The U.S. and Canada have extended an order closing their shared border to nonessential traffic until at least January 21, 2021. This includes both vehicular and boating between the countries.

Weather Around Whatcom County

Whatcom County Inland Weather

The weather warnings (wind and snow) are the weather story for today.  High temperatures will be mostly in the mid-40s or even a little warmer with lows tonight near 40.  Tomorrow, highs will be about the same as today but lows will drop down to the mid-30s as the clouds begin to thin.  Thursday is still forecast to be partly to mostly sunny with highs in the low 40s and lows in the mid 30s.  Higher elevations will be 5-10 degrees colder.

Rivers and Streams

The Nooksack River along with small streams will again see a spike of sorts that will begin later today and last into tomorrow.  There is no flooding forecast but you can expect to see the river levels rise and if you have any activities planned on or near the river, be cautious of rapidly rising water.  Likewise, small streams should not be taken for granted as areas where pooling occurred could suddenly release larger amounts of water catching one off-guard.
   

Whatcom County Coastal Weather

For the Strait and Inland Coastal Waters off Whatcom County wind is the concern today and tonight.  Strong southeast winds have led to both a “Small Craft Advisory” “Gale Warning to be issued.  Winds will start to die down after midnight but expect another “Small Craft Advisory” to be issued after the Gale Warning expires at 4:00am tomorrow morning. Changes can occur rapidly so monitor marine weather.

Emergency Management Tips and Reminders

COVID-19

Everyone in Washington State is directed to wear a face covering while at any indoor public space and any outdoor public space where you may be within 6 feet of someone who does not live with you. You can find more info about face coverings and other protective actions here and here.

King Tides

A King Tide is a non-scientific term people often use to describe exceptionally high tides. Tides are long-period waves that roll around the planet as the ocean is "pulled" back and forth by the gravitational pull of the moon and the sun as these bodies interact with the Earth in their monthly and yearly orbits. Higher than normal tides typically occur during a new or full moon and when the Moon is at its perigee, or during specific seasons around the country.

In Whatcom County we pay particular attention to King Tides that occur in the late fall / early winter as many times these coincide with, and can be aggravated by, our wind storms.  This has resulted in significant impacts in our coastal communities, such as occurred in Birch Bay and Blaine in December of 2018 when over 5 million dollars in damage was caused by a King Tide and wind storm.  We define a King Tide as a tide of at least 10.1 at Cherry Point (Whatcom Counties official tide station).  Over the next couple months, we will have King Tides on the following days:

For those who are tide watchers, these are pretty impressive tides but as happened in the 2018 storm, the tides were pushed nearly two feet higher from the storm pressure (called storm surge) and then the west wind added another 3-4 feet of waves.
