An Arctic air mass moved south from Canada into the northern United States, causing a sharp drop in temperatures. Simultaneously, parts of the Pacific Northwest are coping with slowly receding floodwaters and elevated risks of mudslides and levee breaches. This AP photo gallery documents the cold snap in the north and the waterlogged, vulnerable landscapes in the West.
Photos: Arctic Blast Chills Northern US While Pacific Northwest Battles Flood Aftermath

An Arctic air mass pushed south from Canada into the northern United States, bringing a sharp plunge in temperatures and a blast of cold air. At the same time, communities across the Pacific Northwest are grappling with slowly receding floodwaters and heightened risks to hillsides and levees.
What the Photos Show
This curated photo gallery from AP editors documents contrasting scenes: the arrival of frigid conditions in northern states and the wet, vulnerable landscapes of the Pacific Northwest. Images include frozen streets and fields, swollen rivers and saturated slopes, and efforts by local residents and authorities to shore up defenses against further water damage.
Impacts to Watch: The Arctic influx has led to noticeably colder conditions in affected states, while the Pacific Northwest continues recovery efforts as officials warn about potential mudslides and levee breaches as waters recede.
These photographs capture both the immediate bite of winter air in the north and the lingering consequences of heavy water in the West — a striking visual of weather extremes occurring at the same time.
Browse the gallery for a visual account of how two very different weather threats — extreme cold and lingering floodwater — are affecting communities across the United States.
