Sea foam, gales, and snow on stormy, chilly NSW day

 

The weather in New South Wales is dangerous in a whole new way this Friday, as a wintry bite and gale force winds add to the meteorological mix.

Persistent showers continue to sweep across coastal districts, particularly in the stretch of coast from the Illawarra, south of Sydney, to the Hunter region, north of Sydney. But today’s main threat is the wind.

At 11 am on Friday, the Bureau of Meteorology issued a Severe Weather Warning for damaging winds in parts of the Mid North Coast, Hunter, Sydney Metropolitan, Illawarra, South Coast, South West Slopes and Snowy Mountains Forecast Districts.

It’s all due to a deepening low pressure system sitting around 400km off the Illawarra coast, which is whipping up fierce winds and damaging surf. Some of the recent wind observations are already fairly extreme:

  • A 98 km/h wind gust was recorded at Cabramurra in the Snowy Mountains at 3:59am (interesting fact: Cabramurra, at just under 1500m above sea level, is Australia’s highest town that’s not a ski resort)
  • A 102 km/h wind gust was recorded at Murrurundi in the upper Hunter region at 9:27 pm last night.

Meanwhile at Port Stephens, just north of Newcastle, sea foam was driven onshore by the heavy winds, as shown in this image below.

Further south at Thredbo, some very light flakes of snow are falling above about 1700 metres, in what is the first recorded snowfall on mainland Australia for 2022.

As we write this story just before midday on Friday, temperatures were hovering just below zero at the top station of Thredbo’s Kosciuszko Express Chairlift (elevation 1957 m) having not been above freezing since late on Thursday night.

Meanwhile, there’s one part of the Bureau’s Severe Weather Warning that bears particular relevance to anyone whose suburb, locality or town has suffered heavy rain lately.

It warns that “Saturated soil along areas of the east bring an increased risk of moderately gusty winds toppling trees and powerlines”.

In addition to the gale force winds, a damaging surf warning has also been issued for much of the NSW coast. Weatherzone forecast average wind, wind gusts and wave heights for ports across Australia, for more information, please contact us at apac.sales@dtn.com.
