Northwest just finished warmest fall on record, scientists report
Warm storms caused rain instead of snow, resulting in the lowest Northwest snowpack since 2001 and deep deficits in Oregon and southern Washington, NOAA reports.
- On Monday, the National Oceanic and Atmospheric Administration reported August–November this year was the warmest on record across Oregon, Idaho, Washington and western Montana, with the lowest snowpack since 2001.
- Warm storms produced rain rather than snow at higher elevations, melting snowpack, and with no El Niño this year, NOAA and NASA scientists note more above-normal years consistent with broader warming.
- In the last month, western Oregon had 50% of its normal precipitation while western Washington's record rain only partly refilled overdrawn local reservoirs.
- Communities and water managers face increased drought pressure as snowpack fails to build, undermining summer water supplies and snowmelt-dependent reservoirs in Oregon, Idaho, Washington, and western Montana.
- In the coming weeks, forecasts show cooler, wetter systems could help pull the Northwest out of drought if temperatures drop enough for rain to become snow, Brad Pugh said.
