Storm records for Okanogan County

Only one Washington county logged more storm reports than Okanogan. NOAA recorded 581 here from 2016 through 2026, second of 39, across 5,266 square miles of valley, highland and Cascade east slope. Heavy snow accounts for 419 of them and wildfire for 77; winter weather (21), thunderstorm wind (18), winter storms (14), high wind (13), strong wind (10), ice storms (5) and hail (4) fill out the record.

January is the peak by a wide margin with 198 reports, then December with 102 and February with 76; 72% fall between November and February. Summer is not quiet either: August and September together logged 61 reports.

The pace has slowed. Reports fell from 187 in 2020 through 2022 to 66 in 2023 through 2025, a 65% drop, after highs of 106 in 2018 and 111 in 2020. NOAA tied 2 deaths and 5 injuries to the county’s reports over the period.

Largest recent episode: 2017-01-17: 20 reports (Heavy Snow 12, Winter Storm 5, Ice Storm 3).

On January 17 and 18, 2017, an atmospheric river carried Pacific moisture into eastern Washington and turned it into widespread snow and freezing rain. Mountains and valleys north and west of the Columbia Basin got heavy snow, while in the Basin itself warm air rode over a shallow layer of arctic cold, so rain froze on contact and glazed roads. NOAA filed 20 reports from the episode in the county’s zones: 12 heavy snow, 5 winter storm and 3 ice storm. The costliest entry belongs to the 2018 fire season, when dry thunderstorms in late July started fires that grew large in mostly unpopulated forest without destroying homes; NOAA attached $81.7 million in damage under an August 1, 2018 date.

Hazard ratings

Strong wind: Relatively LowIce storm: Very LowWinter weather: Relatively ModerateWildfire: Relatively High

FEMA’s National Risk Index (December 2025) rates Okanogan County Relatively High for wildfire (99.3) and Relatively Moderate for winter weather (71.3), with strong wind Relatively Low and ice storm Very Low; the overall rating is Relatively Moderate. The Forest Service puts wildfire risk to homes here above 90% of Washington counties.

So tree work has a fire job and a snow job. Fire work means removing dead conifers near buildings, limbing up and thinning under the defensible space approach. Snow work means pruning long limbs over roofs and drives before January.

Wildfire risk to homes: higher than 90% of Washington counties (USDA Forest Service, Wildfire Risk to Communities).

Burning the debris

Okanogan County has no local clean air agency, so the Washington Department of Ecology’s statewide outdoor-burning rules govern. WAC 173-425-040 prohibits residential and land-clearing burning inside urban growth areas and cities over 10,000; no city here reaches that size, but urban growth areas around towns such as Omak can still apply. WAC 173-425-050 adds the prohibited-materials list, the attendance rule and the 50-foot setback. With 77 wildfire reports on file, also check for seasonal burn bans before you light anything.

Power lines and utilities

No utility is mapped for Okanogan County on this site yet, so its outage line and clearance rules are not shown. Find your utility on your bill and check the utilities index. Trees growing toward lines matter twice here, as a winter outage risk in a county with 419 heavy-snow reports and as a summer ignition source; ask the utility about clearance before fire season and leave anything touching a line to its crews.

Cities and towns in Okanogan County

Okanogan County’s 45,230 people (Census 2025 estimate, up 7.44% since 2020) are spread over 5,266 square miles, and its six listed cities are all small: Omak (4,860), Okanogan (2,379), Brewster (1,983), Oroville (1,795), Coulee Dam (1,211) and Tonasket (1,103). None has been researched for tree rules on this site yet.

Together those cities hold about 13,300 people, so most of the county lives outside city limits, where county rules apply. Ask the city or county planning office before a large removal.

Labor index

BLS puts Washington’s mean wage for tree trimmers and pruners at $32.20 an hour (May 2025); no Okanogan estimate is published, so the statewide number is used. That is pay, not the price of a job. Census County Business Patterns counted 24 landscaping-services establishments in the county in 2023, few for 5,266 square miles, so expect travel time in bids and book well ahead of fire season.

Washington statewide: $32.20 per hour mean wage for tree trimmers and pruners (BLS, May 2025); no metro estimate is published, so the statewide figure is shown. This is a labor index, not a price; the modeled crew-hour cost used on this site is $210 (method).

Climate and growing conditions

Okanogan County spans four hardiness zones on the 2023 USDA map, 6a through 7b, with 6b the most common. Check your ZIP before buying: stock that suits a low valley site may not survive the highlands. Replant with spacing and snow in mind; ponderosa pine is the native large tree on the dry slopes, and keeping new plantings clear of the house fits the defensible-space approach.

What to do next

Sort the tree by threat. Dead or crowded conifers near buildings are a fire problem, so move them up the list before summer. Heavy limbs over a roof are a snow problem; prune them before the January peak. A risk assessment covers both, and for work inside town limits, call the city first.

Then check the contractor through the Washington license lookup and compare its quote with the modeled range on the cost page.
