An intense thunderstorm on Wednesday afternoon in the Upper Blue Mountains saw large hail stones at Leura and significant flooding in Katoomba.
NSW SES volunteers responded to 25 calls for assistance in the Katoomba area, the majority for water entering properties.
Blue Mountains SES unit commander John Hughes said the main concern was for water entering Blue Mountains Hospital.
“Fire and Rescue NSW were in attendance at the hospital for a fire alarm and assisted hospital staff to clear storm water within the hospital, whilst SES volunteers cleared the external drainage systems of the hospital,” he said.
There were also several calls for tree damage from lightning strikes, and SES teams and contractors were still dealing with incidents on Thursday.
Buses replaced trains between east-bound between Mount Victoria and Springwood into Wednesday evening due to flooding and landslip damaging rail infrastructure near Katoomba.
