Pepco is sending out robocalls today, warning area residents of “the very real possibility of power outages” this weekend.

Residents should expect restoration to take several days, the call warns, and customers were urged to prepare for lack of electricity.

The utility suggests listening to the news or going to its own Web page; the robocall doesn’t suggest it, but you can also call 877-PEPCO-62 (877-737-2662).
