Atmospheric rivers bear down on the West Coast : NPR
NPR • • nation
Key Points:
- The Pacific Northwest is experiencing heavy rainfall due to multiple atmospheric rivers, with two more expected to hit Oregon and Washington on Friday and Saturday, following earlier storms this week.
- Atmospheric rivers are long, narrow bands of water vapor that bring significant moisture and precipitation, responsible for 50-60% of California's rainfall and a major cause of flooding in the Western U.S.
- This year's atmospheric river season is progressing rapidly, compounded by El Niño-related warm ocean waters and coinciding King tides, increasing the risk of coastal and inland flooding.
- Despite common assumptions, research indicates that atmospheric rivers do not directly correlate with El Niño events, and there is insufficient data to link them conclusively to human-caused climate change.
- Residents should remain vigilant as these natural weather patterns continue to bring heavy rain, high tides, and potential flooding hazards along the West Coast.
