Hurricane Wilma knifed through Florida with winds up to 125 mph Monday, shattering windows in skyscrapers, peeling away roofs and knocking out power to 6 million people, with still a month left to go in the busiest Atlantic storm season on record. At least six deaths were blamed on the hurricane in Florida, bringing the toll from the storm's march through the tropics to 25. After a slow, weeklong journey that saw it pound Mexico's Yucatan Peninsula for two days, Wilma made a mercifully swift seven-hour dash across lower Florida, from its southwestern corner to heavily populated Miami, Fort Lauderdale and West Palm Beach on the Atlantic coast, The Associated Press reported. The insurance industry estimated insured losses in Florida at anywhere from $2 billion to $9 billion. Officials said it was the most damaging storm to hit the Fort Lauderdale area since 1950.
