“We’re still going to be monitoring this. As much as we saw a clearing of the skies this morning, there is still some risk we will see storms as we head into the afternoon.”
Next week is also set to be a wet one for NSW, as a low pressure system moves across the country from the north-west.
Weatherzone warned that heavy rain, thunderstorms and flooding would spread across Australia over the next 10 days, breaking the dry in parts of the Northern Territory and Western Australia.
The weather service said the weather would likely hit NSW mid-to-late next week, bringing more rain to the already flooded Murray-Darling basin.
“There is some uncertainty regarding exactly where and how much rain will fall across Australia during the next 10 days,” it said in a statement today.
“However, there is good agreement between forecast models that this will be a significant rainfall event for Australia and part of every state and territory is likely to be affected.
“Numerous severe weather, thunderstorm and flood warnings are likely to be issued across Australia during the next one to two weeks as this event unfolds.”
The State Emergency Service responded to 142 calls across NSW in the 24 hours to 8am today, of which 19 were storm-related jobs in metropolitan Sydney, largely for fallen trees and leaking roofs.
He noted that between 4am and 5am, just over 300 lightning strikes hit the ground within 50 kilometers of Parramatta, and another 550 were recorded in the clouds.
An earlier storm on Tuesday afternoon that was concentrated in western Sydney produced 1700 lightning strikes in just an hour, as well as hail.
Yoska Hernandez, from Weatherzone, said hail was recorded in western and southern Sydney as well as the Blue Mountains, the Illawarra, the Southern Highlands and northern parts of the Shoalhaven.
She said between 2pm on Tuesday and 7am on Wednesday, 65,438 strikes were recorded within the larger 100-kilometer radius of Sydney.
SES spokesman Adam Jones said the agency was worried about a thunderstorm over the Northern Rivers and a possible storm in the south-east of the state on Wednesday afternoon hanging that may bring hail and damaging winds.
He advised people to avoid parking under trees.
“With the heavy winds, we are reminding the community that with the earth as sodden as it is, it really creates a risk of trees falling down.”
The SES was still helping flood-hit communities in inland NSW, he said, including the still isolated north-west town of Wee Waa.
Rural properties were also cut off by floods along the Macquarie, Lachlan, Bogan, Gwydir, Namoi and Culgoa rivers. Some farmers had been cut off for weeks.
“In all of these areas, we’re seeing rural isolation and the NSW SES is assisting those farmers in moving livestock, feeding livestock, and resupplying the farmers themselves as well.
“They’re resilient people but the prolonged nature of this means we’ve had to assist more and more.
“There were no flood rescues overnight, which was fantastic to see after double-digits for the last week or two,” Jones said.
“But as conditions are easing and we’re seeing water move through those [river] systems, there is still risk in these areas and any rain that comes in the next week or so could see flash flooding in any area of the state, so we are asking the community to remain vigilant.”
