Hurricane Irene caught schoolteacher Judi Nowottnick by surprise. Although there was no hurricane warning for her neighborhood, the power blinked off at her two-story colonial in Odenton on Aug. 27 and didn’t come back for eight long days. Four dozen crabs and $1,000 of other food in her two refrigerators spoiled, and Nowottnick spent an additional $400 on fast food for her two adult children living at home. But a bigger surprise arrived when she submitted the bill to her insurance company, with which she had taken out a deluxe policy to cover such losses.
