A commotion for Wyoming nursing home residents overnight, as rooms were flooded by the brief but intense thunderstorm lashing at parts of the Coast.
Fire and Rescue Crews and the SES headed to Henry Kendall Aged Care on Kalawarra Avenue around 9:30pm, mopping up and sandbagging the place.
No one was injured.
It was just one of many jobs emergency services attended to as lightning zapped the region.
A house in Holgate, a garage in Woy Woy and a gas main in Berkeley Vale all went up in flames after being struck by bolts.
Regarding the Holgate incident, it's understood lightning struck a fuse box, starting a small electrical fire at the Katandra avenue property.
Inspectors say it was quickly extinguished, and while there were no reported injuries the house has suffered pretty serious electrical damage.
The cell also wreaked havoc with our trains, damaging overhead wiring at Hawkesbury River Train Station stopped services between Gosford and Hornsby for several hours. Services are running as normal as of this morning
Plenty of rain too: around 60mm of rain fell at Mt Elliot, while Gosford was next in line with a sizeable 40mm, 27 of them in the space of just half an hour after 8:30pm.
While the weather event laos cut power to about 4,000 homes overnight - around 200 and businesses in the Somersby and Mangrove Mountain areas are still without electricity.
Ausgrid expects to get them back on the grid by 11:00am.
The SES says it received 18 callouts for help, mostly for leaking rooves, flooded properties and water over roads.
