Clouds of snow and ice roar down Mount Everest. Watch the stunning video below. (YouTube / Jost Kobusch)
As the death toll from Saturday’s massive magnitude 7.8 earthquake in Nepal continues to climb, a stunning video has emerged showing an avalanche striking the Mount Everest base camp.
The video, taken by German climber Jost Kobusch, was discovered on YouTube yesterday.
In it, climbers preparing for their ascent of the world’s highest peak first get a sense something is amiss when the ground starts rumbling. Soon, a massive wall of snow is seen coming down the mountain and engulfing the videographer.
While Kobusch survived, at least 18 other climbers on the mountain died. Overall the death toll from the earthquake has reached nearly 3,800, most of whom perished in Nepal.
On the mountain, the Khumbu Icefall, the primary way up the mountain, has been blocked. Hundreds of climbers and their Sherpa’s were trapped at the higher camps and are now being evacuated by helicopter.

April 19 to April 25: This week in Denver weather history
This week in Denver weather history is one to truly showcase the incredible variety of weather Colorado can receive. Major snow storms, high winds, warm temperatures in the 80’s and even three reports of tornadoes – one near Thornton 21 years ago – have all been seen this time of year.
From the National Weather Service:
17-19
In 1920…snow fell across the city continuously for 57 hours… From the early morning of the 17th until 11:40 am on the 19th. The heavy wet snowfall totaled 18.2 inches with the greatest accumulation on the ground of 12 inches. Winds during the storm were strong with sustained speeds in excess of 27 mph for over 40 consecutive hours…which created near-blizzard conditions. The highest recorded wind speeds were 44 mph with gusts to 50 mph from the north on the 17th and 39 mph with gusts to 48 mph from the northwest on the 18th. The strong winds piled the snow into high drifts which stopped all Denver traffic. Railroads were blocked with only one train entering the city on the 19th. All interurban trains were blocked…as were the 13 trolley lines. Thus…many workers were unable to get home at night and filled all of the downtown hotels to capacity. No grocery or fuel deliveries were possible… Except milk and coal to hospitals and to families with babies. No lives were lost in the city…but several people perished in surrounding districts. Stock losses were heavy on the plains. Temperatures during the storm were in the 20`s.
18-19
In 1884…a major storm dumped 13.8 inches of snowfall on downtown Denver. Most of the snow…10.0 inches… Fell on the 18th. Light rain on the early morning of the 18th changed to heavy snow at 8:00 am and became light after 2:00 pm but continued until 4:00 am on the 19th. The snow melted nearly as fast as it fell. There were only 3 inches on the ground early on the morning of the 19th.
In 1941…heavy snowfall totaled 8.4 inches over downtown Denver. Northeast winds were sustained to 17 mph.
In 1993…sporadic high winds occurred across metro Denver. Significant wind gusts included 97 mph at Rollinsville… 80 mph in southwest Boulder…and 55 mph at Stapleton International Airport. The strong winds snapped a pine tree top…about 15 feet long and 8 inches in diameter… Which crashed through the roof of a church in Evergreen…causing one thousand dollars in damage. Wind gusts of 50 to 60 mph caused structural damage to 3 homes under construction in Broomfield. Northwest winds gusted to 55 mph at Stapleton International Airport.
In 1995…the second spring storm of the month dumped heavy snow in the foothills. The upslope flow along with areas of thunder snow dropped 6 to 12 inches of snow in the foothills west of Denver and Boulder. Snowfall totaled 4.6 inches at the site of the former Stapleton International Airport…but most of the snow melted as it fell. East winds gusted to 29 mph at Denver International Airport on the 18th.
18-20
In 1966…sub-freezing temperatures caused thousands of dollars in damage to fruit trees across metro Denver. Minimum temperatures were in the teens each morning and failed to reach above freezing on the 19th. The low temperature of 13 on the 20th set a new record minimum for the date. Snowfall totaled 5.7 inches at Stapleton International Airport during the period.
19
In 1899…northwest winds were sustained to 48 mph with gusts as high as 60 mph in the city.

