The death toll in the massive mudslide in Guatemala is likely to climb from dozens to hundreds as hopes for finding survivors faded two days after the disaster struck. At least 85 people have been confirmed dead so far in the mudslide which struck the town of El Cambray near capital, Guatemala City. “The figure we… Continue reading Guatemala Mudslide Death Toll May Soar |
Weather system deluges eastern US coast as hurricane threat eases
|
Sarasota, Florida (dpa) – The south-eastern US coast was likely to be spared the wrath of Hurricane Joaquin, but rainfall from a low pressure system drenched several states Saturday. Flood warnings were posted in several coastal states, reaching accumulations of up to 25 centimetres in already saturated areas. One of the worst hit was South Carolina,… Continue reading Weather system deluges eastern US coast as hurricane threat eases |
Thornton’s October preview: Fall should finally make an appearance
With the first full month of fall here, October usually brings one of the quietest weather months in the Denver area with plenty of mild, sunny days and clear, cool nights.
October is historically the second sunniest month and conditions are generally calm.
However we also will usually see our first taste of winter during the month with the first freeze and first snowfall of the season. Temperatures as well will start to drop and by the end of the month the average nighttime lows are below freezing.
For complete details on our historical October weather and what we can expect in the coming month, read our complete October weather preview here.
September 2015 weather recap: One of the warmest, driest on record
With the mercury stuck stubbornly at the top of the scale and barely a few raindrops falling into the bucket, September 2015 will be going into the books as one of the warmest and driest on record.
High pressure dominated the entire region during the month. This allowed temperatures to consistently climb above normal and helped prevent moisture from arriving in any significant amounts. At Denver International Airport, 27 of the 30 days had above normal temperatures. Thornton’s overall temperatures were cooler than DIA’s but we were still quite a bit warmer than average.
The monthly average temperature in Thornton came in at 67.1 degrees. Out at the airport where the Mile High City’s official measurements are taken, the average was 69.4 degrees.
Denver’s historical average for September is 63.4 so both locations came in well above normal. Officially, September 2015 ranks as the warmest September on record, easily jumping to the number one spot over September 1948 which had an average of 68.3 degrees.
Undoubtedly the big difference between measurements at DIA and other locations in the metro area are yet another example of the airport’s readings consistently being an outlier from the reality seen in more populated areas. This has been an ongoing problem since the National Weather Service moved the official station from Stapleton.
The warmest mercury reading in Thornton during the month was 94 degrees on the 13th. The coldest came on the 19th when temperatures dipped to 40 degrees in the early morning hours. Eight days in Thornton topped out above the 90 degree mark.
At the airport, Denver’s warmest reading of 92 degrees came on September 2. It’s coldest on September 19 (44 degrees). The airport saw seven days with above 90 degree maximums.
Just as the month was exceedingly warm, it also was very dry. Thornton saw a mere 0.09 inches fall in its rain bucket and Denver recorded 0.11 inches. Both were far short of the September precipitation average of 0.96 inches.
DIA’s measurement means September 2015 goes into the books with the 9th least amount of precipitation in September since 1872 (16th driest overall).

September 2015 top shots: Monthly photo slideshow
The month of September is typically one of the more pleasant months in Colorado. Temperatures are usually comfortable and there is not normally a lot of weather drama. That however does not mean there aren’t plenty of photo opportunities.
Wildlife is still quite active along the Front Range and flowers will hold on to their petals for at least the first part of the month. Then of course there is the weather which you never know what to expect. Thunderstorms, heavy rain, and even snow are a possibility.

Tropical Storm Joaquin, Upgraded to Hurricane, May Head to East Coast
|
Tropical storm Joaquin, which some meteorologists expect could be headed toward the East Coast of the United States over the weekend, was upgraded to a Category 1 hurricane on Wednesday morning by the National Weather Service. Joaquin formed late Monday over the Atlantic Ocean and strengthened east of the Bahamas on Tuesday afternoon, with wind speeds… Continue reading Tropical Storm Joaquin, Upgraded to Hurricane, May Head to East Coast |
NASA: Water found on Mars

NASA will announce on Monday that liquid saltwater exists on the surface of Mars – a discovery that scientists say indicates the “potential” for life on the planet. The historic findings by scientists from NASA and several US universities are based on research on dark, narrow and elongated streaks that appear on the surface of the… Continue reading NASA: Water found on Mars |
Taiwan evacuates thousands as ‘super typhoon’ nears

