HARTFORD -- A Category 3 hurricane with winds of over 110 miles per hour could knock down 70 to 80 percent of Connecticut's trees and paralyze the state for more than a month.

The governor's task force on the effects of Tropical Storm Irene got the sobering facts Tuesday from state and federal officials who said another Category 3 hurricane similar to the infamous 1938 storm is inevitable and requires advanced planning.

Glenn Field, warning coordination meteorologist for the National Weather Service, told the panel that a Category 3 hurricane comes every 69 years, with the last such storm in 1954.

"What we've seen with Tropical Storm Irene is nothing compared to a major hurricane," said Doug Glowacki, a state emergency program specialist.
