The strongest wind gust recorded was mph at Wondervu, a record for that normally windy spot. Elsewhere, speeds reached mph at Buckhorn Mountain, at Waverly, and 92 at Boulder.
Ironically, Chinook winds can be accompanied by beautiful cloud formations, called lenticular clouds, that appear smooth and sculpted , as shown in the top image.

For many in the Northern Hemisphere, the month of March means a heralding of spring, warmer temperatures, and longer daylight. On the morning of May 28, , thousands of people across the southeastern United States gathered to witness a rare and. Observations of nighttime lights are reaching their sunset at NCEI. The product, along with several others from the Visible.
However, the rare total solar eclipse crossing the country on. Published January 31, Animated nature rejoices. There are quite a few famous folk tales and legends associated with the Chinook winds. One common thread in some native legends is that the warm air blows on the ridges to warn or send a message to people.
Another story , with Albertan origins, is about a man who rode his horse to church, only to find snowdrifts piled so high, only the steeple stuck out of the snow. So, he tied his horse to the steeple with the other horses, and used a snow tunnel to get into the church. Upon his return, a few hours later, all the snow has melted, leaving the unfortunate horses dangling from the church steeple. An EF1 is a moderate tornado with winds from miles per hour.
An EF2 is a significant tornado with winds from miles per hour. Before its power failed in the maelstrom, the Earth System Research Laboratory measured a mile per hour wind gust on January 17, The National Center for Atmospheric Research measured in southwest Boulder measured a mile per hour wind gust on its rooftop feet above the city. Fifty homes were rendered uninhabitable. Twenty small planes at Boulder Municipal Airport were destroyed.
Thousands were left without power when utility poles snapped. Tens of thousands of acres of farmland in Boulder County suffered erosion damage. A study found an anecdotal correlation between migraines in 13 patients and Chinooks, but could not prove any statistical correlation. The goal of the study, as reported in the Journal , was to determine if there was any relationship between sinonasal anatomy and chinook headaches. The study analyzed 38 patients who reported chinook-related headaches and 27 control patients with no reported Chinook-related headaches.
CT scans identified variations in the sinus anatomy of patients who reported Chinook-related headaches. The study determined that anatomical variants may predispose patients to facial pain and pressure by blocking the natural sinus ostia. That blockage prevents proper pressure equilibrium. A study of strokes analyzed wind speeds, temperatures, humidity, and barometric pressure over a five-year period compared to the number and type of strokes in the same period.
The authors found no correlation between Chinooks and the type or number of strokes experienced. Soil can lose its moisture and its mass as water and soil are carried away by the high-speed winds, according to Mountain Nature. Trees and other plants may wake up from their winter hibernations early only to become dehydrated if they survive the rapid temperature fluctuations. And while the Chinook winds can melt the snow, uncovering grass for grazing animals, they can also melt the insulation provided by the snow that is protecting hibernating animals, according to Mountain Nature.
There have also been incidences of cattle coming down with illnesses, and some cattle have been electrocuted after wire fences became electrified due to strong positive electrical charges in the air. According to the Weather Doctor , fire risk increases with the Chinook winds because of the heat and arid conditions. The slightest spark can cause a major wild fire. Two fires in the same area around Boulder County, Colorado, burned 19 years apart and both were fueled by the Chinook winds, according to Boulder County.
The first Olde Stage Fire in , fanned by mph winds, burned about 3, acres 1, hectares , destroying 15 buildings and damaging many others. The second Olde Stage Fire in also burned about 3, acres while being fueled by mph winds. Several buildings were destroyed and many others threatened.
Chinook winds have been blamed for increases in several medical conditions including migraines, strokes, and even sudden infant death syndrome. But the research has not resulted in clear evidence of a correlation. Several studies have attempted to correlate migraine occurrences with the Chinook winds. In a small study in , published in the journal Headache, researchers analyzed the diaries of 13 migraine patients in Calgary, Alberta.
The probability of migraines was slightly greater on days with Chinook weather than on days without Chinook wind, and older patients were more likely to get migraines on those days.
