UPDATE: City increased estimate of number of customers without power Sunday evening.

The mayor's office reports some 5,000 11,000 NStar customers in Boston are without power and that it's "possible that some outages could last days."

Meanwhile, city crews received roughly 500 reports of downed trees and tree limbs across the city (including this one in Roslindale).

The Boston Fire Department reports firefighters responded to calls across the city, but especially in West Roxbury, Roslindale, Jamaica Plain and Allston-Brighton.
