Across the Nation

Published December 15 2025
As the United States grapples with a confluence of severe weather events, Alaskans are bracing for an onslaught of storm warnings issued across the state, with the National Weather Service in Anchorage placing the Northern Gulf of Alaska Coast, including Kodiak Island, under multiple advisories effective through December 16. Meanwhile, the Pacific Northwest is battling rising waters, with Washington State under a series of flood warnings by the NWS Seattle, affecting the Cedar River at Renton and Skagit River near Mt. Vernon. Oregon hasn't been spared either, as the Yakima River at Kiona remains a concern. On the other side of the country, the aftermath of heavy snowfall blankets western Pennsylvania, while New Jersey recounts its biggest snowstorm in four years. New York and Delaware are tallying their own significant snow deposits, as residents face the challenges of snow-laden roads and services. Amidst these extreme conditions, the nation's focus also turns to wildfire risk mitigation, with Idaho launching utility projects to bolster resilience. As atmospheric rivers herald new flood concerns and Canada marks a record wildfire season, the U.S. is a tableau of climate challenges, with communities from the Hill Country to King County navigating the immediate threats of floods and the longer-term specter of wildfire and hurricane recovery efforts.

Reservoirs & Dams

Across the nation, a diverse array of dams and reservoirs play a crucial role in water management, providing resources for irrigation, hydroelectric power, and recreation, while also serving as important flood control systems. However, the health and levels of these water bodies are subject to a myriad of factors including weather patterns, climate change, and human consumption. The latest observations reveal a complex picture of surpluses and deficits, signaling the need for continuous monitoring and adaptive management strategies.
