FINAL UPDATE 10am 13/5/18 – ALL SEVERE WEATHER WARNINGS FROM THE SYSTEM HAVE NOW BEEN CANCELLED.
The deep low pressure system is located well off the NSW coast though is it still causing some strong winds and showers to the Central NSW coast. The low is forecast to move South East towards New Zealand during Sunday and Monday with showers being maintained along the NSW coast. This severe weather system has delivered widespread rain to South East Aust (some record breaking rain and flooding in South East Tasmania), damaging and destructive winds from 90 to 135km hr across large parts of South East Aust, large dangerous surf, very cold temperatures, snow to low levels in Victoria, snow on the NSW Central Tablelands with blizzards on the Alps.
We hope everyone has remained safe during this unusual May weather pattern. Our thoughts are with those who suffered damage and losses in South East Tasmania due to severe flooding. Thank you for following Higgins Storm Chasing we hope you have valued our accurate forecasts, warning, updates and coverage of the system. For a full run down of the Super Low please read our detailed blog below.
UPDATE: 6:10PM 12/5/18 The low is now centred around 480km East of Sydney and moving away from the Coast. Scattered showers and light to moderate rain areas are continuing across the NSW South and Central Coastal areas with Merimbula on the NSW South Coast leading all on 27mm since 9am. Strong to damaging winds of 75km/h+ are still lashing the NSW South Coast. Conditions have improved across nearly the entirety of VIC now, however damaging winds and very cold temperatures are still being observed across the Alpine areas.
UPDATE: 1pm 12/5/18 Some big wind gusts have been observed over the Snowy Mountains and Alps in the past 12-18hrs as the Low rips damaging Southerly winds up the NSW Coast and across Eastern VIC.
• Mount Hotham 143km/h (twice) (gusts to over 120km/h for 11hrs straight)

These kinds of winds were no doubt creating blizzard conditions across the peaks of the Snowy Mountains and Victorian Alps overnight.

UPDATE: 8:30am 12/5/18 The centre of the low which has been the cause of all the severe weather over TAS is now located about 250km East of Wollongong on the NSW Illawarra Coast. The system is continuing to move in a general North to North East direction and allowing rain areas to stream along the NSW Coast South of Sydney. Some pockets of moderate falls are occurring and this has lead to isolated falls of 25-40mm being recorded so far. The swell is expected to increase across this morning as the strong winds continue to lash the Coast.
UPDATE: 9pm 11/5/18 Rain areas are easing across the Eastern half of Victoria. These rain areas are expected to continue throughout the night across Eastern VIC where locally heavy falls are possible. The centre of the dominating surface low is situated well East of Bass Strait over the open Tasman Sea waters and is expected to move slowly North leading to an increased swell across the NSW South and Central Coast’s as well as Eastern Coastal parts of VIC during the night and into tomorrow morning. Rain is still falling as snow over Alpine areas such as the Victoria Alps and Snowy Mountains, while flurries cant be ruled out over the highest peaks of the Central Tablelands.
