553 first-hand accounts of flood events in Colorado, ranked by impact. Each is a NOAA-written narrative of the moment.
As high pressure spun southeast of the Four Corners region, subtropical moisture moved northward along the western periphery of the high. This increase in moisture produced some thunderstorms with heavy rainfall in La Plata County.

Read the full account →An area of heavy rain developed across western El Paso County flooding many areas. Rock Creek, Cheyenne Creek, and Fountain Creek experienced flash flooding and flooding. Rock and Cheyenne Creek watersheds experienced significant damages to infrastructure.
Read the full account →Abundant subtropical moisture paired with weak steering flow resulted in slow moving showers and thunderstorms across the higher terrain of western Colorado.
Read the full account →Severe thunderstorms produced damaging wind and hail, along with torrential rainfall across the I-25 Corridor and Northeast Plains. Areas hardest hit included: eastern Boulder, Douglas, eastern Larimer, Washington and Weld counties.
Read the full account →One flash flood occurred on Coal Creek during the early morning hours. A nearby spotter measured 5 inches of rainfall during the event. In the next event, a flash flood reportedly produced 3 feet of running water.
Read the full account →Heavy rainfall associated with a thunderstorm in the Cameron Peak burn area, produced flash flooding in Masonville. Heavy rainfall, up to one inch in an hour, produced flash flooding along Buckhorn Road, south of Big Bear Road.

Read the full account →Above normal temperatures accelerated snowmelt from a near-record snowpack. This resulted in high and fast flows on several rivers and drainages across Western Colorado.
Read the full account →Significant clearing late in the morning resulted in the development of high instability across western Colorado. This, paired with upper level support and ample moisture, produced strong to severe thunderstorms across the area in the late afternoon and early evening hours.

Read the full account →Remnants from Tropical Storm Harold lifted across the Desert Southwest. This, combined with already abundant subtropical moisture, resulted in widespread showers and thunderstorms across western Colorado. Storms were slow moving and produced heavy rain.
Read the full account →Slow moving thunderstorms produced hail and heavy rainfall as they slowly drift south across the east/southeast part of the Denver Metro area. Additional storms track across Colorado producing hail up to 1 inch in Fairplay and Platteville.

Read the full account →Heavy rain, with amounts between 3 and 6 inches, swelled the Monument Creek and Fountain Creek watersheds to overflowing the evening of the 29th.
Read the full account →Numerous strong to severe storms occurred, producing hail up to the size of golf balls and strong winds. Areas of very heavy rain occurred across portions of Custer, Pueblo, Otero, Bent, and Prowers Counties.
Read the full account →Flash flooding occurred along Buckhorn Creek with impacted several sections along Buckhorn Road (LCR 44H). Numerous washouts were observed along Buckhorn Rd. from Ballard Rd to mile marker 30. An estimated 2-3 foot surge of water and debris was reported along Buckhorn Creek.
