"Rita" and "Katrina" in 2005 were the wakeup call. The meteorologists have been issuing preliminary forecasts for the 2006 hurricane season indicating that, like 2005 and 2004, it will be a very active year, with possibly even more numerous really severe storms.
As a final note, both "Katrina" and "Rita" faded their punches as they made landfall, weakened IIRC by cooler nearshore waters cooled by recent rain showers in the coastal areas. "Wilma" was a severe hurricane in south Florida, but fortunately its "dirty side" passed over Florida Bay and largely-empty mangrove swamps in the Everglades; Naples was on the left side of the fast-moving storm and received a double benefit of offshore winds, which militated against the storm surge, and the storm's forward motion, which reduced the top winds experienced in Naples and, by its rapidity, worked against the accumulation of a big tidal surge.
Naples was very, very lucky. If the storm had landed 50 or 75 miles farther north, they'd have been creamed every bit as badly as the Mississippi Gulf Coast was by "Katrina" two months earlier.
