  1. Injuries and deaths are for the tornado’s whole path, which may extend beyond this area.
  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.

  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.

  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.

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.

    National Weather Service narrative

    The Missionary Ridge fire began in early June (see the June 2002 Storm Data publication) and was contained on July 17th . The fire destroyed approximately 50 homes and 22 other structures. The fire consumed over 70,000 acres. The cost of fighting the fire exceeded 40 million dollars.

  2. Jul 1, 2002Wildfire$2.5 million
    National Weather Service narrative

    The Valley Fire was ignited by lightning in the Falls Creek area adjacent to the Animas Valley in late June (see June 2002 Storm Data publication). 22 homes in the Falls Creek subdivision were destroyed. The Valley Fire consumed 400 acres and became part of the Missionary Ridge Fire Complex. The complex was contained on July 17th.

  3. Jul 24, 2018Flash Flood$2.0 million
    National Weather Service narrative

    Major flooding, mud and rockslides occurred in the Animas Valley along the Colorado Highway 550 corridor between mile markers 33 and 37. Fast moving flood waters and debris flowed in excess of 6 feet deep in places. About 6 feet of debris blocked Highway 550. The highway was closed for approximately 4.5 hours for debris cleanup. The flood waters and debris also flowed across the Durango and Silverton Narrow Gauge Railroad tracks which lead the train to stop and, as a result of the closure of the highway, about 800 passengers were stranded north of Durango. A section of the railroad track was heavily damaged. Significant damage occurred in the Whispering Pines and Pine Acres…

  4. Sep 7, 2002Flash Flood$1.5 million
    National Weather Service narrative

    Flash flooding was widespread along the east side of the Animas Valley. Very large debris flows accompanied the flash floods. Two large houses in the path of the flows incurred extensive damage. Two mobile homes were knocked off their foundations. And some sheds were heavily damaged or destroyed. Mud, large trees, and boulders the size of cars covered many sections of county roads and residential properties up to 10 feet deep. A six mile section of irrigation canal was completely filled with debris. 750 people were evacuated from the Bar D Chuckwagon restaurant after being trapped for nearly three hours.

  5. Apr 29, 1999Thunderstorm Wind$1.0 million
    National Weather Service narrative

    A thunderstorm which moved up from the south produced strong outflow winds which destroyed or damaged many commercial buildings and houses, especially in the Gem Village area. Thousands of trees up to 2 feet in diameter and 60 feet tall were snapped off, generally 10 to 12 feet above the ground. An aluminum boat was found wrapped around a power pole.

  6. Oct 6, 2006Flash Flood$1.0 million
    National Weather Service narrative

    A persistent fetch of subtropical moisture brought heavy rainfall to La Plata County in southwest Colorado for two consecutive days, October 5th and 6th. The two-day rainfall amounts in the areas of heaviest flooding ranged from 1.99 to 3.51 inches. The first reports of flooding and flash flooding came from the La Plata County Sheriff's office at 1530 MST on Friday October 6th, when flooding had occurred along County Road 250 north of Durango and also near Vallecito Reservoir. In the community of North Vallecito, a 44 foot self contained RV, a cabin, and a shed were carried by the flood waters down Vallecito Creek and totally destroyed, with pieces ending up in Vallecito…

  7. Jul 27, 2021Flash Flood$500,000
    National Weather Service narrative

    Heavy rain washed out a culvert on La Plata County Road 309A near Durango-La Plata County Airport. The road was closed for several days for repair work. The Durango Airport received 1.34 inches of rain with storms that day.

  8. Aug 3, 2002Flash Flood$400,000
    National Weather Service narrative

    Flooding and mudslides occurred in several drainages along County Road 501, on the west side of Vallecito Reservoir, and in the Vallecito community. Five to eight feet of debris covered roads in some locations and 2 to 3 feet of mud and debris flowed into and around several homes and businesses. A car was pushed 35 feet down a road and into a tree.

  9. Jul 23, 2002Flash Flood$400,000
    National Weather Service narrative

    Flash floods with heavy debris content cascaded across County Road 240, near where the road intersects with County Road 243. A wall of water 12 to 15 feet high came roaring down Shearer Creek. Further down the road from Shearer Creek, five vehicles (four with occupants) were swept off the road and into flooded streams. The flash flood waters were accompanied by large trees up to 2 feet in diameter and boulders up to 4 feet in diameter. Debris up to 8 feet deep was deposited on the road and private properties. Debris four feet deep covered a bridge. At least one house was damaged and a parked truck was heavily damaged. The force of the water and debris tore out a 50 foot section of…

  10. Nov 8, 1998Winter Storm, Animas River Basin/Durango And Vicinity$300,000
    National Weather Service narrative

    A cold and moist Pacific trough produced the first major winter storm of the season for western Colorado. 8 to 24 inches of snow fell in most mountain areas. 6 to 10 inches accumulated in most lower elevation areas of west-central and southwest Colorado. Some of the largest snow totals included 25 inches at Telluride, 24 inches at Purgatory Ski Area, 24 inches at Molas Pass and Coal Bank Pass, 24 inches as Aspen Ski Area, 19 inches near Ouray, 17 inches at Fort Lewis, 16 inches at Crested Butte, 15 inches near Pagosa Springs, and 15 inches on the Grand Mesa. Windy conditions produced areas of blowing a drifting snow in the mountains. A gust to 67 MPH was measured on the mountains…
