A strong storm was forecast to bring rain to San Diego County inland and coastal areas and snow to the mountains Monday with possible thunderstorms in the evening, the National Weather Service said Saturday.

Forecasters have placed Southern California in an excessive rainfall outlook risk area on Monday. Street flooding was a concern, as was an expected heavy rainfall rate on the mountain burn scars.

Snowfall of 1.5 to 2 inches starting around 7,000 feet Monday were expected to lower to around 5,500 feet Monday night, forecasters said.

Rainfall totals of 1 to 1.5 inches along the coast and in the valleys were forecast.

Lingering showers Tuesday morning were expected to end by the afternoon. Brief ridging Wednesday could bring a dry and warmer day.

On Thursday and Friday, an inside slider may bring a few showers and gusty winds to the region, but any rain amounts were expected to be light, the NWS said.

As for this weekend, Saturday was predicted to be another warm day in the valleys, mountains and deserts with a few record highs possible, the NWS said. Sunday could be a little cooler, but warm by late March standards, and above average in most areas inland from the coast.

High temperatures along the coast Saturday were predicted to be 67 to 72 degrees with overnight lows of 48 to 53. Western valley highs were expected to be 76 to 81 and 80 to 85 near the foothills with overnight lows of 48 to 53.

Highs in the mountains were expected to be 76 to 84 with overnight lows of 45 to 52, and highs in the deserts will be 96 to 101 with overnight lows of 58 to 66.

Gusty winds over the coastal waters Saturday combined with rough, choppy seas could lead to conditions hazardous to small craft. A longer period swell may develop late Monday into Tuesday, resulting in combined seas close to 10 feet in the outer waters.

A longer period west swell at county beaches was likely to develop Monday night and continue through Tuesday. This could bring elevated surf of 6- 8 feet. The surf was expected to subside Tuesday night and Wednesday.
