COASTAL LOW BRINGS DAMAGING WINDS, SURF, AND POSSIBLE HEAVY FALLS, TO CENTRAL AND SOUTHERN PARTS OF COAST
A low pressure system currently just off the Illawarra coast is maturing and slow moving, while bringing damaging wind gusts and wind-driven large sea waves along the southern coast. The winds and waves may extend north to Sydney and possibly up to the Central Coast this afternoon, before easing later this evening or early Tuesday as the low gradually weakens.
DAMAGING WINDS, averaging 60 to 70 km/h with peak gusts in excess of 90 km/h are expected along the coastal parts of the Illawarra and the South Coast districts, and are likely to extend to the Sydney coast and possibly up to the Central Coast this afternoon. Damaging wind gusts over the Southern Highlands and the coastal ranges of South Coast are also possible. Winds should gradually ease later this evening or early tomorrow as the low gradually weakens.
VERY HEAVY SURF which may lead to localised damage and coastal erosion with wind-driven large sea waves is also possible today, especially in the south-facing surf zones.
Beach conditions in these areas could be dangerous and people should stay well away from the surf and surf exposed areas.
In addition, Hazardous Surf Warning is current, covering the coastal areas from the South Coast to Hunter Coast. See http://www.bom.gov.au/nsw/warnings/hazardoussurf.shtml
HEAVY RAINFALL, which may lead to localised flash flooding, is also possible over the Illawarra and the South Coast districts this morning. Rain rate should ease from this afternoon, although steady rainfall will still continue.
Locations which may be affected include Sydney, Wollongong, Nowra, Bowral, Batemans Bay and Eden.
Bellambi AWS recorded 91 km/h wind gust at 12:58 am Monday.
Kiama AWS recorded 91 km/h wind gust at 01:41 am Monday.
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.
