...WINTER STORM TO BRING STRONG WINDS AND HEAVY SNOWFALL TO THE FRONT RANGE MOUNTAINS AND EASTERN PLAINS... .A strong storm will move across the state Monday night and Tuesday. Precipitation will begin as rain across the lower elevations and then switch to snow Monday night with all snow by Tuesday morning. Snowfall forecast for areas along and north of I-76 is highly uncertain due to the storm track and when the change over to snow occurs. Very windy conditions are also expected to develop with this storm with gusts to 60 mph possible over the eastern plains. The strong winds and snowfall will produce considerable blowing and drifting snow with blizzard conditions possible. The worst conditions are expected to be south of Denver over the Palmer Divide and also east of Denver on I-70. Travel in these areas may become very difficult to impossible due to the blowing and drifting snow. For the mountains, snow forms Monday afternoon and will possibly be very heavy late Monday afternoon and evening as the main storm crosses the state. Snow is expected to continue through Tuesday, though the intensity is expected to lighten up. Winds to 60 mph over the higher passes are expected to produce blowing and drifting snow. * WHAT...Heavy snow and blowing snow possible. Total snow accumulations between 4 and 10 inches possible. Wind gusts as high as 60 mph may produce significant blowing and drifting snow. * WHERE...Castle Rock, Byers, Limon, Southern Lincoln County, and Akron. * WHEN...From Monday evening through Tuesday afternoon. * IMPACTS...Snow covered roads will make travel hazardous, with the possibility of very difficult or impossible travel. Visibility may be near zero at times resulting in white out conditions. Travel will be treacherous and potentially life-threatening.

The Snake River is a major river in the United States, stretching over 1,000 miles from Wyoming to Washington, and is a tributary of the Columbia River. The river has a storied history, serving as a vital transportation route for Native Americans and later European settlers. Today, the river is heavily utilized for hydroelectric power, with several large dams and reservoirs along its length, such as the Hells Canyon Dam and the Jackson Lake Dam. These dams have transformed the river into a major source of energy for the region, but have also had significant impacts on the river's ecology and the surrounding landscapes. Additionally, the Snake River and its reservoirs are popular recreational destinations, offering activities such as fishing, boating, and camping. The river also plays a critical role in the region's agricultural sector, providing irrigation for crops and supporting the livelihoods of many farmers and ranchers.

The Snake River is a major river of the greater Pacific Northwest region in the United States. At 1,078 miles (1,735 km) long, it is the largest tributary of the Columbia River, in turn the largest North American river that empties into the Pacific Ocean. The Snake River rises in western Wyoming, then flows through the Snake River Plain of southern Idaho, the rugged Hells Canyon on the Oregon–Idaho border and the rolling Palouse Hills of Washington, emptying into the Columbia River at the Tri-Cities, Washington.
The Snake River drainage basin encompasses parts of six U.S. states and is known for its varied geologic history. The Snake River Plain was created by a volcanic hotspot which now lies underneath the Snake River headwaters in Yellowstone National Park. Gigantic glacial-retreat flooding episodes that occurred during the previous Ice Age carved out canyons, cliffs and waterfalls along the middle and lower Snake River. Two of these catastrophic flooding events, the Missoula Floods and Bonneville Flood, significantly affected the river and its surroundings.
Prehistoric Native Americans lived along the Snake starting more than 11,000 years ago. Salmon from the Pacific Ocean spawned by the millions in the river, and were a vital resource for people living on the Snake downstream of Shoshone Falls. By the time Lewis and Clark explored the area, the Nez Perce and Shoshone were the dominant Native American groups in the region. Later explorers and fur trappers further changed and used the resources of the Snake River basin. At one point, sign language used by the Shoshones representing weaving baskets was misinterpreted to represent a snake, giving the Snake River its name.By the middle 19th century, the Oregon Trail had become well established, bringing numerous settlers to the Snake River region. Steamboats and railroads moved agricultural products and minerals along the river throughout the 19th and early 20th centuries. Starting in the 1890s, fifteen major dams have been built on the Snake River to generate hydroelectricity, enhance navigation, and provide irrigation water. However, these dams blocked salmon migration above Hells Canyon and have led to water quality and environmental issues in certain parts of the river. The removal of several dams on the lower Snake River has been proposed, in order to restore some of the river's once-tremendous salmon runs.
