King County officials urge preparedness as ‘La Niña’ forecast could amplify river flooding


Images of people as they are rescued from homes and cars inundated by rising floodwaters in Texas, Puerto Rico and elsewhere underscore why preparation and awareness of flood hazards are so important. And with climate scientists calling for a “La Niña” winter weather pattern to soak the Pacific Northwest, King County and the King County Flood Control District proclaimed October as Flood Awareness Month.


Recent severe flood damage in Texas, Florida and Puerto RicoFlood Control Zone District Logo is a grave reminder to prepare for possible flood hazards – particularly as climate scientists predict a “La Niña” weather pattern this winter that could mean more flooding from rain-laden storms across King County.

King County Executive Dow Constantine and the King County Flood Control District Chair Reagan Dunn today declared October as Flood Awareness Month, and urged everyone to prepare now for potential flood emergencies in the coming months.

“More Americans die each year from flooding than any other natural disaster,” said Executive Constantine. “It’s important to prepare for flooding now through basic steps such as assembling emergency preparedness kits and signing up for King County Flood Alerts.”

“I would encourage anyone living in a flood plain to start thinking ahead about how you can prepare for this upcoming flood season,” said Reagan Dunn, Council Vice Chair and Chair of the King County Flood Control District. “With all the resources King County provides it’s easier than ever to be well informed about how to best protect your home, business, or property from flood damage.”
“We are seeing devastating flooding across the country with alarming frequency,” said King County Councilmember Dave Upthegrove, Vice Chair of the King County Flood Control District. “It is important that we raise awareness with King County residents so they can better protect their families, businesses and property from floods.”

Climate scientists note that last year’s weak “La Niña” winter weather pattern resulted in severe storms across much of the Pacific Northwest. Seattle received about 1 foot more rainfall than average from October 2016 through March of this year.
River flooding has led to 12 presidentially declared disasters in King County since 1990.
To prepare for a flood emergency, families can assemble a basic emergency preparedness kit for the home, with items such as a flashlight with spare batteries, a portable radio, non-perishable food, drinking water, extra clothes, cell phone chargers and books or games for kids.

King County provides information to allow residents the maximum amount of time to prepare for potential flooding on any of the county’s six major river systems, as well as the South Fork Skykomish River in the northeastern corner of the county.

Additional preparations for flood season include:

•    Buying flood insurance now. It takes 30 days for a policy to take effect, and a standard insurance policy will not cover flood damage. Contact your insurance agent or visit
•    Monitoring local media for information when severe weather is predicted. Listen for alerts about evacuation routes, and monitor local road conditions and obey closure signs.
•    Minimizing flood damage by storing valuables and electronics higher, and by moving vehicles and equipment to high ground before flood waters rise.
•    Disposing of hazardous chemicals, such as lawn and gardening herbicides, at one of the county’s household hazardous waste sites to help reduce harmful contaminates in flood waters. Learn more at

When flooding is imminent, King County employees gather, analyze and distribute flood warning information so that residents, businesses, property owners and emergency responders can make important public safety and economic decisions.

Once rivers rise to designated thresholds, King County's Flood Warning Center  opens to monitor river gages, weather data, dam operations and road closures, 24 hours a day until the flood threat has passed.

County employees head into the field at designated flood levels to address safety concerns, such as flooded roadways, and to check on flood control facilities.

When the Flood Warning Center is open, citizens can speak directly to King County employees 24 hours a day by calling 206-296-8200 or 1-800-945-9263. Interpreter services are available.

Questions or assistance with flooding on smaller streams or urban drainage problems can be called in to 206-477-4811 during business hours or 206-477-8100 after hours or on weekends.

Efforts to protect people and property have earned King County a high from the Federal Emergency Management Agency's Community Rating System (CRS). King County’s high CRS rating is saving policyholders in unincorporated King County more than $1 million in flood insurance premiums – an average of $425 per policy.
