Terrifying videos capture man’s escape from California wildfire
Colorado has been extremely fortunate this summer with no truly notable wildfires. Other locations across the western U.S. have not been near as lucky. Highlighting this are videos taken by a northern California man as he fled the fast moving Valley Fire.
The Valley Fire broke out Saturday afternoon and quickly exploded forcing thousands to evacuate with little or no notice. Yesterday, California Governor Jerry Brown declared a state of emergency for Lake and Napa counties. As of this morning the blaze had already consumed 61,000 acres and firefighters only had 5% containment.
A YouTube user posted three videos yesterday showing a harrowing escape down roads in the Anderson Springs and Middletown areas. As he drives, flames burn, oftentimes reaching 10 or more feet into the air, lap the roadway and embers and debris blow across the road.
Watch the terrifying videos below.

Thornton’s September preview: Typically on of our most pleasant months
Following on a drier and slightly warmer than normal August, the month of September arrives and one can’t help but wonder if an early fall lies in wait. The month can bring our first snow of the season but more often than not, it is one of the most pleasant along the Colorado Front Range.
As temperatures start to drop, September usually reminds us that summer is at an end and fall is now here. Sunshine is predominant though as the month actually has the highest percentage of sun out of any month. Sunny days and clear, cool nights are the standard weather pattern for the month.
The month can bring extremes however. We will of course forever remember last year’s devastating floods brought on by record-setting rain. Longtime residents might remember September 1971 which brought over 17 inches of snowfall.
Get a complete look at September’s weather and more details as to what we can expect this year here.
August 2015 weather recap: Month saw near normal temps, below average precipitation
High pressure was the dominant feature across much of Colorado during the month of August 2015. This helped keep temperatures quite warm and while there were occasional storms, they failed to deliver much in the way of precipitation.
We started out the month very warm and dry. This was interrupted on the 9th when a series of disturbances finally brought some measurable precipitation. Dry weather returned for a few days but then a strong cold front moved bring much cooler temperatures from the 17th to the 19th. The break was short-lived and warmer mercury readings and drier conditions dominated the balance of the month.
Thornton’s average temperature for the month came in at 71.8 degrees, not far off Denver’s long term average for August of 72.5 degrees. Out at DIA where the Mile High City’s official readings are taken, it was much warmer with an average of 74.0 degrees.
Temperatures in Thornton ranged from a high of 98.1 degrees on the 15th down to a low of 45.3 degrees on the morning of the 19th. Denver’s maximum reading of 98 degrees came on the 15th as well and its lowest reading of 43 degrees came on the 23rd.
We saw 18 days with high temperature readings above the 90 degree mark. Denver saw one more than that.
Two daily high temperature records were tied in Denver during the month, those coming on the 18th and 26th with readings of 98 and 97 degrees respectively. Additionally, two mornings in a row fell to record lows. The record low temperature for the 18th (47 degrees) was tied and the following day a new record low of 47 degrees was set.
In terms of precipitation, a paltry 0.87 inches fell in Thornton’s rain bucket. Out at the airport, Denver recorded 1.18 inches. Both were well below Denver’s long term average of 1.69 inches for August.

August 2015 top shots: Monthly photo slideshow

As the calendar turns to August, the summertime heat begins to fade and that makes it easier to get out and enjoy all of the outdoor activities Colorado has to offer. From a walk in a park to afternoon thunderstorms to an abundance of wildlife, photo opportunities abound as is seen in our slideshow.
Our monsoon season typically arrives about now and that means better chances for moisture. However with limited instability, the intensity of storms are more sedate. That doesn’t mean however that the weather is any less photographic.
- Slideshow updated August 30, 2015
By the end of the month some of our seasonal feathered friends will be looking to leave the state giving our last chance to see them till spring. Larger mammals are gearing up for the rut (mating season) and that can make for some intense scenes.

Within days of the U.S. Environmental Protection Agency’s accidental release of 3 million gallons of mining wastewater into the Animas River in Colorado, portions of the Internet frothed over with conspiracy theories that the EPA spill may not have been an accident. Now, that line of thinking has found its way to the Utah legislature. And… Continue reading EPA Spill Conspiracy Theories Gain Traction in Utah Legislature |
