      Thursday will be a day few Portenos will forget.

      A toxic cloud from a port fire hung over central Buenos Aires...until rains washed it away.
      Officials said a cargo container of insecticides and pesticides from China...bound for Paraguay...had caught fire.
      There were rumors the thick dense smoke contained mercury...but port officials denied it.
      Some flights were cancelled...and a motorway was closed.

       Then...heavy rains finally cleared the air...but also flooded streets...sweeping away cars...and even causing power outages.
