Overview

  • The east coast low that reached bomb-cyclone strength on July 2 has weakened and drifted offshore, prompting the Bureau of Meteorology to downgrade severe wind and rain warnings.
  • Warragamba Dam began spilling at around 10:35pm Wednesday, with peak outflows estimated at 60 GL/day and downstream flood warnings in effect for the Hawkesbury-Nepean catchment.
  • Emergency crews have shifted from rescue to recovery after the NSW SES logged over 4,000 call-outs at the storm’s peak, though evacuation orders remain for Wamberal and North Entrance due to coastal erosion risks.
  • Ausgrid and other network operators have restored power to more than 46,000 homes, but roughly 1,650 customers still face outages this morning.
  • Coastal swells up to six metres continue to batter beaches from the Mid North Coast to the Illawarra, sustaining hazardous surf and erosion advisories statewide.
