In 1906...a thunderstorm produced north winds sustained to 52 mph and 0.53 inch of rain in 10 minutes. In 1912...a heavy thunderstorm cloudburst in the late afternoon combined with a similar storm to the south of the city to produce widespread flooding on Cherry Creek in downtown Denver...which resulted in two deaths and several injuries. The flooding was the worst since 1864 and covered around 3 square miles of lower downtown. Bridges along Cherry Creek were washed out and water lapped at the floor of the Broadway bridge over the South Platte River...causing authorities to declare it unsafe except for pedestrians. By nightfall... Union Depot was under 2 to 3 feet of water...and railroad and street car traffic was stalled. Those forced from their homes by the surging flood waters took refuge in the Denver Auditorium. The flood waters caused great damage to the sewerage system...parkways...bridges and residences and commercial warehouses near Cherry Creek in the wholesale district. Flood damage was estimated at several million dollars. Heavy thunderstorm rainfall of 2.00 inches...of which nearly 1.75 inch fell in 30 minutes in central Denver... was accompanied by severe thunderstorm winds sustained to 55 mph with gusts as high as 74 mph. In 1933...thunderstorm rainfall was only 0.01 inch...but northwest winds sustained to 37 mph with gusts to 47 mph produced a dust storm for about 10 minutes during the late afternoon. In 1967...heavy rain flooded areas of north and west metro Denver...and high water closed street intersections in the city. Crops were damaged...and 200 chickens drowned by flooding northwest of Denver where farm buildings and irrigation facilities were also damaged. In 1969...a thunderstorm wind gust to 51 mph was recorded at Stapleton International Airport. In 1975...heavy rains caused locally heavy flash flooding along Niver Creek south of Thornton and in other parts of north metro Denver. Over 40 thousand dollars in damage to public property was reported...and numerous homes and yards were damaged. In 1986...thunderstorm winds blew down a power line in west- central Jefferson County. The storm...as it moved into Denver...snapped tree limbs and damaged a fence near Washington Park. Wind gusts in the area were estimated at 80 to 85 mph.

In 2001...a severe thunderstorm dumped hail to 3/4 inch in diameter in the foothills about 10 miles northwest of Golden. In 2011...severe thunderstorms in the Denver metropolitan area produced very heavy rain...large hail and damaging winds. The strong winds toppled a few trees and the heavy rain caused street flooding and minor flash flooding. Several cars were stranded at the intersection of Santa Fe Drive and Oxford...and near Broadway and U.S. Highway 285. A 16-yr old teenager was seriously injured when he tried to retrieve a ball along the banks of West Toll Gate Creek. He was pulled from the swollen creek and died several days later. Hail up to 1 inch in diameter was reported around the area. The thunderstorms also produced frequent lightning. One strike sparked a fire at Aspen Academy...a private school in Greenwood Village. Most of the damage was confined to the roof and attic. In Englewood...a 40-ft tree was blown into a house and knocked down some power lines. At Denver International Airport...a severe thunderstorm produced sustained winds of 47 mph and a peak wind gust to 68 mph. In 2019...a Denver man was killed and his wife injured after he was struck by lightning when they were hiking near the Bear Peak West Ridge Trail. The man was likely hit from a direct lightning strike to his upper body. His wife was not directly hit...but injured by the electrical current from the strike that hit her husband. 14-15 In 1985...from the 14th into the 15th...thunderstorms dumped heavy rain and hail at numerous locations along the Front Range from Denver north.
