Cold Pacific storm to bring rain, gusty winds and mountain snow Tuesday

SAN DIEGO (FOX 5/KUSI) -- A winter-like system will dampen San Diego County as the storm is expected to bring some decent rainfall as well as cooler than normal temperatures to the region.

The closed upper-level low is currently situated over the coast of the California and Oregon border and expected to slide south and east into Tuesday.

First, we will get increase west to southwest wind across the county especially for the mountain and desert communities where gusts could reach more than 55 miles per hour. Along the coast and valleys, windy conditions with gusts of up to 25 miles per hour will occur Monday afternoon and evening.

Highest rainfall totals of up to an inch or more of rain are expected for inland San Luis Obispo, Santa Barbara, Ventura counties and into the Los Angeles Basin where Flood and Flash Flood Watches are in effect near burn scar areas. Rainfall amounts drop off the further south you go in Southern California but San Diego County still looks to get anywhere from a quarter to a third inch of rain for the coast, up to half and inch of rain for the valleys and near three quarters an inch for mountain areas. North County looks to pick up the highest rainfall totals.

We are already getting some sprinkles Monday afternoon but moderate rainfall rates will push through Tuesday morning with more coverage expected early afternoon between 12 - 3 p.m. Rain could be heavy at times after 11 a.m.

Showers taper off by early Wednesday morning and as the system exits to the east, we will be left with cold air. Waking up Wednesday will feel pretty chilly with overnight lows dropping to the low and mid 50's for the the beaches and valleys.

Snow alert for the Sierra Nevada mountains where up to two feet of snow could fall from this system above 7000 ft. Mammoth Mountain is looking to pick up eight to 16 inches of snow with up to four inches for communities along Highway 395. In the San Bernadino County mountains, Big Bear will get a dusting of snow with up to half an inch of snow accumulated.

Tuesday and Wednesday afternoon temperatures will peak in the mid-60s for the coast and valleys, mid-50s for the mountains and mid-70s for the deserts.

Drier conditions with a slight warming trend leads us into the weekend.
