The drumbeat of monster hurricanes in the Pacific has broken a record for nasty long-lasting storms east of the international date line, turbocharged by nature's supersized El Nio, scientists said.

"Since September 20th, when Odalys formed, it's been berserk," said Colorado State University researcher Phil Klotzbach, who forecasts and studies storm activity.

"This year just everything that forms is just lasting a long time and getting really powerful." One of the key measurements meteorologists use to judge hurricane seasons is called accumulated cyclone energy, or ACE, which includes a storm's wind speed and longevity.
