The strongest storm so far this season appears likely to impact southwest Washington and 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 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 weather system early next week is expected to bring heavy rain to the Pacific Northwest.

Sharp rises are likely on rivers draining these areas, and flooding is possible Tuesday and Wednesday. Confidence in the precise timing and location of the heaviest rain for this storm remains moderate, and slight changes to the forecast should be expected and monitored over the next several days. If conditions warrant, watches or warnings for specific areas or rivers will be issued. If you live in or near a flood-prone location, this is a good time to review your preparations and action plans should flooding develop next week.
