California: state of emergency declared due to severe storm. Nearly 700,000 homes were without electricity Monday morning.

Dozens of flights departing and arriving at Los Angeles airport were canceled or delayed. This storm, with gusts of 100 km/h or more, is part of a meteorological phenomenon called “Pineapple express” which originates in Hawaii, near a tropical humidity zone. The west coast of the United States endured an unusually wet winter last year, due to a series of closely spaced storms that brought near-record rainfall.
