Nooksack River level forecast warns of minor flooding

WHATCOM COUNTY, Wash. — The National Weather Service Seattle office said this morning, November 10th, heavy rainfall in the Cascade Mountains is expected to result in driving up the Nooksack River level. Forecast river levels are not creating concern in the upper reaches but are high enough to create road impacts in the Ferndale area.

Periods of heavy rain with a high snow level are forecast as a warm front moves through the area on Thursday. On Friday another system in this atmospheric river will bring heavy rain in the mountains and some lowland areas could see over 2 inches of rain as well. Recent heavy lowland rain has saturated soils which increases the potential for river flooding along with urban and small stream flooding.

As a result of the rain and rising snow levels, the current Nooksack River level forecast shows it cresting late Friday below actionable levels in the upper gauge locations and early Saturday in Ferndale just below the official minor flood stage range.

Road impacts expected after the river reaches the 15-foot mark in Ferndale include the following.
