Latah County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Latah 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.

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).

Mapped landslides

Mapped by ID GS (49), NASA (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.

   The fire start 8 miles from east of Kellogg. It burned an estimated 213 acres of timber, litter, and 3 out buildings. Around 200 people impacted by evacuations around Elizabeth Park and Elk Creek. It was contained on June 23. Wind gusts were into the low 20 mph range. Damage is estimated.

8. Aug 1, 2018Wildfire, Central Panhandle Mountains$1.3 million
   National Weather Service narrative

   The Surprise Creek Wildfire in a remote portion of Shoshone County is believed to have been caused by lightning on July 27th. It grew and eventually burned 3300 acres of timber in a wilderness area. No structures were threatened or lost. The cost of firefighting resources to contain the blaze was calculated at 1.3 million dollars.

9. May 6, 2005Flash Flood$1.0 million
   National Weather Service narrative

   On the evening of the 6th of May, a slow moving line of thunderstorms moved across central Idaho. These thunderstorms dumped one to three inches of rain in an hour across portions of the Idaho Palouse. A flash flood moved into Hubble Gulch and washed out Hubble Gulch Road and a few structures in Nez Perce County. Numerous roads were also washed out in Latah County with the same storms. There was an estimated 2 million dollars damage to roads and structures total for both counties because of the flash flooding.

10. Feb 24, 1999Flash Flood$1.0 million
    National Weather Service narrative

    A combination of rapid snowmelt and heavy rain caused small streams to flood and roadways to pool with water especially across southern Latah County.

1. Storm Events records before 1996 cover only tornadoes, thunderstorm wind and hail. Damage figures are as reported by the National Weather Service at the time, not adjusted for inflation.
