MAITLAND received its most significant rainfall in 10 months - which saw roads flooded and facilities closed - after a dumping of more than 130mm over the weekend.
A torrent of rain and wind battered the region with a whopping 137mm recorded at Maitland Aiport between Friday and Monday.
Hunter Valley Grammar School was closed on Tuesday after the storm left the school with extensive damage while Melville Ford Bridge also closed due to high water levels.
The city's State Emergency Service received more than 60 call-outs for flash flooding, fallen trees and leaking roofs.
Maitland SES spokesperson Alex Varley said the service received 35 calls for assistance in the East Maitland, Ashtonfield and Metford areas on Monday.
She said over the weekend most calls were for leaking roofs but this time it was more varied with branches down, flash flooding and intense storm damage.
"From reports we received from residents, the intensity of the cell was similar to some east coast lows in terms of damage," Ms Varley said.
"We had crews from all over the Hunter helping out. We were trying to triage but it was difficult to triage when they were all priority."
Ms Varley said the Melbourne Street underpass was also underwater for a while, but it did subside reasonably quickly.
Maitland City Council also closed East Maitland Aquatic Centre due to flooding, but the pool reopened on Tuesday morning.
It follows a big weekend for the SES, which Ms Varley said was unusual for the service in the current climate.
"So far this season we've been doing a lot of bushfire support, so this was a bit of a wake up call," she said.