In 1963…the second windy day in a row produced west- northwest wind gusts to 52 mph at Stapleton Airport.
In 1971…a tornado occurred in the southwest corner of Weld County about 10 miles west-northwest of Brighton. The storm moved through a farm yard damaging equipment and structures. The strong tornadic winds lifted a stock tank over 2 fences into a corral 150 feet away. Later…a tornado touched down briefly west-southwest of Buckley Field…8 miles southeast of Stapleton International Airport. No damage was reported.
In 1985…high winds occurred in the foothills. Winds gusted to 97 mph atop Squaw Mountain in the foothills west of Denver. West winds gusted to 37 mph at Stapleton International Airport.
In 1987…a powerful cold front produced high winds and engulfed metro Denver in huge clouds of blowing dust that lowered the visibility to as little as 100 yards. The cold front generated winds as high as 72 mph at Brighton…67 mph in Thornton…and 54 mph at Stapleton International Airport. Winds of 50 to 70 mph were common along the Front Range from Denver north. The high wind gusts flipped a light plane taxiing at Stapleton International Airport…slightly injuring two people on board. The cold front dropped the temperature from a high of 80 degrees at 3:00 pm to a low of 33 degrees at midnight. Nearly an inch of snow…0.8 inch… Fell at Stapleton International Airport before midnight.
In 1988…a tornado touched down in Fort Lupton… Following a path 50 to 75 yards wide for 2 1/2 blocks. The twister damaged roofs on 2 schools and broke numerous windows; about 10 houses were damaged and several cars had windows blown out. Several trees were downed.

The high winds blew the chimney off the roof of a house in Westminster. Numerous homes received minor shingle damage. Some of the stronger wind gusts included: 98 mph at Jefferson County Airport in Broomfield…91 mph atop Squaw Mountain west of Denver…and 75 mph atop Table Mesa near Boulder. West northwest winds gusted to 45 mph at Denver International Airport.
In 2001…westerly Chinook winds… Gusting as high as 40 mph at Denver International Airport…prevented the low temperature from dropping below 51 degrees…setting a new record high minimum for the date. The high temperature of 77 degrees was not a record.
In 2005…severe thunderstorms produced large hail across metro Denver. Hail as large as 1 1/4 inches in diameter was measured in Arvada. Hail to 1 inch in diameter fell in Westminster…Northglenn… And Thornton. Hail to 7/8 inch was reported near Brighton…Barr Lake… And Castle Rock. Hail to 3/4 inch fell in Elizabeth and Broomfield and near Golden…Brighton… And Fort Lupton.
19-20

19-21
In 1984…a large snowstorm buried most of Colorado under a thick mantle of wet snow. Total snow amounts ranged from 10 to 20 inches across metro Denver and a whopping 20 to 40 inches in the adjacent foothills. The snow closed roads and damaged electrical transformers…causing numerous power outages. Nearly 14 inches (13.6) of snow fell at Stapleton International Airport where the combination of snow and wind closed all but one runway…resulting in the cancellation of many flights. Both I-70 and I-76 were closed to the east of Denver.
19-22
In 1933…a major storm dumped 16.8 inches of snowfall over downtown Denver when rain changed to snow during the early morning of the 20th and continued through midday of the 22nd. Most of the snow fell on the 21st. Due to melting… The most snow on the ground was 10.5 inches at 6:00 pm on the 21st. Before the snow started…a strong cold front on the evening of the 19th produced north winds sustained to 35 mph with gusts to 37 mph. The strong winds deposited a thin layer of dust on the city.

Northeast winds gusted to 24 mph at Denver International Airport. The storm also brought unseasonably cold weather with 5 new temperature records equaled or broken. Record low temperatures of 8 and 6 occurred on the 11th and 12th. Record low maximum temperatures of 20…19…and 30 occurred on the 10th…11th… And 12th respectively. This was also only the second time on record that the temperature had failed to reach the freezing mark for 3 consecutive days in April.
10-14

In 1967…microburst winds gusted to 51 mph at Stapleton International Airport.
In 1982…wind gusts to 60 mph were reported in and near the foothills. Wind gusts to 44 mph were recorded at Stapleton International Airport.
In 1987…snow fell over metro Denver… Causing traffic tie-ups on the roads and at Stapleton International Airport where some flights were delayed for 90 minutes. I-25 south of Denver was closed for a time due to numerous traffic accidents. While only 4.2 inches of snow fell in Denver… Foothills to the southwest received 6 to 12 inches of snow. North winds gusted to 33 mph at Stapleton International Airport where the maximum snow depth on the ground was only 2 inches due to melting.
12-13

