(CNN) A bomb cyclone is taking shape along the Eastern Seaboard, and power is being knocked out in the Northeast.

More than 320,000 customers in multiple states were without power early Thursday morning as the coastal storm battered the region, according to poweroutages.us.

Massachusetts alone had more than 136,0000 customers in the dark. Thousands of outages were also reported in surrounding states, including more than 39,000 in New York, 44,900 in Connecticut, 35,000 in Rhode Island and 26,600 in Pennsylvania.

Rain is falling across the region and winds are picking up speed and are forecast to last through Friday. The National Weather Service has issued a flash flood watch for about 7 million in the Northeast and a wind advisory for more than 60 million in 14 states stretching from the Appalachians in North Carolina all the way through Maine.
