Consolidated Edison says power has been restored to more than 80 percent of its customers who were blacked out in the storm.
The utility still had 156,800 customers without power at midday Monday. That included about 68,000 homes and businesses in suburban Westchester County.
Con Edison said it expects to resolve “the vast majority” of the Sandy-related outages by next weekend.
But efforts to get the rest back on line could be hampered by more wet, windy weather expected to hit the coast Wednesday.
Early forecasts were predicting a chance of rain and wind gusts of up to 50 mph.
In the meantime, the utility asks that people who do have power conserve it by refraining from using non-essential appliances, such as washers and dryers.
