Emergency Management Tips and Reminders
While we are starting to come out of winter, it's important to remember, the weather at lower elevations is not what you will experience at the 5000-6000' levels. Temperatures difference of 10-15 degrees or more can result in heavy rain in the lowlands and heavy snow in the upper elevations or crossing the passes. As we cross into April and May the chances for that continue to drop but a stray weather system can still result in hazardous driving conditions. With that in mind continue to be diligent. Things to be aware of:
Have your car checked to make sure all parts are in good working order. Tires should have good tread, all lights should be working, and windshield wipers should be changed if they do not provide a clean sweep of moisture on the windshield.
If there is snow on your vehicle, clean as much snow off your vehicle as possible. Windows should be completely clean for maximum visibility. Snow left on the hood of your vehicle can blow across your windshield and fog or cloud up inside due to the temperature change (another reason to clean all snow off your vehicle). Headlights, brake lights, direction lights, etc. should all be clean again to make other drivers see you and know your intentions.
Make sure you have a Winter Safety Kit in you car that contains: flashlight with extra batteries, cell phone and charger, extra blanket and clothes, high-energy food and water, games to keep children occupied, small shovel, sand or mat for traction if you encounter icy conditions, among other things deemed necessary.
If you are running your car to remain warm, remember to leave a window open to prevent a build-up of carbon monoxide.
Before leaving on a trip, call ahead and let someone know the time you are departing and your route of travel. Likewise, upon arrival at your destination, let contact know you have arrived.
Information concerning face coverings and other protective actions can be found on the Whatcom County Health Department Website.
