Pacific Northwest: El Nino Winter Outlook
Precip: drier · Temp: warmer · Moderate confidence
The same southward jet-stream shift that floods California typically starves the Pacific Northwest of its usual storm track, producing a warmer, drier winter with a below-normal mountain snowpack -- the opposite lean from California on the same weather system.
If you ski or ride in the Cascades, this is the region where El Nino historically 'loads the dice' against you, not for you. It's a tendency, not a lock -- some El Nino winters still deliver good high-elevation snow -- but the honest baseline going into this event is below-normal snowpack odds.
Historical strong-event comparison
How this exact region behaved in the strongest recent El Nino winters -- not a national average.
| Event | What happened here | Source |
|---|---|---|
| 1997-98 | Well below-normal Cascades snowpack and a warm, dry winter across Washington and Oregon. | NOAA CPC composite analysis |
| 2015-16 | One of the warmest, lowest-snowpack winters on record in the Cascades, compounding an already low-snow pattern from the prior year. | NOAA CPC / NRCS snowpack records |
| 1982-83 | Warmer and drier than normal, consistent with the canonical El Nino PNW composite. | NOAA CPC composite analysis |
