Castle Rock, the town this property stands in, in 96 storm reports between 1993 and 2025: 67 hail, 12 lightning, 8 thunderstorm wind, 4 tornado.
The reports record 6 injuries. Each account below is quoted exactly as the forecast office
filed it, from the NOAA Storm Events Database, and each date
opens the federal record of that event.
Two men were shocked when lightning hit the ground nearby, as they were golfing the eighth green at Castle Pines. The two golfers suffered only minor injuries.
Lightning struck a teenager as he was mowing his lawn and listening to an iPod. The teen suffered burns to his hands and feet, and had blood running from his ear when he was found. The victim's eardrums were ruptured and his hearing was damaged.
Lightning struck a power pole in Castle Rock igniting a small fire and injuring a 12-yr old girl standing nearby. The girl received minor injuries from the electrical shock. Lightning also sparked a small brush fire. The fire was quickly extinguished without incident.
Heavy rain, up to 3 inches in an hour, caused flash flooding problems from Castle Rock to Parker. Interstate 25, north of Castle Rock, was closed as highwaters covered sections of the highway. Some cars were left floating in the floodwaters.
