NWS Alerts: A Special Weather Statement has been issued by the National Weather Service for the strongest storm so far this season, which appears likely to impact Northwest Oregon late Monday into Tuesday, bringing heavy rain and gusty winds to the region. Strong south winds are expected to develop along the coast Monday, then spread inland Monday night and Tuesday. Winds strong enough to down trees and power lines are expected along the coast and in the higher elevations of the Coast Range. There is also the potential that strong winds will affect the inland valleys, particularly the Willamette Valley. Details remain uncertain, but at this point it appears central and southern portions of the Willamette Valley have the better chance to experience winds strong enough to cause damage to trees and power lines. The combination of heavy rain and strong winds may make travel difficult across the region Monday night and early Tuesday.

A High Wind Watch is in effect for the Central Coast from Monday afternoon through Tuesday morning. In coastal communities, south wind 30 to 40 mph with gusts up to 60 mph. On beaches and headlands, south wind 35 to 45 mph with gusts up to 70 mph. Most likely, the high winds may increase Monday afternoon and continue until early Tuesday morning. Damaging winds may blow down trees and power lines. Power outages are possible. Travel may be difficult, especially for high profile vehicles.

The latest Hydrologic Outlook projects flooding possible Tuesday and Wednesday in Northwest Oregon. The potential for 2-5 inches of rain exists with sharp rises on area rivers. If you live in or near a flood-prone location, this is a good time to review your preparations and action plans.
