Pair of rainstorms take aim at Bay Area

Two more wet weather systems are expected over the next five days in the San Francisco Bay Area before the air gets cooler and drier late next week, National Weather Service officials said Friday.

The first system will start on Sunday by dropping rain in the North Bay and impact the rest of the region on Sunday night and Monday. A second weaker system will move into the area Tuesday night and Wednesday.

The storms could cause the flooding of creeks, streams and rivers such as the Russian River at Guerneville and the Napa River in Napa, National Weather Service meteorologist Brian Garcia said.

The current forecast shows the Russian River topping out at 32.5 feet during the storms. The Napa River is expected to reach monitor stage, according to Garcia.

The Salinas River is expected to stay below flood stage.

Both storms will bring higher winds and moderate to heavy rain along with the possibility of mudslides, rockslides, downed trees, hydroplaning and flight delays and cancellations.

Coastal erosion is possible in Pacifica where at least one apartment building was demolished because erosion threatened to cause the building to fall into the ocean.

Flash flood warnings are possible from late Sunday into Tuesday, weather officials said. A flash flood warning means flash flooding is occurring or imminent.
