A Flood Watch has been issued by the National Weather Service for the Central Coast, which is in effect from 7:00pm this evening through late Tuesday night. Heavy rain at low elevations Monday night and Tuesday may cause ponding in roadway low areas and flooding along small streams. Rainfall totals for low elevations are forecast to be 1 to 4 inches. Minor flooding along a few rivers and creeks is possible Tuesday and Tuesday night. Rivers of greatest concern include the Marys in Benton County, the Luckiamute in Polk and Benton counties, and Johnson Creek in Multnomah and Clackamas County. As of Monday morning, only minor flooding is predicted.
A Flood Watch means there is a potential for flooding based on current forecasts. You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop. Landslides and debris flows are possible during this flood event. People, structures and roads located below steep slopes, in canyons and near the mouths of canyons may be at serious risk from rapidly moving landslides.
