Marine heat wave off California helped fuel Hurricane Hilary
Last week, a massive marine heat wave sitting roughly 60 miles off California’s coast oozed eastward, providing warm water fuel for Hurricane Hilary and its historic trek north. It was a worrisome development for researchers who have monitored this warm mass for nearly a decade — and who are watching a developing El Niño in the equatorial Pacific. Ever since the “blob” appeared in the northeastern Pacific at the very end of 2013 — a massive marine heat wave that gripped the West Coast for nearly two years in heat and drought; disrupting marine ecosystems up and down the coast — a massive offshore heat wave has appeared nearly every year (with the exception of 2017 and 2018); expanding in the summer and shrinking in the winter.
