For Birch Bay area residents affected by coastal flooding, please see the announcement below from Whatcom County Public Works River and Flood.  There is a possibility of tides  in the 11-12 foot range Thursday and Friday.

The forecast shows potential for some minor to moderate coastal flooding for the next few days as a result of high winds along with tides potentially running 2-3 feet above predicted levels due to unusually low atmospheric pressure.  Below is a list of the predicted and projected (guestimates).  Cherry Point water levels and impacted areas near the time of high tides based on the National Weather Service (NWS) weather/wind/wave etc. forecast for Georgia Strait west of Whatcom County.
