Rain is in the forecast for the entire week along with snow in the upper elevations. Temperatures will be moderate with highs in the upper 40s and lows in the mid 40s today and tomorrow; tomorrow night will see lows around 40 degrees. Temperatures in the Newhalem area will be 5-10 degrees colder.  A southerly flow of wind will be with us through tomorrow night, at least. Gusts will be in the mid 20s but tomorrow night, gusts could get near 30mph or a little stronger.  

Rivers and Streams

The Nooksack River level will come up over the next couple of days but current forecasts keep it just below flood stage.  More rain or rising snow levels can impact the river level so continue to listen to weather radio.  The river will come up rather rapidly, so maintain a high level alert so you’re not caught off guard.

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:


Date
Height of Tide
Time of King Tide 

January 12, 2021

10.4 Feet

0605

January 13 & 14, 2021

10.6 Feet

0645 / 0722

January 15, 2020

10.5 Feet

0758

January 16, 2021

10.2 Feet

0831

January 29-February 01, 2021

10.1 Feet

0706 / 0733 / 0800 / 0827


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.


This briefing line is not updated on weekends unless an incident occurs.
