El Nino wrecks havoc on U.S. weather

Apparently the current El Nino in the Pacific Ocean is the strongest since 1997-1998 (the years I mentioned that you could see snow-capped mountains ringing the Los Angeles basin all winter. And its effects have already led to one major blizzard on the East Coast of the U.S., and another will be hitting this weekend. Christopher Joyce of National Public Radio gave a great explanation yesterday of El Ninos and their effects on the weather. This would be great review for your exam on Monday.
