An overnight drenching has dumped more than 50 millimetres of rain on Sydney’s CBD and surrounding suburbs, delivering the Harbour City’s wettest day since February.
And the wet and windy conditions are expected to persist throughout Wednesday, with the city’s east expected to bear the brunt of a low-pressure system off the NSW coast.
Isolated thunderstorms could hit the city’s east during Wednesday morning, while the Bureau of Meteorology is forecasting about another 20 millimetres of rain to fall through the day.
The “feels like” temperature dipped to an icy 2.9 degrees in the city at midnight as winter made its presence felt, before heavy rain started hammering down a short time later. The heaviest falls set in at 12.30am in the city, and continued throughout the early hours of the morning.
Bureau of Meteorology figures show that, at 6.30am on Wednesday, 52.2 millimetres of rain had fallen on Sydney’s CBD since 9am on Tuesday.
Sydney’s heaviest falls were recorded in Little Bay in Sydney’s south-east, which recorded 54 millimetres in the same time, while Chatswood recorded 50 millimetres, and Bondi 45 millimetres.
“It’s the heaviest day of rain we’ve seen [in Sydney] since February, so it’s been quite a few months since we’ve seen rain this heavy,” Weatherzone meteorologist Kim Westcott said.
It was a different story for residents in Sydney’s west, where rainfall totals were more moderate. Richmond and Badgerys Creek recorded 16 millimetres in the same time and Bankstown recorded 18 millimetres.
Debate swirls about the nature of the complex weather system and whether it will count as an east coast low. Ms Westcott described the system as a low on Wednesday morning.
“This low has brought quite windy conditions, and also quite heavy rain towards the east, and it will continue to do so today. The wind will ease as the low moves away but the rain will hang around,” Ms Westcott said.
“Today we could see potentially heavy falls, and these falls will be along the beaches and eastern suburbs. Generally the western suburbs will be much drier, although they will still see some rain today.”
The heaviest falls are expected to ease from Thursday, although showery conditions are expected to hang around until Sunday.
Wet long weekend
“Friday and into the weekend, we still could see some rain, so it’s not going to be completely clear sailing, although there are indications there will be a lot more drier spells then there will be today,” Ms Westcott said.
According to the bureau, regions from the mid-north coast northwards are likely to cop the biggest soaking over the coming week.
The bureau’s eight-day forecast map (see below) points to the potential for falls of as much as 200 millimetres along the coastal fringe, with even heavier falls just offshore.
