The National Weather Service in Seattle has issued a flood watch for all rivers in Grays Harbor County from Wednesday afternoon through Thursday night, according to Grays Harbor emergency management officials. The county is expected to receive 2-4 inches of rain, which could cause minor flooding on area rivers.
There may be breaks in the fast moving storms that would assist in runoff and prevent localized flooding and as of Tuesday afternoon, no rivers in Grays Harbor County were expected to reach flood stage, said Chuck Wallace, deputy manager of the county’s emergency management division.
A storm arriving Thursday is expected to bring wind gusts of 40 mph. The National Weather Service says that while 40 mph is not out of the ordinary for this time of year, the concern is ground saturation along with high wind gusts. Trees could topple causing power outages and road closures. Driving will be extremely hazardous during the high winds and heavy rain which could make visibility very limited. Localized roadway flooding could also cause dangerous driving conditions.
Because to the extreme amount of rainfall this past week, the National Weather Service in Seattle has issued a Special Weather Statement on the increased risk of landslides. Rainfall of 1 to 3 inches over the past couple days has increased soil moisture to high levels across Western Washington. Additional heavy rainfall of 2 to 4 Inches is expected Wednesday into Thursday. This amount of rain will put extra pressure on soil instability leading to an increased risk of landslides.
Landslides have been reported in various locations in Western Washington including Grays Harbor County, where a slide near Vesta blocked the North River Road for a time on Monday.
