ECMWF Sees 70%-100% Odds California Lands in Wettest 20% of Winters

3 articles · Updated · CBS New York · Aug 7

Summary

  • Daniel Swain said ECMWF now points to a “genuinely extraordinary to extreme” El Niño, with 70%-100% odds California gets above-average precipitation this winter.
  • Those same forecasts give 70%-100% odds that December through February ranks in the top 20% of the state’s wettest winters on record, raising flood concerns after an exceptionally hot summer.
  • Southern California coastal residents are already uneasy after recent King Tides brought dangerous surf and damaged berms and other shoreline protections in some cities.
  • NOAA has said the event could rank among the largest El Niños since 1950; the pattern typically makes the southern U.S. stormier, leaves parts of the Midwest drier and keeps the North warmer than normal.
