East coast low to form off North Coast
11AM: AN East Coast Low is expected to form off the North Coast delivering rainfall up to 100mm from tonight.
The Bureau of Meteorology issued a severe weather warning for the North Coast on Tuesday at 11am.
"A cold front will move through northeastern New South Wales Tuesday night and as it moves offshore a low is expected to develop off the far north coast during Wednesday morning," the bureau said.
It advised heavy rain, may lead to flash flooding in southern parts of the Mid North Coast tomorrow morning and extend to northern parts by Wednesday afternoon.
Damaging winds averaging 60 to 70kmh are expected with peak gusts in excess of 90kmh along the coast.
Abnormally high tides will also occur seeing sea water inundate low lying areas on Wednesday night.
Heavy surf is expected to lead to coastal erosion particularly on south facing beaches.
Locations, which may be affected include Coffs Harbour, Port Macquarie, Taree, Woolgoolga, Sawtell and Dorrigo, the weather bureau advised.
The State Emergency Service advises that people should:
* Move vehicles under cover or away from trees.
* Secure or put away loose items around your house, yard and balcony.
* Keep at least 8 metres away from fallen power lines or objects that may be energised, such as fences.
* Report fallen power lines to either Ausgrid on 131 388, or Endeavour Energy on 131 003 or Essential Energy on 132 080, as shown on your power bill.
* Don't drive, ride or walk through flood water.
* Keep clear of creeks and storm drains.
* If you are trapped by flash flooding, seek refuge in the highest available place and ring 000 if you need rescue.
* For emergency help in floods and storms, ring your local SES Unit on 132 500.
The next warning is due to be issued by 6:05pm.
Warnings are also available through TV and Radio broadcasts, the Bureau's website at bom.gov.au or call 1300 659 218. The Bureau and State Emergency Service would appreciate warnings being broadcast regularly.
TUESDAY, 8AM: METEOROLOGISTS are today monitoring a weather system that is expected to develop into an East Coast Low near Coffs Harbour.
Initial forecasts from the Bureau of Meteorology are that the system could deliver falls of over 100mm over the next 36-hours.
The bureau says the East Coast Low is expected to form off the coastline tonight between Byron Bay and Taree.
"We are still monitoring the conditions over the next 24 hours to see what conditions we are expecting," the bureau said.
Heavy seas and winds reaching 30-50kmh are expected along the coast today.
"Some areas can expect as much as 150mm of rain, damaging winds reaching 90km/h and powerful surf, Weatherzone's senior meteorologist Brett Dutschke said.
As rain clouds build over the Coffs Coast today, weatherzone has forecast a 90% chance of 40-80mm in Coffs Harbour on Wednesday.
Thursday will see a 90% chance of 5-10mm of rain in Coffs Harbour with southerly winds reaching 30kmh.
The likelihood of torrential rain and flash flooding will be monitored by State Emergency Service crews.
Higgins Storm Chasing says the east coast low will combine with a surface trough and upper level support to generate the heavy rain.
"These kinds of falls have the potential to lead to flash flooding with roads cut, as well as creek and river rises that could see minor to moderate flood warnings issued," Higgins Storm Chasing said.
