Northborough is seeking volunteers to help run an emergency shelter should the need arise. Extreme weather in recent years resulted in some prolonged power outages, and officials said a better plan to aid residents is needed. Using public safety personnel and town staff left them overburdened, and adding volunteers is essential to run shelters. Anyone who would like to consider volunteering should e-mail firstname.lastname@example.org or call Town Clerk Andy Dowd at 508-393-5001 or health agent Jamie Terry at 508-393-5009.
