In 2003…one of the worst blizzards since historic records began in 1872 struck metro Denver with a vengeance.  Heavy wet snow accumulating to around 3 feet in the city and to more than 7 feet in the foothills brought transportation to a near standstill.  North winds sustained to 30 mph with gusts as high as 41 mph produced drifts to 6 feet in the city.  The estimated cost of property damage alone…not including large commercial buildings…was 93 million dollars… Making it the costliest snowstorm ever.  Mayor Wellington Webb of Denver said…”this is the storm of the century…a backbreaker…a record breaker…a roof breaker.”  two people died in Aurora from heart attacks after shoveling the heavy wet snow.  The national guard sent 40 soldiers and 20 heavy duty vehicles to rescue stranded travelers along I-70 east of gun club road.  The heavy wet snow caused roofs of homes and businesses to collapse.  The snow also downed trees… Branches…and power lines.  Two people were injured when the roofs of their homes collapsed.  In Denver alone…at least 258 structures were damaged.  In Arvada…a roof collapse at west gate stables killed a horse.  Up to 135 thousand people lost power during the storm…and it took several days for power to be restored in some areas.  Denver International Airport was closed…stranding about 4000 travelers.  The weight of the heavy snow caused a 40-foot gash in a portion of the tent roof…forcing the evacuation of that section of the main terminal building.  Avalanches in the mountains and foothills closed many roads…including I-70…stranding hundreds of skiers and travelers.  Along I-70…an avalanche released by the Colorado department of transportation…blocked the interstate in both directions for several hours.  Several residences between Bakerville and silver plume were evacuated because of the high avalanche danger.  At Eldora Ski Area…270 skiers were stranded when an avalanche closed the main access road.  After the storm ended…a military helicopter had to ferry food to the resort until the road could be cleared.  The heavy snow trapped thousands of residents in their foothills homes in Jefferson County for several days.  Two homes burned to the ground when fire crews could not reach the residences. Some schools remained closed well into the following week. The storm officially dumped 31.8 inches of snow at the site of the former Stapleton International Airport…the most snowfall from a single storm since the all-time record snowfall of 37.5 inches on December 4-5…1913.  The storm made March 2003 the snowiest March on record…the 4th snowiest month on record… And the 5th wettest March on record.  The 22.9 inches of snow on the 18th into the 19th was the greatest 24 hour snowfall ever recorded in the city during the month of March.  The storm was also a drought-buster…breaking 19 consecutive months of below normal precipitation in the city.  Snowfall across metro Denver ranged from 2 feet to more than 3 feet. The highest amounts included:  40 inches in Aurora…38 inches in centennial and 6 miles east of Parker…37 inches at Buckley AFB…35 inches in southwest Denver…34 inches in Louisville… 32 inches in Arvada…31 inches in Broomfield and Westminster… And 22.5 inches in Boulder.  In the foothills…snowfall ranged from 3 feet to more than 7 feet.  Some of the most impressive storm totals included:  87.5 inches atop Fritz Peak and in Rollinsville…83 inches at Cabin Creek…74 inches near Bergen Park…73 inches northwest of Evergreen…72 inches in Coal Creek Canyon…70 inches at Georgetown…63 inches near Jamestown…60 inches near Blackhawk…55 inches at Eldora Ski Area…54 inches 8 miles west of Sedalia…and 46.6 inches at Ken Caryl Ranch. The storm was the result of a very moist…intense slow moving pacific system which tracked across the four corners and into southeastern Colorado…which allowed deep easterly upslope flow to form along the Front Range.

The strong winds did considerable damage to property… Wires…plate glass windows…and indirectly loss by fire.
