Nation Split: West Floods, East Freezes in Dual Storms

A powerful one-two punch of extreme weather is striking the U.S., forcing dramatic rescues and threatening major disruptions from coast to coast. In the West, a relentless "atmospheric river"—a long, concentrated band of tropical moisture—has caused major flooding. Emergency crews are performing water rescues as the deluge continues. Meanwhile, a separate snowstorm, fueled by a blast of Arctic air, is sweeping from the Midwest toward the East Coast. This system threatens heavy snow and travel chaos. The dual storms highlight a nation grappling with sharply contrasting severe weather events simultaneously. Officials warn residents in both regions to follow local safety advisories.
