SAN DIEGO (KGTV) -- San Diegans are feeling the effects of a winter storm moving through the county Thanksgiving weekend.

The storm is expected to dump heavy rain along the coast and snow in the mountains.

Heavy rain expected throughout San Diego County

A flash flood watch was issued from late Tuesday night through Thursday evening.

According to the National Weather Service, rainfall totals of two to three inches are possible, especially on coastal mountain slopes.

Some areas could also see rainfall rates of half an inch per hour.

"The threat for flash flooding is greatest in the mountains below 5,500 feet through Wednesday, below 4,500 to 5,000 feet for Wednesday night through Thursday, and on the lowest elevations of the mountains for Thursday evening," the agency said.

Snow expected to impact travel

A winter storm warning is in effect for the San Diego County mountains from 4 a.m. Wednesday through 10 p.m. Friday.

The National Weather Service says snowfall accumulations of 3 to 6 inches are expected between 4,000 and 4,500 feet, 6 to 18 inches from 4,500 to 5,500 feet, and from 1 to 3 feet above 5,500 feet.

Snowfall for lower elevations below 4,000 feet of 1 to 3 inches is also expected, mostly for late Thursday through Friday.

Strong southwest winds of 50 to 70 miles per hour are also expected along ridges and desert slopes.

The snow is also expected to impact travel over the course of Thanksgiving weekend. Up-to-the-minute traffic conditions are available online here. Check out the image below to see which roads are expected to be impacted by the snow:

Road closures

The Quarry Drive Dip in Spring Valley closed Wednesday night between SR8125 and Lakeview Ave due to flooding.

Beach hazards during storm

A beach hazards statement is in effect through Friday morning as waves and surf are forecast to reach between three to five feet. Higher sets from six to seven feet are also forecast through Friday.

Minor coastal flooding is expected during morning high tides with the highest surf arriving Thursday and Friday.

The Department of Environmental Health issued a General Advisory for the coastal waters of San Diego County due to bacteria in runoff. Surfers and swimmers should wait 72 hours after the end of a storm to enter the water, health officials said.
