NSW storms: whopper hailstones hit Hornsby
Severe storms hammered parts of Sydney's on Saturday, inlcuding Hornsby where Fairfax photographer Nick Moir was battered by golf ball-sized hailstones.
Sue Pritchard, a spokesperson for SES, said suburbs in Sydney's north-west, such as Kellyville and Rouse Hill, as well as the areas around St Ives and Hornsby, were worst affected by the severe weather conditions. Hail the size of golf balls was reported in both areas.
"There was lot of damage due to hail such as broken skylights, damage to vehicles, roof tiles broken and trees coming down. The damage looks pretty similar to yesterday's except the big hail seemed to be the feature of today's storms.
"Our volunteers have been smashed really hard because they still had jobs from yesterday to finish and will likely still be working on jobs tomorrow," Ms Pritchard said.
SES had over 630 calls for assistance of Saturday alone.
Residents are being urged to be mindful of the state of their properties to avoid any avoidable damages to their homes during this storm season.
"For our volunteers it's usually that people don't clear out their gutters and then water begins to flow into their house, which can cause a lot of heartache. Also it's good to check your roof tiles after storms and heavy winds because often people don't realise tiles are cracked until the next heavy downfall.", Ms Pritchard said.

Earlier Saturday afternoon, several severe storms amassed throughout eastern New South Wales.
At 3.15pm a severe storm was detected at Bowral, which has now passed. Three sisters in their sixties were hit by lightning while they were sitting together on a bench in Corbett Gardens.
Two of the women have been treated for shock, and one woman is expected to be airlifted to Sydney to be treated for severe burns.
A storm that formed in Penrith, and a later one in Berowra, moved quickly towards the coast causing large hail and heavy rains in Sydney's northern suburbs.
"There have been really strong steering winds pushing the storm in, quit deep easterly winds have stretch it out all the way to the coast in some form," said BoM meteorologist Jordan Notara. "Although we haven't seen reports large hailstones on Sydney's coastal fringe."
A further storm that moved from Maitland into Newcastle caused heavy rains over, Australian band, JET's performance at the Bruce Springsteen concert held in the Hunter Valley.The Bureau of Meteorology cancelled its severe thunderstorm warning at 7.30pm on Saturday night. General thunderstorm warnings are still in place for the Northern Tablelands, and areas surrounding Scone, Tamworth, Armidale and Tenterfield where damaging winds are and heavy rainfall are expected in the next several hours.
Sydney's weather on Sunday is expected to be mostly dry and overcast.
Following the significant damage caused by Friday's severe weather, about 8000 homes and businesses were still without power on Saturday morning, the majority of which were on central coast, a spokeswoman for Ausgrid said.
Pockets of Palm Beach and Avalon would likely be without power until Sunday, while small numbers of residences and businesses on the central coast would have to wait until Monday to turn on the lights.
