -- temperatures dipped into the 30s and 40s on the coastline overnight, and a frost advisory was in effect until 8 a.m. Sunday.
