Whatcom County has designated the week of October 12 through 16 as Flood Preparedness Week, giving residents a structured opportunity to assess their readiness before the fall and winter flood season arrives in full force. The county announced the observance this week, aligning with the start of the rainy season that historically brings the most significant flood risk to communities throughout the region.
Whatcom County sits at the confluence of multiple flood-prone river systems, including the Nooksack River, which drains the slopes of Mount Baker and the North Cascades. The county has experienced repeated damaging floods over the decades, with the most severe events causing road closures, property damage, and evacuations in communities from Everson and Sumas to Lynden and Ferndale.
Why Flood Risk Is High in Whatcom County
The Nooksack River watershed covers a vast area of the county, and the river's three forks converge in the flatlands near Ferndale before emptying into Bellingham Bay. During heavy rain events, especially when combined with snowmelt from the mountains, the Nooksack can rise quickly and spill into agricultural fields, residential areas, and major roads. The 2021 atmospheric river events caused catastrophic flooding that cut off entire communities in Whatcom and neighboring Skagit County for days.
The county's flood management program has been a recurring priority in recent budget discussions. The current recommended budget for 2027 and 2028 includes $30 million allocated to a county flood fund, reflecting the ongoing investment required to protect communities and infrastructure from a risk that shows no sign of diminishing as climate patterns shift.
Flood Preparedness Week is designed to move residents from awareness to action before the worst conditions arrive. Emergency managers recommend that preparation happen now, when weather is still dry enough to assess property conditions, clear drains, and gather supplies without the urgency of an approaching storm.
Steps Residents Can Take Before October 12
Whatcom County Emergency Management encourages residents in flood-prone areas to take several concrete steps in the weeks ahead. These include knowing your flood zone designation, which can be looked up through the Whatcom County website using your property address. Properties in Special Flood Hazard Areas face the highest risk and are subject to federal regulations around flood insurance and development.
Residents should also confirm that their household has a go-bag ready with essential documents, medications, phone chargers, water, and a few days' worth of food. Flood evacuations can happen with little warning, particularly when river levels rise overnight during heavy rain. Knowing your evacuation route and having a destination in mind for family members and pets is equally important.
For homeowners, checking that gutters, downspouts, and drainage ditches are clear of debris before the rainy season begins is one of the most effective and lowest-cost flood preparedness steps available. Blocked drainage can turn a manageable rain event into localized flooding that damages foundations, garages, and crawl spaces.
What to Expect During Flood Preparedness Week
The county typically uses Flood Preparedness Week to share educational resources, host informational events, and promote awareness through social media and partner agencies. Residents can expect updates from Whatcom County Emergency Management throughout the week with specific preparedness tips, local flood history, and information about community resources available to households that experience flood damage.
The National Flood Insurance Program offers coverage for flood damage that standard homeowner's insurance does not cover. Residents who have not reviewed their flood insurance status recently are encouraged to do so before October, as policies typically have a 30-day waiting period before coverage takes effect. More information is available through FloodSmart.gov, the federal government's flood insurance resource portal.
Whatcom County Emergency Management updates the public on conditions through its daily briefings and social media channels. As flood season approaches, those channels become an increasingly valuable resource for residents who want real-time information about river levels, road conditions, and evacuation orders in their area.
