FERNDALE, Wash. — The Nooksack River level forecast at Ferndale continues to warn of impacts on Ferndale area roads and parks beginning tonight, Thursday, January 23rd and continuing into the weekend.
A Flood Watch has been issued by the National Weather Service that will remain in effect through Friday afternoon.
A period of warming, rising snow levels, and heavy rain in the mountains will force sharp rises on the rivers flowing off the Cascades. 1 to 3 inches of rain have fallen in Cascade Mountains the last 24 hours and another 1 to 3 inches are expected into Friday afternoon. Locally heavier amounts are possible. Snow levels will rise to around 5,000 to 7,000 feet. Locally heavier amounts are possible. River flooding is possible as a result.National Weather Service statement issued 11:15am January 23, 2020
The river level is expected to reach the 15-foot mark, when road impacts typically can expect to begin, about 5am Friday morning. The river level is expected to continue rising through the day until cresting near the 18-foot mark about 10pm Friday night.
Following weeks of rain and recent snow accumulation, the ground around the Ferndale area is over saturated, with puddling from recent rains in many places. This means any river flooding can be expected to be exaggerated and result in impacts on roads and properties sooner than normally expected.
2 weeks ago, Slater road was closed while the river was heading to a crest level of 16.6 feet. It is likely Slater Road will be closed again given the current river level forecast.
Drivers should be alert to water and debris over roads and obey road closure and detour signs.
River level forecasts are prone to frequent changes so monitoring the forecast is advised.
The MFN Traffic page will be updated with river flooding road impacts when they occur.
