Weather forecast for Saturday is now calling for light drizzle over a three hour period, possibly three-hundredths of an inch total.
A Pacific system of moderate intensity will move through the area Friday night and Saturday, bringing rain and possibly snow in the mountains. Gusty winds in the mountains and adjacent deserts and a slight chance of thunderstorms.
The rain is predicted to be mostly moderate in intensity with preliminary rainfall forecast of between one-quarter and one-half inch near the coast Friday night and Saturday.
A strong southwest flow about one mile above sea level will result in uplifting over southwest-facing mountain slopes where an inch of rain or more could fall. Also, isolated thunderstorms will be possible and could bring a short period of heavy rain. This could result in local flooding of low-lying areas. If thunderstorms occur in recent burn ares, debris flows will be possible.
The snow level will be around 5500 feet and amounts of 3-6 inches will be possible above 5500 feet.
Winds could gust over 40 mph at times in the mountains and adjacent parts of the desert. With the passage of the cold front late Friday night or early Saturday morning, a period of wind gusts over 30 mph could impact the coast as well.
High surf with occasional sets of 8 feet or more will be possible at the beaches Saturday and Sunday due to a west swell associated with this weather system.
Another system could impact the area early next week with more rain and mountain snow possible.
