Deputy zone commander for the Hunter NSW State Emergency Service Peter Green has praised the quick action of volunteers in Wednesday's powerful and concentrated thunderstorm across Newcastle and Lake Macquarie.
When the storm rolled in, Hunter SES teams wasted no time throwing on their orange overalls.
"They they just know they need to be ready," Mr Green said.
"They are all volunteers and they do a fantastic job.
"There was quite a sudden, short burst of operational activity across Newcastle and Lake Macquarie.
"We received in excess of 100 calls for assistance as a result of the short but intense storm that occurred at approximately 4pm yesterday.
"The Newcastle unit responded to over 60 tasks and the Lake Macquaire unit to almost 30."

Mr Green said some parts of Newcastle had received more than 70mm within an hour and that most of the calls for help were for damage to houses from fallen trees, with a few for people impacted by rising water.
There was also one flood rescue request.
"A lot of the major roads carried a lot of water and that affected the flow of traffic," Mr Green said.
"We urge people to not drive through flood water.
"In case of lightning, avoid being outside and, as always, if there's any rising water, don't go into it."
While storm activity can be unpredictable, there are things people can do ahead of time to safeguard themselves and others.
"When it's not raining, go and check your gutters are clear of leaves and debris and make sure things like the guttering system is functioning properly," Mr Green said.
The deputy zone commander said looking out for neighbours who might not be able to climb a ladder and clear their own property would make a big difference.
"This is where being a good neighbour comes in," he said.
"That community spirit goes a long way to general preparedness."
Wednesday's storm was over shortly after it started, but those in the SES are not complacently waiting for the next one.
They are always preparing for what could be around the corner, keeping an eye on Bureau of Meterology forecasts and warnings.
In the two hours following the thunderstorm, six teams from Newcastle and four teams from Lake Macquarie were supported by some neighbouring units and nearby NSW Rural Fire Service brigades.
Mr Green said it was amazing to have support between the services in times of emergency.
"In the recent fires we supported them and for them to reciprocate that is great," he said.
