A severe weather warning for damaging winds, heavy rain and damaging surf has been issued for the Hunter.
The Bureau of Meteorology said the deepening low pressure system was expected to affect the Central Coast and Newcastle from tomorrow evening.
High winds and large waves were due to affect southeastern NSW from tonight.
The Bureau of Meteorology had issued a warning over a low pressure system that is expected to intensify off the Victorian coast today.
The weather phenomenon is the same type that created the destructive storm that grounded bulk carrier the Pasha Bulker at Nobbys Beach on June 8, 2007.
Weatherwatch senior meteorologist Don White said modelling indicated the developing east coast low would move north-east, potentially hitting the Hunter hardest tomorrow.
‘‘It’s probably going to be pretty brief,’’ Mr White said.
‘‘You might have a clearing shower on Wednesday.’’
The bureau forecasts a shower or two for today and rain and increasing winds tomorrow.
Mr White said the exact location of the low’s formation was crucial to assess how hard it would hit particular areas.
‘‘With the Pasha Bulker low it formed virtually on the Newcastle coast,’’ he said.
‘‘Somewhere on the NSW coast could get quite severe weather with this low, but it doesn’t look like it will be as severe as that storm at this point.’’
