Westchester County Executive Andrew Spano yesterday announced a plan to hook county residents up to information about possible emergencies via their e-mail and text messaging. Spano said residents who sign up would be able to receive information about major storms or some other disaster, including what they might need to do or where they should go. The system would supplement county information distributed through the media and other outlets.
