380 NOUS45 KBOU 260859 PNSBOU COZ030>051-262300- Public Information Statement National Weather Service Denver/Boulder CO 259 AM MDT MON AUG 26 2024 ...Today in metro Denver weather history... 19-30 In 1875...grasshoppers appeared in great numbers at 10:00 AM on the 19th and continued through the 30th. Thousands landed on the ground. The streets were literally covered with them. Swarms of grasshoppers were seen on each day. All gardens in the city were devastated...and in the countryside the grasshoppers were very destructive to ripened grain. On the 30th the grasshoppers were so numerous as to almost darken the sun. 24-26 In 1910...the lowest temperature ever recorded in August...40 degrees...occurred on the 24th...25th and 26th...as well as on August 22...1904. The unusually cold weather for so early in the season brought sub-freezing minimum temperatures to much of the Colorado northeastern plains. 26 In 1944...one of the most destructive hailstorms in the city in a decade caused damage estimated at nearly one million dollars. The storm occurred within a period of 10 to 30 minutes...between 2:00 PM and 3:00 PM. The hail varied in size from very small to as large as 1 1/2 inches in diameter. Hail covered the ground to a depth of 5 to 6 inches in some sections of the city. Several people were cut by broken glass. The hail and heavy rain flooded underpasses to a depth of 6 feet...and the occupants of stalled autos had to be rescued. Sewers were unable to handle the sudden amount of water and water backed up and flooded a number of basements. A few first floors of buildings were flooded. The Water Department had a busy time replacing manhole covers that had been displaced by the water pressure. Trees were stripped...one was severely broken...and telephone lines were downed. Roofs...windows... automobiles...awnings...and gardens were severely damaged. Flowers and gardens in some sections of the city were a total loss. Greenhouses were extensively broken with an estimated 20 carloads of glass shattered. Vegetable and truck crops in and around the city were severely shredded. The next day the American Red Cross was designated by the War Agency to grant any and all priorities needed to obtain materials and supplies to replace and repair the damage. In downtown Denver...the thunderstorm produced 0.95 inch of rain and heavy hail along with sustained northwest winds to 25 mph. In 1961...strong winds blew in the walls of a warehouse under construction in Denver. Two workmen suffered a fractured foot and body bruises. In 2014...two men in central Denver were struck by lightning as they sat under a tree to avoid a heavy downpour. One of the men was unconscious and had no pulse when emergency responders arrived. He was immediately taken to Denver Health was listed in critical condition. The other victim suffered less severe injuries. He was treated at the scene and hospitalized...then released a few hours later. 26-27 In 1980...overnight from the 26th to the 27th...two strong thunderstorms hit Arvada and Westminster...dumping up to 1.50 inches of rain in less than an hour. At least two streets were washed out and a number of homes and cars were damaged when a creek flooded. Three homes in Arvada sustained minor lightning damage. $$
