September weather in Colorado is typically tranquil and one of the more pleasant months in the state.  This week however that wasn’t the case, especially yesterday when severe thunderstorms rumbled across the parts of the state.

Tuesday and Wednesday brought heavy rains to parts of the northern Front Range.  The precipitation was welcomed as it provided much-needed relief from the recently dry conditions.

Yesterday in Colorado Springs and La Junta thunderstorms brought hail that accumulated up to 6 inches deep.  Mother Nature however held more surprises as she brought tornadoes to other parts of the state.

Three tornadoes were reported in northeastern Colorado – one each in Adams, Douglas, and Weld counties.  None of the three caused any damage.

A fourth twister however occurred in southern Colorado near Del Norte in Rio Grande County northwest of Alamosa.  Local resident Julie Sauvigne captured amazing video of the tornado as it ripped through her property causing EF0 level damage to her home.

Watch the video below.  Notice how the visible funnel is almost directly above Sauvigne while the circulation on the ground was occurring in a field nearly a mile away!

NASA satellite image reveals Waldo Canyon Fire’s burn scar

The Waldo Canyon Fire near Colorado Springs became a raging inferno and one of the most disastrous in Colorado history.  New satellite imagery released by NASA shows the massive area burned by the blaze and provides perspective as to just how close it came to the state’s second largest city.

Officials are hoping to announce 100% containment of the fire later today.  The blaze has burned 18,247 acres, the 11th largest in Colorado history.  More notably however the blaze claimed two lives and destroyed 346 homes making it the most destructive wildfire in the state’s history.

From NASA:

The Waldo Canyon Fire was first reported on June 23, 2012, burning in Pike National Forest, three miles (5 kilometers) west of Colorado Springs. Fueled by extremely dry conditions and strong winds, it had burned 18,247 acres (74 square kilometers) by July 5. The blaze severely damaged or destroyed 346 homes, making it the most destructive fire in Colorado history. Mountain Shadows, a neighborhood northwest of the Colorado Springs city center, experienced some of the most severe damage. According to an analysis conducted by the Denver Post, the combined value of the homes that burned to the ground in the neighborhood was at least $110 million.

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on the Terra satellite acquired this view of the burn scar on July 4, 2012, when the fire was still burning but was 90 percent contained. Vegetation-covered land is red in the false-color image, which includes both visible and infrared light. Patches of unburned forest are bright red, in contrast with areas where flecks of light brown indicate some burning. The darkest brown areas are the most severely burned. Buildings, roads, and other developed areas appear light gray and white. The bright red patches of vegetation near Colorado Springs are golf courses, parks, or other irrigated land.
