It was 30 years ago this week, on June 3, that <a href=\"https:\/\/www.thorntonweather.com\/blog\/thornton-weather\/a-look-back-at-the-most-destructive-tornado-in-denver-metro-history-june-3-1981-thornton-colorado\/\">the infamous Thornton tornado struck<\/a>. This twister still stands as the most damaging tornado to have ever struck the Denver metro area.<\/p>\n<p>26-31<\/p>\n<p>In 1995\u2026a cool period with light morning showers and moderate to heavy afternoon showers and thunderstorms pushed rivers already swollen from mountain snow melt over their banks causing minor flooding. Streams and rivers such as the South Platte and Boulder creek flooded meadowlands\u2026bike paths\u2026roads near streams\u2026and other low lying areas. No significant property damage was reported and crop damage was unknown. Rainfall totaled 1.79 inches at the site of the former Stapleton International Airport and only 1.51 inches at Denver International Airport.<\/p>\n<p>29-1<\/p>\n<p>In 1894\u2026heavy rain combined with snowmelt runoff caused widespread flooding over the South Platte River basin. Rainfall was heaviest in the foothills where 5 to 8 inches were measured over the 4 days. Heavy rainfall west of Boulder flooded mining towns and damaged mining properties. In the canyons above Boulder\u2026railroads and roads were washed out along with many bridges. The floodwaters spread into central Boulder and covered a wide area from University Hill north to near Mapleton Hill to a maximum depth of 8 feet. Many houses were swept away\u2026and every bridge in Boulder was destroyed. A few people\u2026trapped in their homes by the floodwaters\u2026 Had to be rescued. However\u2026the gradual rise of the flood waters resulted in only one death. Boulder creek spread to a width of nearly one mile in the pasture land to the east of Boulder. Extensive flooding on left hand creek north of Boulder washed away railroad and wagon bridges. The heavy cloudbursts caused flooding on bear creek\u2026which washed away bridges\u2026railroad tracks\u2026and structures and destroyed the canyon roadway. Morrison sustained the heaviest flood damage on bear creek. In Denver\u2026rainfall totaled only 1.50 inches on the 30th and 31st\u2026but the heavy rainfall on upstream tributaries of the South Platte River caused the river to rise as much as 10 feet above the low water mark in the city\u2026which caused some flooding of pasture land downstream to a depth of 6 feet near Brighton.<\/p>\n<p>30<\/p>\n<p>In 1875\u2026a windstorm lasting almost all day produced sustained winds to 42 mph.<\/p>\n<p>In 1935\u2026southeast winds sustained to 29 mph with gusts to 34 mph produced a moderate duststorm during the afternoon.<\/p>\n<p>In 1938\u2026heavy thunderstorm rain and hail pummeled downtown Denver during the evening hours.

Street\u00a0flooding was reported at 6th St and Canyon Blvd and at\u00a0Baseline Road. Some cars were stranded in the high water in\u00a0low lying areas and one person reported being trapped in his\u00a0vehicle.<\/p>\n<p>30-31<\/p>\n<p>In 1935\u2026heavy thunderstorm rains overnight caused flash flooding east of the city on both Kiowa and Bijou Creeks\u2026 Resulting in a total of 9 deaths. Most of the damage was on Kiowa Creek where there were more structures. The water rose rapidly during the storm\u2026ripping houses and stores from their foundations and sweeping them downstream.
