The split-flow pattern will have varied impacts across U.S. regions. The Gulf Coast and Southeast face elevated flood risks from frequent storms, while California is at risk of significant flooding due to atmospheric rivers and already full reservoirs. The Great Lakes and Northern Plains will experience milder, drier winters, potentially leading to reduced snowpack and spring drought risks. The Pacific Northwest and Northern Rockies are expected to see below-average precipitation, which could impact water supplies. The Eastern Seaboard may experience increased storm activity and cold-air intrusions by late winter. Globally, the event is projected to contribute to record-breaking temperatures in 2027, with significant economic and agricultural disruptions.
