Hundreds of people across Brooklyn are without power Monday morning as utility crews work to restore electricity following winter weather that moved through the area.

According to Con Edison’s outage map, 803 customers across the borough were without power as of Monday. The largest clusters were reported in Williamsburg, where 144 customers are affected, followed by Ridgewood with 142, Crown Heights with 118, and Borough Park with 118 customers also in the dark.

In Williamsburg, some blocks have electricity, while others do not. Utility trucks were parked along side streets as crews worked block by block to identify problems and make repairs.

Con Edison says most of the outages appear to be weather-related. When snow melts and mixes with road salt, that water can seep into underground electrical equipment and cause damage, sometimes forcing crews to shut off power for safety reasons.

Firefighters also responded to several manhole incidents across the borough overnight. Officials say that kind of activity can happen when water gets into underground electrical systems.

For residents, the outages mean dark apartments and, for some, a lack of heat. Utility crews say they are working as fast as they safely can to restore service.

Con Edison encourages customers to check the outage map online for updates as repairs continue.
