Rescue crews responded to Crane Beach yesterday around 4 pm after two women, in their 60s or 70s, were struck by lightning.
Lifeguards were performing CPR to the women when rescue crews arrived.
An initial investigation shows that the women were in the water when the lightning struck as a storm popped up very quickly.
The women had no pulse when rescue workers arrived on scene and were taken to Beverly Hospital.
Before arrival at the hospital, each woman had a pulse restored.
The patients were then taken to Massachusetts General Hospital in Boston and are in critical condition.
The town of Sandwich still had 123 power outages Sunday morning as a result of the storms, and power was restored by 7:15 a.m.
