The sometimes-ferocious rainstorms that hit California in March were likely the beginning of the end for El Nino, as the warm ocean system that produced a wet winter in many parts of the West is continuing to fade.

Any storms that remain on tap this spring will likely be mild and not contribute much to seasonal precipitation totals, experts say. “Now that we’re into the spring months, widespread rain events will become less and less likely as we transition into our ‘spring shower and thunderstorm’ season,” National Weather Service warning coordinator Michelle Mead said in an email.
