Los Alamos, the town this property stands in, in 34 storm reports between 2000 and 2024: 19 hail, 12 flash flood, 1 wildfire, 1 dust devil.
No death or injury is recorded in these reports. 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.
After 1 to 1.5 inches of rain fell on the northern portion of the Las Conchas burn scar, flash flooding was reported in Santa Clara Canyon. Four people that were working in the canyon had to be rescued by helicopter.
Brief heavy rain and strong runoff caused more damage to North Road in Los Alamos where recent drainage upgrades and repairs were washed away. North Road continues to suffer damage with such rapid and high runoff from the burned areas of Pueblo Canyon which have not recovered from last years Cerro Grande fire storm.
Mud, logs and large rocks washed onto State Road 501 (West Jemez Rd.) near State Road 4, as well as in Los Alamos Canyon and along Camp May road. Heavy equipment and road graders were needed to clear the debris.
Newspaper report with images of significant hail damage to a mobile home in Los Alamos. Home owners reported hail was ping pong ball sized. Location is estimated from article giving home address. Time is estimated, based on radar imagery and other hail reports in the area. All images attached to this event are courtesy of the Los Alamos Daily Post newspaper.
Los Alamos Sky Cam and pictures from local residents showed significant accumulations of pea to penny size hail in downtown Los Alamos from a thunderstorm. Hail accumulation depth looked to be around 2 to 3 inches based on tire track marks on the road.
Lightning splintered a tree at the Los Alamos Golf Course near 16 Los Alamos High School Golf Team members and four coaches. The strike occurred at around 4 pm, about 300 feet away from where the team was practicing. Several of the students reported feeling a strong static electricity sensation flow through their bodies. Fortunately, no injuries occurred.
Power outages as well as flooding in the basement at Los Alamos National Labs were reported. An isolated strong cell formed over the area and stayed generally stationary for 2 hours. Rainfall amounts over 1.5 were recorded at sites across LANL.
Water and debris flowed over Highway 501 after approximately one inch of rain fell over central portions of the Las Conchas burn scar. The highway was temporarily closed.
Both Highway 4 and 501 were closed in the Jemez Mountains due to flooding. Heavy rains on the Las Conchas burn scar caused significant runoff and debris flow over the roadways. At least a 50 yard stretch of debris several inches deep was noted along State Highway 501. Both roads had to be cleared by the Highway Department before traffic was allowed to pass.
A brief and intense hail storm with stones ranging form one half inch to one inch in diameter covered city streets and parking lots to a depth of 4 to 8 inches.
