HEAVY RAIN AND GUSTY WINDS EXPECTED ACROSS SOUTHWEST
WASHINGTON AND NORTHWEST OREGON LATE MONDAY INTO TUESDAY…

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. Stay
tuned to weather.gov/portland, NOAA weather radio, or your
favorite source of weather information for the latest updates on
this evolving weather situation.
