Statement as of 10:38 AM PDT on September 14, 2013
... A vigorous low pressure system will bring showers and scattered
thunderstorms to western Washington Sunday into Sunday night...
A big change to the western Washington weather pattern will unfold
Sunday. Low pressure off the Oregon coast Sunday morning will lift
northward bringing a change to unsettled weather across western
Washington. A strong marine push is expected ahead of this system
around late morning or midday Sunday producing a burst of breezy
southwesterly winds. Securing loose items like garbage cans and
patio furniture is recommended. Those on the water in watercraft
should be especially cautious of the rapid onset of winds.
The air mass aloft will become unstable during the day Sunday.
Monsoon moisture over the northern Great Basin will also be pulled
into the Pacific northwest. This combination will result in
widespread showers and scattered thunderstorms. General rainfall
amounts from noon Sunday through midnight Sunday night will range
from a quarter to a half inch across the area. However... some
thunderstorms could produce locally heavy rain amounts over an inch
in a short period of time. This could result in localized ponding of
water on roadways and may overwhelm drainage systems.

Service. The latest information can be found on
