Flood Watch Issued For Healdsburg, Sonoma County

HEALDSBURG, CA — Healdsburg residents should monitor later forecasts and be alert for possible flood warnings Friday and Saturday, the National Weather Service said.

A flood watch is expected to go into effect Friday afternoon and continue through Saturday afternoon during the significant rainfall forecast for the Marin Coastal Range, Sonoma Coastal Range, North Bay interior mountains, Coastal North Bay including Point Reyes National Seashore and North Bay interior valleys.

Expected rainfall totals are 2-3 inches in the valleys and up to 5 inches in the higher elevations. Excessive runoff may result in flooding of rivers, creeks, streams and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks, and flooding may occur in poor drainage and urban areas, the weather service said. Those living in areas prone to flooding should be prepared to take action should flooding develop.

The Russian River in Hopland is forecast to reach the minor flood stage of 15 feet Friday into Saturday. If it does, there would be significant flooding of state Highway 175 at the approaches to the Russian River bridge, minor flooding of state Highway 222 near Ukiah, and in cropland along the left and right banks of the river near Hopland.

The Russian River in Healdsburg is not expected to flood during this storm. It is forecast to peak at 13.76 feet Saturday night, up from 1.40 feet Wednesday morning. The river in Healdsburg does not reach minor flood stage until the water rises to 23 feet.

Coastal Flood Advisory

A National Weather Service coastal flood advisory was also issued. It remains in effect from 6 a.m. Thursday to 1 p.m. Monday.

Minor coastal flooding is expected along San Francisco Bay and San Pablo Bay. Parking lots, parks and roads are forecast to flood. Isolated road closures are expected.

Tidal levels are increasing as a result of higher astronomical tides. Low-lying areas within the San

• 6.98 feet at 8:54 a.m. Friday
