ALT Ocean surface temperature time series from the Farallon Islands, showing current water temperatures are exceeding 66F and are over 10F warmer than average--shattering all records for so late in the calendar season and also matching the warmest temperatures ever observed at *any* time of year.
ALT Three maps show ECMWF’s January–March 2027 precipitation forecast across the northeastern Pacific and western North America: the ensemble’s 20th percentile, mean, and 80th percentile. Blue indicates above-average precipitation, brown below average, and white near average, relative to the model’s 1993–2016 baseline. Much of California remains wetter than average even at the 20th percentile. The mean shows a pronounced wet signal across California and the Southwest; the 80th percentile reaches or exceeds 250% of average in parts of this region. Forecast initialized November 1, 2026.
ALT Meteogram depicting predicted precipitation at a point near San Francisco, CA over the next 14 days from each member of the ECMWF ensemble. The average 14-day precipitation is around 4.6 inches (which is a lot for 2 weeks in November!), and the range is from 2.7 to 9.6 inches across the model members.
