...Wet and windy week ahead for southwest Washington and northwest Oregon...

A strong and wet Pacific storm system will bring periods of heavy rain to southwest Washington and northwest Oregon tonight through Thursday morning. Strong winds are also expected along the coastal headlands and higher terrain of the Coast Range tonight into Wednesday morning.

South winds are increasing along the coast this afternoon as the front approaches the Pacific northwest coastal waters. Winds will be especially strong along the beaches and headlands...where gusts of 60 to 70 mph are expected at times tonight through early Wednesday. Coastal communities may see gusts upwards of 50 mph as the front slowly sags down the coast later tonight into Wednesday morning.

South winds will also increase later tonight into Wednesday for the inland valleys and main Metro areas...where gusts of 25 to 35 mph are possible. Many trees still have a fair amount of leaves on them...which could cause more limbs to break than is often the case with such winds. As a result...some minor power outages are possible as the gusty winds develop.

The frontal system has tapped into sub-tropical moisture which will enhance rainfall near the front as it slowly moves through the area tonight through early Thursday. Rain will be heavy at times along the coast and in the higher terrain...and possibly in the inland valleys as well.

Rainfall totals of 1 to 2 inches are expected in the inland valleys by Thursday afternoon. Coastal locations are expected to receive 2 to 4 inches of rain...and 3 to 6 inches of rain are forecast for most of the Coast Range and Cascades.

Minor urban flooding is possible due to Autumn Leaves clogging storm drains...especially Wednesday into Wednesday night when the heaviest rain is expected. Additionally...there is a possibility of minor flooding on a couple of fast responding small streams and rivers due to the heavy rain. Burn scar areas from recent wildfires in the Cascades may also be subject to debris flows or mudslides. All of this will be monitored closely over the coming days.

After a lull on Thursday...another strong system may affect part of the area Friday into this weekend. Details on this system are still quite uncertain... but it appears southwest Washington and northwest Oregon is in for a fairly extended period of wet and unsettled Fall weather.
