Columbia Hit by La Nina

    Months of heavy rains, flooding and mudlsides have caused "the worst natural disaster that we can remember," Columbia's president said Monday night. Three million Columbians have been badly affected by heavy rains since the middle of last year. More than 400 people have been killed by the recent bout of rains, flooding and mudslides. 88 have died in 2011 alone.  
     The adverse weather conditions, known as La Nina, have been classified as the strongest in history. La Nina is associated with colder-than-normal water temperatures in the Pacific Ocean, in contrast to El Nino, which refers to unusually warmer waters.
