The National Weather Service has issued a Flood Watch, in effect from Friday morning through Sunday afternoon, for most of Northwest Oregon. This includes the Central Coast and Central Coast Range.
Two storms are expected to dump heavy rain on our area during the next several days.
The first storm will begin bringing heavy rain to the Central Coast late tonight, with the highest amounts of around 2 to 3 inches expected to be in the Central Coast Range. This storm will bring rises on rivers Friday that are already running high from rain and some snowmelt during the past several days.
The second storm is expected Saturday with additional heavy rain over much of Northwest Oregon. This system is currently expected to move through more quickly with shorter duration heavy rain. Still, expect another 2 inches in the Coast Range.
There will be little time between these two systems for the rivers to recede and flooding is likely across river basins in the Central Coast Range and possibly elsewhere. Flooding of small rivers, streams and roads is also possible during the heaviest rainfall periods.
Outlook in the long-range weather models indicates another wet period early next week along with a potential increase in the local flooding threat.
A Flood Watch means there is a potential for flooding based on current forecasts. Landslides and debris flows are possible during this flood event. Structures and roads located below steep slopes, in valleys and near the mouths of valleys may be at serious risk from rapidly moving landslides.
You should monitor the latest forecasts and be alert for possible flood warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
