Inland Whatcom County Weather
A slight chance of a shower will remain around the county this morning, especially towards the foothills. This will give way to more sun as the day goes on. High temperatures today will be in the mid to upper 60s. Winds will be light. Tonight will be partly to mostly clear with lows dipping into the mid-40s. Tomorrow will start out mostly sunny but then begin to cloud up as the day goes on. The chance of showers for tomorrow night looks pretty good and that will continue into Wednesday. Highs tomorrow will b e a little warmer with mid 70s and perhaps even an upper 70 degree reading in places. As the next front moves in tomorrow night, look for the wind to pick up a little, mostly in Point Roberts where gusts to 21 mph from the west could occur. Wednesday night will be mostly cloudy and then we will once again enter a rain patter that will continue into Friday with some heavy rain forecast in the Maple Falls and Newhalem areas.
Rivers and Streams
We can see an interesting rain event setting up as we move into Thursday and Friday. Heavy rain is going to push the rivers up in a fairly large was for this time of year. There will not be any flooding, but the predictions show the river almost doubling from its lower levels. Smaller streams are likely to see increased flows and possibly exceeding their banks a little bit. Bottom line is this, if you are going to be on or near the river beginning Thursday through Sunday, exercise extreme caution as the rise will occur rather quickly. In addition, the water will be extremely cold so hypothermia should be at the forefront of your mind as well. Remember, you can always go to the Public Works website and check the river levels - https://www.whatcomcounty.us/666/Forecasts-Current-River-Conditions.

Emergency Management Tips and Reminders
With the type of spring we've been having, vegetation has had exceptional growing conditions. The problem will begin to develop when the wet weather begins to subside and temperatures continue to warm up. As the vegetation dries out, the risk of fire danger begins to increase. Dry vegetation next to one's home or other building can ignite easily and transfer the fire to the structure. Likewise, tall grass and bushed that reach into the trees can act as ladder fuels and enable fire to climb into the trees which can then be moved by embers farther and faster. Now is the time to begin removing excess vegetation before it reaches that higher risk category.
Now also is the time when a lot of us are planting flowers and shrubs around our homes and yards. When selecting flowers or shrubs, it is highly recommended that you plant native flowers and shrubs as these types of vegetation naturally grow here. Plants that are not native may dry out faster, have oils that could produce hotter flames, and ignite faster than native plants. Firewise is a national program that provides some guidance on how to prepare your home for wildfire.
Information concerning face coverings and other protective actions can be found on the Whatcom County Health Department Website.