Taiwan has evacuated thousands of residents and tourists as “super typhoon” Dujuan headed towards the island, gathering strength on its approach to the east coast. Torrential rains and high winds are forecast across Taiwan from Monday afternoon, with landfall predicted around 15:00 GMT. Almost 3,000 people, most of them tourists, were evacuated on Sunday from Taiwan’s… Continue reading Taiwan evacuates thousands as ‘super typhoon’ nears |
Supermoon eclipse provides rare celestial event Sunday
A total lunar eclipse coupled with a ‘supermoon’ will bring a very unusual scene to the sky on Sunday. Taken separately, the two events are not quite as extraordinary or rare. However, this will be the first time in 33 years they have occurred at the same time and the last for another 18 years.
The moon’s orbit around Earth is not a perfect circle and when it is at its closest to us, it appears quite a bit larger to our eye – hence the name ‘supermoon.’
On Sunday it will be about 31,000 miles closer to Earth than it is at its farthest point. According to NASA, this results in it appearing to be about 14% larger and 30% brighter.
The total lunar eclipse will be our second of 2015 and fourth in the past two – a tetrad of eclipses. During these, the moon finds itself in the Earth’s shadow and without direct sunlight hitting its surface, the moon turns an eerie orange / red color – a ‘blood moon.’
The last time these two events coincided was in 1982 and the next time won’t be until 2033. As NASA scientist Noah Petro said, “That’s rare because it’s something an entire generation may not have seen.”
When and where to watch?
The partial eclipse begins at 7:07pm MDT on Sunday, September 27, 2015 with totality starting at 8:11pm. The moon will then be completely eclipsed for a little more than an hour with mid-eclipse at 8:47am. The waning partial eclipse will end at 10:27pm.
One catch for viewing the entire event here along the Front Range is that when it begins, the moon will actually be just starting to rise on the eastern horizon. However, at mid-eclipse the moon will be 21 degrees above the horizon to the east southeast providing a nice view not far above the landscape.
Anyone in the area with a clear view of the lower, eastern sky should have no problem viewing the event.
Will Mother Nature cooperate?
Our unseasonably warm temperatures will be continuing through the weekend so there are no concerns about it being too cold to go outside. Clouds, however, are something to watch closely for. Some atmospheric moisture is expected late in the day Sunday and it is possible cloud cover may impact the clear viewing.
On the day of the eclipse, check our hour-by-hour outlook for the latest sky cover forecast.
What is the ‘blood moon’ and tetrad?
During totality, the moon will be rendered orange / red as the Earth’s shadow envelops the moon. Many are calling this a ‘blood moon’ but the meaning behind that term isn’t exactly clear.
As written on EarthSky.org, some attribute it to the lunar tetrad – four successive full lunar eclipses without any partial eclipses. Tomorrow morning’s eclipse is the second in the lunar tetrad with each full lunar eclipse coming six months apart.
The blood moon as it pertains to these eclipses should not be confused with the October full moon which is also referred to as a blood moon in folklore.
Fall Foliage 2015: Top spots to view the colors near the Front Range
This time of year many folks head to the hills west of Denver in search of gold – fall foliage gold.
This year the changing of the colors seems to be a bit spotty and an early freeze last fall followed by a late freeze this spring has impacted the overall quality of the show. That certainly is not to say there isn’t some absolutely gorgeous spots out there.
Where to go? Below are five of ThorntonWeather.com’s favorite ones near Denver – plus a few further out and some bonus ideas. After that, we will tell you where you can find a great website that provides regular updates on viewing conditions.
I-70 Corridor – If you’re looking for the easiest route, then this one is for you. Simply head west on I-70 about 110 miles to Avon. Between Vail and Avon, both sides of I-70 are lined beautifully with aspen.
Rocky Mountain National Park – One of the most popular summer destinations in the state is of course also a prime spot to view aspen in all their glory. Once in the park head toward Bear Lake. Glacier Gorge Junction provides a beautiful spot and you of course also get to enjoy all the splendor that Rocky Mountain National Park has to offer. Extend your viewing by taking Trail Ridge Road all the way through to the west side of the park and the Grand Lake and Granby area.
Peak to Peak Highway – This little road trip can be a dual purpose trip – gambling and fall foliage viewing! Take U.S. 6 through Clear Creek Canyon and then 119 through Blackhawk and Central City. You can of course stop there if your wallet is fat enough and donate some money to the casinos. From there continue on 119 toward Nederland. Take highway 72 toward Ward and Allenspark. There you will find more golden aspen than you can imagine, all with the Continental Divide nearby.
Poudre Valley Canyon – Heading north on I-25 take Colorado 14 west and into Poudre Canyon and Roosevelt National Forest. As you continue west you will come very near timberline as you come to Cameron Pass. Amazing views abound!
Guanella Pass – This is a nice, relatively short drive from Denver. From C470 take 85 through Bailey and Conifer, a nice drive unto itself. When you come to the town of Grant, take the Guanella Pass Scenic and Historic Byway north to Georgetown. The air is pretty thin along the way as you climb in excess of 11,500 views through the Pike and Arapahoe National Forests. Fair warning – about 10 miles of the road is gravel but it is well maintained.
A couple other possibilities further from the Front Range:
Leadville / Aspen – From Denver take I-70 west to Copper Mountain and then Colorado 91 south over Freemont Pass to Leadville. Along the way there are plenty of viewing opportunities and Leadville is a nice little town to make a stop. From here you can take Highway 24 north back through Minturn and Vail. To extend the drive, take Highway 24 south to Colorado 82 and head toward Aspen. You can stop by the Maroon Bells in White River National Forest to view some of the most photographed mountains in Colorado.
Cottonwood Pass – From Denver take Highway 285 to Buena Vista. Head west on Main Street for seven miles then west on County Road 344 / Colorado 82. From there you start the climb up Cottonwood Pass with absolutely stunning views from the top. If you are up for it, you can continue down the west side of the pass into the Taylor Park area. Be forewarned though that the western half of the pass is unpaved and twisty.
Honorable mentions worth considering:
- Boreas Pass between Breckenridge and Como (County Road 10)
- Kenosha Pass on Highway 285 between Bailey and Fairplay
- Independence Pass (Colorado 82 between Aspen and Twin Lakes)
- Colorado 103 from Evergreen to Echo Lake. Throw in a drive up Mount Evans for a bonus.
If you do head out, be sure to send us your pictures for inclusion in our monthly photo slideshows!
