**Updated** Crews working to repair damage, restore power following intense thunderstorm

More than 4,000 customers on the Acadian Peninsula remain without power after a powerful thunderstorm raged across the region Thursday night.

NB Power says the storm caused extensive structural damage on the peninsula, with the bulk of the outages on Lamèque Island.

It appears strong winds cut power poles around Caraquet, while the road to Lamèque was blocked by fallen lines.

The province's Emergency Measures Organization says the bridge between Shippagan and Lamèque could remain closed until Saturday morning.

The bridge has one-lane open for emergency vehicles, allowing for power crews to proceed with repairs.

NB Power says replacement equipment like poles, power lines and structures were sent from Fredericton overnight.

There are currently 20 crews on the ground in the affected areas, and a helicopter is conducting air patrols to assess damage.

Meanwhile, the Vitalitè Health Network says the medical imaging department at the Lamèque Hospital and Community Health Centre, along with Extra-Mural program offices in Lamèque, are closed Friday as a result of power outages.
