An unseasonable low pressure system brought wild weather to the South West yesterday, with strong winds and periods of heavy rain lashing Bunbury and its surrounds.
The effects were apparent along the coast where a combination of higher than normal tides and rough seas caused three yachts at Koombana Bay Sailing Club to slip its moorings and run aground, where it was quickly submerged.
Bureau of Meteorology climate and weather information officer John Relf said cold fronts were a common occurrence during the winter months but a low pressure system this far into spring was rare.
“A front of this calibre is extremely unseasonable and can be dangerous,” Mr Relf said.
“Aside from the strong winds and rain there’s an increased bush fire risk from lightning strikes because of all the brush that has dried throughout spring.”
The storm was expected to pass last night and some lighter residual wind and rain is expected to clear up by tomorrow night.
The Bureau of Meteorology was expecting between 15 and 25mm of rain yesterday which would bring total rainfall for November to about 50mm, almost double the month’s average.
Mr Relf said the Bureau was expecting a wetter than usual summer but did not anticipate another low pressure system in summer.
The West Australian State Emergency Services did not receive any call outs yesterday morning but urged residents to remain vigilant during any kind of unusual weather event.
