Issued: Sunday, 1 December 2013 at 9am
Severe Tropical cyclone Jonica has slowed but maintains very destructive wind gusts near the core to 220 km/h.
Severe Tropical Cyclone Jonica is now expected to cross the coast on Sunday evening.
Major flooding has developed across the Tweed region with between 100 to 300mm falling in the last hour taking totals to well over 500mm across the region.
At present large waves are combining with the major flooding causing inundation of low lying areas and causing major beach erosion.
Destructive winds with gusts in excess of 125km/h will begin to affect the coast in the next few hours.
More very heavy rain is forecast for at least the next 12 hours worsening the existing flood situation, with the peak storm surge now expected to arrive at the time of high tide on Sunday evening.
Emergency services have been advised that the storm tide may reach 1 to 2 metres above the highest tide of the year in the Gold Coast/Tweed region during Sunday evening, but locally higher when combined with riverine flooding.
Emergency services in Qld and NSW continue to urge residents in these low lying areas to evacuate to higher ground as soon as possible if they have not already done so. Other residents in the path of the cyclone have been advised to stay calm and find a secure place of shelter from the very destructive winds.
The next warning will be issued by 10 am EST Sunday.
