Storm records for Walla Walla County

The trend is down in Walla Walla County. NOAA’s Storm Events database holds 121 reports for the county from 2016 through 2026, 18th of Washington’s 39 counties, but the most recent three full years produced 22 against 41 in the three before. The peak year was 2021 with 18.

Snow drives the record. Heavy snow accounts for 63 reports, high wind 29 and wildfire 11, with ice storms and thunderstorm wind at 5 each. February is the heaviest month with 35, followed by December at 23 and January at 17, and 68 percent of all reports fall between November and February. One injury appears in the file.

Fewer storms does not mean fewer brittle limbs. Wet snow on the Blue Mountain foothills and in town still loads evergreens and the big shade trees along older streets, so pruning before December remains the cheaper path.

Hazard ratings

Strong wind: Relatively LowIce storm: Relatively HighWinter weather: Relatively ModerateWildfire: Relatively Low

FEMA’s National Risk Index (December 2025 release) rates Walla Walla County Relatively High for ice storms, Relatively Moderate for winter weather, and Relatively Low for strong wind and wildfire, with an overall rating of Relatively Low. The Forest Service puts wildfire risk to homes here above 60 percent of Washington counties.

Ice is the rating to take seriously. A freezing-rain glaze coats every twig at once, and wide deciduous crowns over roofs and driveways fail first. Wind still carries the costliest entry in the NOAA file: on April 27, 2018, a low-pressure system drove strong wind across the Columbia Basin, with about $1 million in damage recorded for the county.

Wildfire risk to homes: higher than 60% of Washington counties (USDA Forest Service, Wildfire Risk to Communities).

Burning the debris

The Washington Department of Ecology’s statewide outdoor-burning rules apply in Walla Walla County; there is no local clean-air agency rule layered on top. Residential and land-clearing burning is barred in urban growth areas and in cities over 10,000 people, which takes in Walla Walla. Where burning is allowed, prohibited materials stay off the pile, someone must attend it, and it needs a 50-foot setback.

Labor index

BLS puts the mean wage for tree trimmers and pruners in Washington at $32.20 an hour; no figure is published for the Walla Walla area alone, so the statewide number is used. Read it as a labor index, not a price: the modeled crew-hour rate below adds equipment, insurance and disposal.

The Census counted 33 landscaping-services establishments in the county in 2023, so expect a short list of crews and plan around winter demand.

What to do next

Have a tree risk assessment done on any large tree over the house before winter, when snow and ice put it to the test. Confirm the city rule in Walla Walla, College Place or Waitsburg before a removal, and check whether the debris can be burned at all under Ecology’s rules.

Before you sign, look the company up through the Washington tree service license lookup, and compare the bid with the modeled cost ranges.
