Emergency Management

Severe storms in Thurston County can take many forms, including winter storms, thunderstorms and even tornadoes. The most destructive storms in Western Washington typically occur in the fall and winter months, causing significant property damage, power loss, and disruption of critical services. High winds, heavy rain, heavy snow, freezing rain, tornadoes, hail and lightning can occur as isolated events or delivered consecutively over the course of a single weather event.

Heavy rainfall produced in a relatively short time period can often exceed the capacity of natural and man-made stormwater drainage systems leading to flooding. Excessive rainfall can also lead to erosion and saturate steep slopes, making them more susceptible to landslides.

During winter storms fueled by cold arctic air, heavy precipitation can form into snowfall or freezing rain, causing significant impacts to transportation networks for several days and hazardous driving conditions. Excessive snow and ice loads on structures, utility lines and trees can cause them to collapse, leading to significant damage and prolonged disruption of utility services.

High winds, those above 30 mph, have the potential to cause widespread damage and those above 50 mph can lead to more serious damage. During or following a winter storm, high winds can topple trees in soils saturated by heavy rain or snow, causing damage to structures, blocking roads and damaging power lines.

Although rare in Western Washington, large thunderstorms can create conditions to form a tornado, high speed rotating winds capable of ripping apart buildings, fences, street signs, and vegetation. Thunderstorms also often bring with them lighting than can start wildfires, split trees, and disrupt power transmissions. Lighting can also strike people out in the open or under an isolated tree, causing burns, paralysis, or even death.
