WHATCOM COUNTY, Wash. — National Weather Service forecasters in the Seattle office are concerned about the potential for flooding as the second in a series of “moisture surges” is expected to arrive late Sunday.
Additional moderate to heavy rainfall early next week is expected as a series of atmospheric rivers may take aim at the Pacific Northwest. Each of these potentially intense systems are lined up to impact the region every 24 hours or so. This could lead to additional river flooding, especially with snow levels likely remaining elevated with these warm and moist weather systems leading to progressively higher flows through at least the first part of next week. Confidence remains somewhat low in pinpointing any particular basins for early next week due to the complex evolution of the pattern and the uncertainty of the impact of snowmelt, combined with heavy rain and warming.National Weather Service Seattle office (December 21, 2022)
Current river level forecasts for key locations along the Nooksack River in Whatcom County reflect the expected increases but fall short of reaching “Action Levels.”
River level forecasts can change frequently so drivers and property owners are advised to monitor the Nooksack River level forecast.
