‘Bomb cyclone' to smash state
Residents in NSW are being urged to prepare now as a powerful 'bomb cyclone' bears down on the state. The Bureau of Meteorology's Daniel Hayes said 'bomb cyclone' - or 'bombogenesis' - described a low pressure system that formed 'very quickly', causing pressure to drop significantly within a short period of time. He said the trough was sitting off NSW and would start bringing rainfall and possible thunderstorms to northern parts of the coast on Monday. 'Pretty much from the Mid-North Coast up towards the Northern Rivers,' Mr Hayes said. 'As we see that continue to deepen and strengthen up, the focus for the rainfall will be on the south side of that low pressure system. 'So around more Central Coast areas through (Tuesday) and potentially further south along the coast, as the low pressure system itself shifts further south through Tuesday and into Wednesday.' Sydney could cop more than 200mm of rain in the next week, and parts of the Mid-North Coast could record up to 300mm. NSW SES has now activated all 11,000 of its volunteers in preparation for the wild weather, and are urging members of the community to get ready. NSW SES Acting Assistant Commissioner Allison Flaxman said property damage from destructive winds and flash flooding were significant risks amid the 'dynamic' weather system. 'People should prepare now by tying down any loose items around their homes so they don't become projectiles and damage property in the forecast wind,' she said. 'Be alert today so you're safe tomorrow, by understanding your risk and planning what you will do and where you will go if you are impacted by flash flooding or riverine rises.' The BOM has issued an initial flood warning for several NSW catchments including the Hawkesbury-Nepean, Georges, Cooks, Sydney Coast, and Illawarra Coast. Mr Hayes said flood warnings had been issued to cover 'a fairly wide area' at this stage, given uncertainty of the system's movements. 'We could see some flash flooding as well as river flooding out of this system, depending on just how quickly some of this rainfall falls and how concentrated those falls are in local areas,' he said. 'We do expect to see further warnings issued for NSW today, basically for the developing situation. 'Once the system starts to have some significant impacts, there could be additional, more localised warnings issued ... so certainly people (should) keep an eye out for warnings and track the situation.' Inland areas of NSW and Victoria were tipped to see frost and fog on Monday morning, with frost warnings issued for the Northern Country, North East, and East Gippsland forecast districts. Melbourne is expected to hit a top of 14C with partly cloudy conditions and the chance of a shower. Those in Brisbane are likely in for a rainy day with a top of 17C, while Adelaide residents can expect a mostly sunny day with a maximum of 15C. Temperatures are tipped to reach 13C in Canberra after a freezing start, with a similarly chilly 12C forecast for Hobart. Monday is likely to be warm and sunny for those in Darwin with a high of 31C. Perth is expected to reach 23C with a mostly sunny morning before a high chance of showers in the afternoon and evening.

Sydney weather: 'Bomb cyclone' set to strike: What you need to know
Millions of Australians are being warned to brace for heavy rain, damaging winds, and dangerous surf conditions as a bomb cyclone threatens the country's east coast. A powerful low-pressure system is forecast to intensify rapidly within 24 hours as it develops off the coast of NSW on Monday. Starting Tuesday, up to 200mm of rain is expected to lash areas between Newcastle, Sydney, and the Illawarra over just 48 hours. The growing system is being referred to as a potential 'bomb cyclone,' known for its explosive development from calm to chaos in a short time. 'We could see the equivalent of a category one, possibly category two [cyclone], with these wind gusts,' Today show weather presenter Gary Youngberry said. 'It will be a very nasty weather system... the worst of it from early Tuesday morning, right into Thursday and it'll impact the entire NSW coast.' Bureau of Meteorology meteorologist Anges Hines explained that the powerful weather system would drench and batter parts of NSW and Victoria from Monday, with up to 200mm of rain expected. 'On Monday, we'll see the wind picking up and probably a few showers through the evening. But Tuesday's the day when it is really going to deteriorate, and it's going to be very wet and very windy, so the rain will likely last through much of the day. 'We will see the winds absolutely howling up that NSW coast. 'We could certainly see those gusts upwards of 80, 90, even 100 kilometres per hour around parts of the Sydney Metro area on Tuesday – that's definitely enough to cause a bit of damage, bring down some trees. We could be talking about power outages as well.' He explained that the affected area stretches from the far south of the Mid North Coast, through the Eastern Hunter, Sydney, the Illawarra, and the South Coast, continuing all the way into Gippsland. 'Then on about Thursday, between Thursday and Friday, it pulls out of the Tasman, getting quite far away from the country and also weakening at the same time. '100 to 200mm of rain possible through these areas over 48 hours, and I expect some locations will pick up even more than that.' Mr Hines said the heavy rainfall would bring the risk of riverine flooding, flash flooding, and dangerous driving conditions throughout the state. He told Daily Mail Australia that the wet change would replace a fairly stubborn high-pressure system, which had brought a stretch of clear weather to the state. '(The low-pressure system) will develop near the coast in the north of (NSW), somewhere near the Northern Rivers, but it really intensifies in the southwest, so closer to the Hunter, closer to Sydney where it becomes a powerful weather system on Tuesday,' he said. 'Then on about Thursday, between Thursday and Friday, it pulls out of the Tasman, getting quite far away from the country and also weakening at the same time. 'For anyone near the water there's going to be powerful waves and potential coastal erosion, it's a fairly notable outbreak of weather,' Mr Hines said. 'It could be over 100mm of rain particularly over the eastern parts of Sydney ... but basically wherever you are wet day Tuesday, wet day Wednesday.' The SES has warned residents along the east coast to prepare for the system. 'People should prepare now by tying down any loose items around their homes so they don't become projectiles and damage property in the forecast wind,' SES Acting Assistant Commissioner Allison Flaxman said.
