A 7,000-mile atmospheric river is stretching from Philippines to the U.S.

A strong-to-extreme atmospheric river will stretch 7,000 miles from the Philippines to the Pacific Northwest this week, bringing significant rainfall, high-elevation snow and strong winds to Washington, Oregon, Idaho, Montana and British Columbia starting Monday.

While atmospheric rivers commonly hit the Northwest during fall and winter, the length of this one is very unusual. Spanning the length of the Pacific, this river in the sky is about three times longer than average and among the longest typically observed on the planet.

Hawaiʻi will see little or no impact; the river will span pretty much all open ocean between the Philippines and Northwest.

Weather models also predict that the amount of moisture this atmospheric river will carry will break December records in pockets of Centra