Only 1.9 inches of snow fell at Stapleton International Airport where northeast winds gusted to 32 mph on the 13th. Most of the precipitation from the storm fell as rain across the city with 0.62 inch of precipitation measured at Stapleton International Airport.
The month of March was relatively uneventful and lacked any sort of real weather drama. What was notable was the dry conditions and unseasonably warm temperatures that dominated for the most part.
March started out considerably colder than normal with the first five days of the month seeing temperatures around 20 degrees below normal. A light shot of snow was recorded on the fourth of the month, a reading that would be our biggest snowfall for the period.
Temperatures began to turn warmer on the sixth with above normal readings recorded through the 16th of the month. We even managed two 80+ degree days on the 15th and 16th.
Denver actually saw its earliest 80 degree reading in history on the 16th. The previous earliest 80 degree reading occurred on March 18, 1907.
Unsettled conditions interrupted the warmth on the 25th with a light snowfall and colder temperatures.
We then bounced right back to the dry, mild conditions for the balance of the month.
Thornton’s average temperature for the month came in at 44.9 degrees. This was well above the long term Denver average of 40.4 degrees. Out at DIA, the Mile High City’s reading was very similar at 45.0 degrees.
Temperatures in Thornton ranged from a high of 82.6 degrees on the 16th down to a low of 9.2 degrees on the 5th of the month. At the airport, Denver’s maximum for the month of 81 degrees came on the 16th with its lowest of 2 degrees on the 5th.
Denver officially broke two temperature records in March 2015. On March 6th the high temperature of 79 degrees broke the record high for the date (previously 76 degrees set in 2013). Also, on the 16th, the high temperature reading of 81 degrees was a record (previously 75 degrees in 2012).
In terms of precipitation, the rain bucket totals fell well short of the March average of 0.92 inch. Here in Thornton a mere 0.49 inches was recorded while Denver saw quite a bit more with a measurement of 0.79 inches.
March is historically our snowiest month but that was certainly not the case in 2015. Thornton snowfall totally only 2.8 inches and Denver was at 2.9 inches. Both were well below the average of 10.7 inches.

In 1911…north to northwest winds were sustained to 42 mph on the 4th and to 41 mph on the 5th.
In 2002…a whitish-colored haze engulfed metro Denver on both days. The haze was the result of a huge wind storm that kicked up dust and sand from the Gobi desert in Mongolia and China during the latter half of March. Westerly winds aloft transported the dust cloud across the Pacific Ocean and over the western united states…depositing some of it on Colorado.
In 2009…a blizzard developed over the northeast plains of Colorado. Most of the urban corridor was spared from the blizzard…with the exception of eastern Adams and eastern Arapahoe counties. The combination of strong wind and heavy snow snapped 14 power lines along State Highway 36… Near Strasburg. In Arapahoe County…7 poles were snapped in Bennett. Interstate 70 was closed in both directions east of Denver. At Denver International Airport…a peak wind gust of 63 mph was observed from the north…breaking the previous record of 62 mph established in 1986.

In 1988…a wind gust to 74 mph was recorded at Rollinsville. West winds gusted to 35 mph at Stapleton International Airport.
In 1990…a heavy… Wet snow fell in many areas in and along the Colorado Front Range. Snowfall amounts of 4 to 7 inches were common around the Boulder area with lesser amounts elsewhere. Only 2.0 inches of snow fell at Stapleton International Airport where north winds gusted to 28 mph. Icy roads contributed to numerous fender-benders and a 20-vehicle pileup near the junction of I-70 and I-25 in the city.
In 2000…high winds developed in the Front Range foothills… From about I-70 northWard. Peak wind gusts included: 83 mph at the National Center for Atmospheric Research in Boulder…75 mph near Louisville… And 70 mph at the National Wind Technology Center…south of Boulder. West winds gusted to 41 mph at Denver International Airport.
In 2005…a surface low pressure center deepened over eastern Colorado and produced damaging high winds across metro Denver. The strong wind gusts ranging from 50 to 70 mph damaged roofs and fences. Cross-winds blew several empty semI-trailers on their sides along I-70 and I-76 east of Denver. Peak north wind gusts included: 60 mph near Bennett and Keenesburg…59 mph near Brighton… And 53 mph at Denver International Airport. Over the Palmer Divide south of Denver…the high winds combined with heavy snow to produce blizzard conditions. Snowfall accumulations ranged from 3 to 8 inches over eastern Douglas and western Elbert counties. Snowfall totals included: 8 inches at Sedalia…4 inches near Castle Rock… And 3.5 inches near Franktown.
5-6
In 1939…3.0 inches of snow fell in downtown Denver. North winds were sustained to 34 mph on the 5th and to 26 mph on the 6th. The strong winds caused considerable drifting of snow. Several highways leading into the city were closed during the height of the storm due to poor visibility. Streets and highways became coated with ice in places. The temperature dipped to 11 degrees early on the 6th. This was the coldest reading of the month that year. Most vegetation was not far enough advanced to be injured by the cold temperatures…although a few buds froze on early shrubbery.

The month of March is the start of meteorological spring and while conditions do begin warming, winter weather is certainly out of the question. From hot to cold, snow to rain, the conditions can be very conducive to great pictures as we see in our slideshow.
March in Denver typically means frequent and rapid weather changes. The days grow longer and we start enjoying more sunshine and sometimes summer-like weather. However, on occasion arctic air masses can still force their way south into Colorado dropping temperatures quickly and markedly.
