Severe Weather Warning
for DAMAGING WINDS and HEAVY RAINFALL
For people in Mid North Coast and parts of Hunter and Northern Tablelands Forecast Districts.
Issued at 5:00 am Friday, 19 March 2021.
HEAVY RAIN, POSSIBLY LIFE THREATENING, AND DAMAGING WINDS FOR THE MID NORTH COAST, THEN EXTENDING SOUTH.
A coastal trough continues to intensify off the northern New South Wales coast. An embedded Coastal Low is expected to form within the trough today, and this low is forecast to slowly track down the north coast later later today
HEAVY RAINFALL, leading to FLASH FLOODING, is expected about parts of the exposed Hunter coastline as the trough deepens. Increased rainfall rates about areas of the Mid North Coast are likely to continue to develop today as a low is forecast to form off the Mid North Coast, shifting south as the low moves down the north coast.
INTENSE RAINFALL which may lead to dangerous and life-threatening flash flooding may develop in areas of the Mid North Coast and northern Hunter districts as continued rainfall impacts the region. Roads are likely to be cut off by water, and there will be an increased risk of landslips over this period.
DAMAGING WINDS, averaging 60 to 70 km/h with peak gusts in excess of 90 km/h are likely to develop today along the coastal fringe as the low develops in the Mid North Coast, with the area of impact moving south by the evening.
The exact positioning and movement of the Coastal Low will impact the areas of strongest winds and highest rainfall, and updates to the warning will be issued as this system develops.
As catchments are relatively wet in the Mid North Coast, RIVERINE FLOODING is also possible. A Flood Watch has been issued, covering the Mid North Coast, Hunter and parts of Sydney. See the latest at http://www.bom.gov.au/nsw/warnings/flood/floodwatch1.shtml.ed.
Locations which may be affected include Coffs Harbour, Port Macquarie, Taree, Newcastle, Gosford and Maitland.
Severe weather is no longer occurring in the Northern Rivers district and the warning for this district is CANCELLED.

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.
* Trees that have been damaged by fire are likely to be more unstable and more likely to fall.
* Report fallen power lines to either Ausgrid (131 388), Endeavour Energy (131 003), Essential Energy (132 080) or Evoenergy (131 093) 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.
* Be aware that run-off from rainfall in fire affected areas may behave differently and be more rapid. It may also contain debris such as ash, soil, trees and rocks.
* After bushfires, heavy rain and the loss of foliage can make the ground soft and heavy, leading to a greater chance of landslides.
* Stay vigilant and monitor conditions. Note that the landscape may have changed following bushfires.
* For emergency help in floods and storms, ring your local SES Unit on 132 500.
The next Severe Weather Warning will be issued by 11:00 am AEDT Friday.
