Kittitas County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Kittitas County: 0.
2. Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

Every large fire

1. Large fires mapped by the Monitoring Trends in Burn Severity program since 1984: 1,000 acres or more in the West, 500 or more in the East. Prescribed burns are excluded. Acres here are the part of each perimeter inside this place.

Monitoring Trends in Burn Severity (USGS and U.S. Forest Service), 1984 to 2026.

Smoke overhead

1. A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

River crests

River gauges

1. Crests are the highest and the recent crests the National Weather Service lists for each river gauge in the county that has a flood stage, not every flood. Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

1. The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

Every earthquake of magnitude 4 or more within 50 miles

1. Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the county boundary (or inside the county).
2. Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

Volcanoes within 100 miles

1. U.S. volcanoes within 100 miles, from the USGS Volcano Hazards Program. The threat category is the USGS 2018 National Volcanic Threat Assessment, which ranks volcanoes by how hazardous their past eruptions were and how many people and how much infrastructure lie near them. It is not a forecast of eruption.

Mapped landslides

Mapped by WA WGS (2,501), West Coast Slow Moving (Yuankun and others, 2021) (18), NASA (4), USGS Conterminous (2).

1. Landslides mapped in the USGS compilation of landslide inventories across the United States (version 3.0, 2025), rated probable or better. The compilation joins inventories made by federal and state agencies for different purposes and areas, so the number mapped in a county reflects how closely it has been surveyed as much as how often its slopes fail. An area with few records may simply not have been mapped. Deaths are as recorded in the inventories; a slide listed in two inventories is counted once.

More event types since 1996

Costliest events since 1996

1. Jan 7, 2009Flood$10.0 million
   National Weather Service narrative

   Heavy rain on deep snow caused moderate flooding with damage in Elk Meadows subdivision, Cle Elum, Roslyn, and the west portion of Ellensburg. Roads were flooded and buckled in many areas.

2. May 15, 2011Flood$4.0 million
   National Weather Service narrative

   Flood waters damaged or closed 22 roads along Manastash, Taneum, Cooke, Coleman, Wilson, and Caribou Creeks. Bridges and irrigation systems were also impacted.

3. Jan 15, 2011Flood$2.1 million
   National Weather Service narrative

   In addition to the high water on the Yakima River, numerous small streams and creeks in the west part of the county flooded with roads covered with water in housing developments along Interstate 90 west of Cle Elum and in the northern and western sections of Ellensburg. Forty homes, 64 roads and 3 commercial properties were impacted. Most of the home impacted were surrounded by water with residents cut off from the property by water covered roads. Damage to roads and public works in Kittitas County is estimated at 1.5 million dollars with residential and business damage near 650,000 dollars.

4. May 14, 2011Lightning$300,000
   National Weather Service narrative

   Lightning started a roof fire which damaged a few other rooms of a residence.

5. May 4, 2005Flash Flood$90,000
   National Weather Service narrative

   Very heavy rain fell near Vantage along interstate 90. This resulted in water, mud, rocks, and debris running down the sides of Ryegrass Coulee and onto the shoulders of eastbound lanes on interstate 90 at several places about three miles west of Vantage. Severe erosion damaged the freeway embankment, leaving vertical drop offs of severeal feet. Three to four inches of water was also running across the road on the Vantage Highway. The estimated cost of fixing the damaged three miles stretch of interstate 90 was $90,000.

6. Sep 19, 2010Lightning$60,000
   National Weather Service narrative

   Lightning struck an 80 foot fir tree and started a house fire. The lightning split the tree and the energy was transferred into the cast iron sewer pipe and into the home catching the house on fire. A large piece of the split tree hit a car that was parked across the street.

7. May 19, 2001High Wind, Kittitas Valley$20,000
   National Weather Service narrative

   High pressure building west of the Washington Cascades, combined with a cold front moving through the Columbia basin, brought high winds to the Kittitas Valley.

At 12:15 pm, a large tent at the Ellensburg National Art Show and Auction was damaged, prompting a hasty evacuation. Shortly before 1 pm, wind gusts estimated between 50 and 60 mph toppled a tree onto some power lines along Kittitas Road just east of Ellensburg.

8. Feb 12, 2011Strong Wind, Kittitas Valley$10,000
