There are reports of significant damage in the Kurri Kurri business district as a huge thunderstorm moves through the area.
The Kurri Kurri Community Centre in Lang Street has been evacuated after suffering storm damage this afternoon.
The damage is yet to be fully assessed and so it will be closed until further notice. There are reports the roof has been torn off the centre and exposed bricks have fallen onto the road.
Glen works next door to the library and says emergency services are checking that everyone got out alright.
"Community Centre library has lost its roof completely by the look of things its taken some of the facade down with it. There's bricks all on the road, tin across the road. At the moment we've got ambulance, fire, police, the streets are blocked off, we've got wires down, trees down..."
