A Connecticut emergency-communications official says Bridgeport Mayor Joe Ganim shouldn't have used an emergency alert system to blast United Illuminating over its response to Tropical Storm Isaias.
The alert prompted hundreds of people to opt out of future notifications.
The Connecticut Post says it obtained the letter from statewide emergency telecommunications director William Youell under the Freedom of Information Act.
Youell urged the city to review its emergency notification procedures but didn't impose any penalties.
Ganim told The Post that city officials "greatly appreciate" Youell's input.
