Across the Nation

Published November 21 2024

As of the latest data, the national snowpack and avalanche conditions depict a diverse range of scenarios that could influence outdoor activities and water resources in various regions. Snowpack levels are crucial for understanding water supply and flood risks, especially in western states where snowmelt feeds rivers and reservoirs. Meanwhile, avalanche warnings and snow forecasts are vital for outdoor recreation safety, particularly for winter sports enthusiasts.

Starting with snowpack and streamflow conditions, we see varying degrees of snowfall and reservoir levels across the nation. For instance, the LAKE WINNIPESAUKEE AT WEIRS BEACH in New Hampshire shows current gage height at 3 feet, below the average of 3.77 feet, which could indicate lower water levels that may affect local water supply and recreational activities. Similarly, reservoirs like the INDIAN LAKE NEAR INDIAN LAKE NY, with a current elevation of 1641 feet against an average of 1645.22 feet, and GREENWOOD LK AT AWOSTING NJ, currently at 617 feet versus an average of 618.36 feet, are demonstrating minor deviations from their typical readings.

In terms of avalanche warnings, there are currently no significant warnings, but it's essential to stay updated through local avalanche centers, especially for those planning to venture into backcountry areas. Ski areas such as Squaw Valley G.C. in California are expecting substantial snowfall of up to 108 inches, offering excellent conditions for winter sports but also necessitating caution due to potential avalanche risks.

High streamflow levels are reported in various locations, including the Columbia River at Beaver Army Terminal Nr Quincy, OR, with a significant flow of 305,000 cubic feet per second, indicating potential flooding risks and impacting water-based activities. These high streamflow conditions necessitate close monitoring for any changes that might warrant flood advisories or impact dam operations.

In conclusion, the current snowpack, reservoir levels, and avalanche forecasts across the nation highlight the importance of monitoring these conditions for both safety and resource management. While some regions experience typical seasonal readings, others show variances that warrant attention from local authorities and the public. Outdoor enthusiasts, particularly skiers and snowboarders, should heed avalanche advisories and be prepared for rapidly changing conditions. Those relying on water resources from reservoirs should note current levels for potential impacts on usage and conservation measures.

Natural Catastrophes

As floodwaters swell in the heartland, our thoughts turn to the residents of Kansas, where the Cow Creek near Hutchinson remains under a vigilant watch. The National Weather Service in Wichita has extended a Flood Warning until the stroke of midnight on November 22, urging caution as the waters continue to rise. The heart of Florida is similarly besieged by unyielding rain, with the St. Johns River near Astor and the Withlacoochee at US 41 Dunnellon caught in the grip of nature's deluge. These areas, under Flood Warnings issued by the NWS in Melbourne and Tampa Bay Ruskin, are facing a critical period as warnings stretch into the evening of November 21. Floridians are no strangers to the whims of weather, yet each warning is a fresh call to safeguard communities and remain alert.

Out west, Oregonians are bracing for a tempest as a Storm Warning echoes through the coastal regions. The NWS in Portland speaks of daunting seas, forecasting hazardous conditions with waves reaching heights of 11 to 16 feet, potentially impacting maritime ventures and coastal activities until the evening of November 22. Farther north along the Pacific, Washington state is preparing for an even more potent storm, with the NWS in Seattle anticipating southeast winds tearing through at 40 to 50 knots, and monstrous seas of 22 to 27 feet until the early hours of November 23. It's a sobering reminder of the might of the ocean and the need for vigilance. Down in Louisiana, the Calcasieu River near Salt Water Park and Glenmora is the focus of continued Flood Warnings. With the NWS in Lake Charles monitoring the situation closely, communities along these waterways are advised to remain informed and prepared for water levels that may change with little notice. Across these regions, the blend of human resilience and community support is the unwavering counter to nature's unpredictability.

Avalanche Outlook

As winter sports enthusiasts flock to the mountains, it's essential to pay close attention to the latest avalanche warnings to ensure a safe and enjoyable experience. Across various regions, avalanche centers have been monitoring snow conditions closely, providing vital information for those venturing into potentially hazardous terrain.

In the Western United States, the Colorado Avalanche Information Center (CAIC) has issued warnings indicating generally safe avalanche conditions with a 'low' danger level in multiple zones, advising vigilance for unstable snow ...

Reservoirs & Dams

The latest observations of the nation's dams and reservoirs present a diverse picture of water storage levels across the country. Several key reservoirs are experiencing notable fluctuations in their storage capacities, which are critical for water supply, agriculture, hydroelectric power generation, and ecological balance. A general trend can be seen where some reservoirs in the western states are below their historical averages, highlighting ongoing concerns over water scarcity and drought conditions. Conversely, certain reservoirs, particularly in the southeastern region, are ...

River Levels

Rivers across the nation are experiencing a dynamic mix of high streamflows, with some exceeding historical averages, while others remain within the range of seasonal fluctuations. The latest observations indicate that many waterways are reacting to a combination of weather patterns, including heavy rainfall in some regions and ongoing drought conditions in others. For instance, the Columbia River near Quincy, Oregon, is registering a significant flow of 305,000 cubic feet per second (cfs) amid showers and breezy conditions, well above ...

Snowpack & Snowfall Totals
