In the words of Cardi B and Megan Thee Stallion, grab a bucket and a mop for some wet-ass weather, because some parts of Australia’s east are expected to cop 200mm of rain this week.
While Australia’s east has been blessed with some darn good sun lately, it appears it’s all coming to an end, with the Bureau of Meteorology (BoM) warning that a fast-moving coastal low can bring in a big drenching.
For folks who are not sure what an “east coast low” is, it can be identified as “an intense low-pressure system that forms quite quickly” near the coast. According to Weatherzone, factors including warm sea surface temperatures, baroclinic instability, a block high-pressure system and an upper trough over the Great Dividing Range can contribute to the intensification of an east coast low.
Speaking to ABC News, BoM’s community information officer, Daniel Hayes, also says that the devastating impact these east coast lows have is what makes them stand out.
“To be an east coast low, it has to bring with it high-impact weather,” Hayes told the publication.
“So, something bringing extreme rainfall, storm-force winds and large waves.”
The incoming east coast low could be the first to hit Sydney in three years.
According to BoM’s Steve Bernasconi, the low is “deepening” off the north coast and will likely escalate this evening, meaning it could bring in some serious rain and damaging winds.
It’s been forecast that 50 to 120mm of rain could pelt the east, south and mid-north coast of NSW, and some isolated showers could bring down 200mm, 9News reports.
“It’ll bring widespread impacts. The position and the strength of the low will determine the duration and the severity of the impacts, which may persist into Thursday,” Bernasconi said.
As the coastal low escalates, NSW SES has urged residents to stay vigilant and prepare for severe weather conditions, such as flash flooding.
The BoM has also issued severe weather warnings for NSW’s Mid North Coast and parts of Hunter, Metropolitan, Illawarra, Northern Tablelands and South Coast Forest Districts.
“A rapidly deepening complex low-pressure system is forecast to develop a vigorous Coastal Low offshore of the Mid North Coast overnight tonight, before it slowly tracks southwards during Tuesday. Winds are forecast to strengthen along the coastal fringe from Tuesday morning, extending to the northern ranges and their eastern lee slopes from Tuesday evening,” the BoM wrote in its alert.
While the rain is forecast to stay from Tuesday to Wednesday, Sydney is expected to cop the heaviest rain tomorrow, with 90mm of rain forecast to fall in 24 hours.
