Unsettled weather conditions will persist through the middle of the upcoming work week as Pacific storm systems impact the San Francisco/Monterey Bay region, the National Weather Service reports.

The first system, moving through as of Saturday morning, will bring periods of light rain to much of the area through Sunday. Moderate to heavy rainfall rates can be expected at times in the most intense rain bands. Precipitation will diminish Sunday night through Monday ahead of a stronger system developing offshore. This system will likely bring widespread rainfall to the entire region Tuesday and Wednesday as it slowly approaches the coast. Strong and locally gusty winds will be a possibility along the coast and in higher elevations as the system nears the region. In addition, minor flooding of low-lying and poorly drained areas may occur as well as debris flow across recent burn scars.

When all said and done, the weather service said, rainfall amounts of 1 to 3 inches of rainfall (3 to 5 inches in the coastal ranges) will be possible over most urban areas through next week.
