WILD WEATHER: Brace for strong winds and destructive waves
THE Northern Rivers can expect a lashing from wind and waves - but not too much rain - late Friday and early Saturday as a massive low pressure system moving over southeastern Australia makes its presence felt here.
While inland areas from central Victoria to the Darling Downs in Queensland are expected to get up to 100mm of rain to cap off winter, less than 10mm is forecast for the Northern Rivers on Saturday.
But strong winds and swell will have a significant impact along the coast.
The action will start on Friday afternoon as a low pressure trough with an accompanying cold front deepens before moving over the Tasman Sea during Saturday.
Winds are expected to increase from the northerly direction to about 40km/h on Friday evening.
A swell from an unusual north-northeast direction (usually associated with cyclone-type swells in summer) will pick up to about a metre at north-east exposed beaches and bays.
The trend will continue upwards overnight into Saturday, with peak winds early Saturday morning hitting up to 60km/h.
The accompanying swell will peak at just under 2m on Saturday morning, again from the northerly direction.
The system will be short-lived however, moving off quickly to the southeast, and both wind and swell will taper off during Saturday afternoon.
In the wake of the trough another high pressure system is expected to move over southeastern Australia on Sunday, setting up fine weather into next week.
What the Bureau says
The Bureau of Meterology are expected to issue a strong wind warning for the coastal areas of the Northern Rivers for both Friday and Saturday.
Duty forecaster Ashleigh Lange said the Northern Rivers had medium chance of showers of between 0.5-3mm on Friday.
On Saturday, there was a high chance of rain, with expected totals between 4-10mm.
