In a region unaccustomed to serious hurricanes, it is easy to underestimate both the need to evacuate and the difficulty of doing so. But with meteorologists now warning that Irene could be a historic storm on par with Hurricane Carol in 1954 and Hurricane Bob in 1991, both of which wreaked havoc in New York and across New England, it's time to get serious. Evacuations will not be necessary everywhere, but residents need to know whether and when to evacuate, and how to do so quickly if necessary.
