Across the Nation

Published December 24 2024

As winter advances across the nation, a variety of climatic conditions and their impacts on snowfall, streamflow, and outdoor activities are observed. Snowpack and reservoir levels vary significantly from one region to another, influencing the availability of water resources and the potential for winter sports.

The Northeast and Pacific Northwest are experiencing substantial snowfall, ideal for ski resorts and outdoor enthusiasts seeking fresh powder. In particular, areas like the Cascade Range in Washington and the mountains of Oregon are receiving notable snow accumulations, which are beneficial for the upcoming spring melt and water supply. However, with the increased snowfall comes a heightened risk of avalanches. Avalanche warnings have been issued in regions such as the Chugach National Forest in Alaska and the Central Oregon Avalanche Center, with considerable danger levels indicating that careful route finding and conservative decision-making are essential for backcountry travelers.

In contrast, some regions are facing drought conditions, reflected in the reservoir and dam reports. For instance, the Maurice River at Union Lake Dam in New Jersey reports streamflow significantly below average, raising concerns about water availability if the trend continues. Similarly, in the Southeast, reservoirs like Lake Sidney Lanier near Buford, Georgia, are experiencing levels above average, potentially leading to dam surpluses if wet conditions persist.

Outdoor recreation, both skiing and river activities, must be planned with awareness of current conditions. Skiers and snowboarders can enjoy fresh snowfall in the Rockies and Appalachian ranges, but should remain vigilant for avalanche risks. On the other hand, enthusiasts anticipating river rafting or fishing should be aware of the varying streamflow rates, which could impact their safety and the health of aquatic ecosystems. Overall, monitoring these varied datasets is crucial for water resource management and ensuring safe, enjoyable outdoor activities throughout the season.

Warnings & Alerts

As we tuck in for the holiday season, a tapestry of severe weather alerts has been draped over the United States, urging residents in affected areas to exercise caution. Alaska finds itself bracing for an unforgiving storm, with the National Weather Service in Fairbanks issuing storm warnings effective through December 30. The northwestern coastal waters are expected to be tumultuous, with significant wind speeds that have the potential to challenge even the most seasoned mariners. Notably, communities along the Alaskan coast should be on high alert and prepare for harsh conditions, as winds whip across the icy waters.

Moving down the West Coast, California has its own environmental ordeal with flash flood warnings in place for parts of the state, including the one issued by NWS Sacramento, where heavy rains threaten to overwhelm water systems and create flash flooding conditions. Residents near The Tejon Pass should be particularly vigilant. Meanwhile, the Pacific Northwest isn't spared; Washington's Skokomish River at Potlatch is under a flood warning, putting the surrounding communities on edge as they monitor rising water levels. In the heartland, Arkansas faces a similar plight with persistent flood warnings for the White River at Augusta, remaining in effect until December 30. These warnings underscore the need for readiness and community support in Little Rock and surrounding areas. As friends share this report, it's clear that the gift of safety and preparedness is paramount this season. Let's keep a watchful eye on the conditions, stay informed, and ensure our neighbors and loved ones are doing the same during these natural events.

Avalanche Outlook

As winter recreation season peaks, the latest avalanche warning data indicates a wide spectrum of risk levels across the nation's mountainous regions. Outdoor enthusiasts should exercise vigilant caution, particularly in areas with heightened conditions. The Central Cascades in Oregon, Summit Lake in Alaska, and Mount Shasta in California are all currently under a "considerable" avalanche danger rating, where careful snowpack evaluation and conservative decision-making are essential for safety. In contrast, various locations such as the Eastside Region in California and ...

Reservoirs & Dams

Across the nation, an assessment of the latest observations reveals a mixed picture of the water storage levels in various dams and reservoirs. Some water bodies are experiencing higher than average storage, while others are facing concerning deficits. For instance, Lake Powell in Arizona, a critical water source for the Southwest, is holding just over half its average storage, indicating ongoing drought conditions. Similarly, Elephant Butte Reservoir in New Mexico exhibits significantly lower storage levels than average, emphasizing the water ...

Snowpack & Snowfall Totals

Winter sports enthusiasts and snow lovers, the latest snow report across the nation brings a flurry of excitement with generous fresh snowfall and promising forecasts for the coming days. The past 24 hours have seen a delightful dusting across key areas, with Mormon Mtn Summit in Arizona taking the lead with an impressive 8 inches of new snow atop a 9-inch base, basking under a mostly sunny sky. Not far behind, Howell Canyon in Idaho, amidst mostly cloudy skies, received ...

Flood Monitoring

Communities across the nation are facing significant flooding threats after the latest observations indicate drastic increases in river and stream flow levels, with some areas experiencing over 1600% above their normal rates. The Pigeon and Nolichucky rivers have seen their normal flow rates skyrocket, posing severe risks to nearby towns and cities. The Middle Pearl-Strong and Greys-Hobock regions are also confronting unprecedented water levels, with the Middle Pearl-Strong's streamflow measurements at over 900% above average. This surge in water levels ...

River Levels

Across the nation, various rivers and stream gauges are experiencing a mix of above-average streamflows and other areas grappling with drought conditions. Some waterways have been significantly swelled by recent rainfall, while others remain parched, revealing a diverse hydrological landscape. For water enthusiasts and researchers alike, the current conditions present a range of implications for outdoor activities, wildlife habitats, and water resource management.

In the southern states, the Mississippi River at Memphis, Tennessee, stands out with a robust streamflow ...

Ski Area Conditions

Skiers and snowboarders looking to hit the slopes can rejoice at the latest snowfall totals and forecasts, which promise powdery conditions in several popular destinations. In Arizona, Mormon Mountain Summit received a fresh 8 inches of snow over the past 24 hours, making it an excellent choice for those in the Southwest seeking nearby winter sports.
