Bunker down for more wild weather: bom
HOWLING winds and big seas will continue to pound the Tweed Coast until the end of the week, according to a Bureau of Meteorology forecaster.
Forecaster Michelle Berry said the upper-level trough containing a number of offshore surface-level lows that sent pummelling rain and gale-force winds to the coast, would move offshore and a ridge would develop behind it.
“As the upper low moves offshore, the ridge develops behind the trough, pushing the trough north through the Coral Sea and developing strong potentially gale-force south, south-easterly winds,” Miss Berry said yesterday.
She said the weather would ease late today and tomorrow, but there was still potential for rain squalls and gale-force winds.
Ms Berry said the trough over Queensland formed at the “right time” because there was plenty of moisture in the air to feed into the trough and create a system.
“An upper low led to the development of this surface trough and associated low pressure system, and as that upper low moves slowly offshore during Thursday and Friday it has pushed a surface trough and embedded low pressure centres south over the New South Wales border, that is why the heaviest falls and gale-force winds have contracted into NSW now,” Miss Berry said.
But she said this sort of weather was common this time of year.
And while the conditions might have felt cyclonic over the past few days, the current weather system is technically far different to a cyclone.
Cyclones are a warm-cored, low-pressure system, while the current weather over northern New South is a cold-cored system.
Heavy rainfall is likely on the coast and ranges north of Kempsey today. It will ease on the weekend, turning into scattered showers.
