Statement as of 3:45 am PST on November 26, 2011 – Areal Flood Watch
… Flood Watch remains in effect through Monday afternoon…
The Flood Watch continues for
* portions of western Washington… including the following counties… Whatcom… Mason… Snohomish.
* Through Monday afternoon
* heavy rain is forecast to fall over the Olympics and north Cascades beginning tonight and continuing into Sunday. The river model run by the NWS river forecast center brings the Skokomish River in Mason County to flood stage Sunday afternoon and the Nooksack river at north Cedarville in Whatcom County to flood stage Sunday evening. The Stillaguamish river in Snohomish County also gets close to flood stage… according to the model.
* The amount of rainfall during this period is uncertain. The two main forecast models still show differences in timing and precipitation amount… and have trended slightly lower in precipitation amount. The river model was fed by the wetter of the two models. If rainfall turns out to be significantly less than what the wetter weather model predicts… any flooding is unlikely.
Precautionary/preparedness actions…
A Flood Watch means conditions are favorable for flooding but flooding is not imminent or occurring. Monitor the latest forecasts from the National Weather Service and be ready to act quickly if flooding is observed or a warning is issued.
