World weather news, September 2016

20th-21st
Torrential rain dumped over the Norfolk, Virginia (USA), area Tuesday into Wednesday morning and left streets looking like rivers. Over 13.5 inches of rain fell in Kempsville, Virginia, just south of Norfolk in 72 hours, according to CoCoRAHs. Steady rain fell over southern Virginia as lingering impacts from tropical storm Julia brought moist, tropical air into the area. Several roads were closed in the area and some schools were cancelled due to the intense flooding. The extensive flooding also prompted some schools across the region to be either delayed or closed.

Floodwaters predicted at two rural New South Wales towns (Australia) will peak later and more gently than previously thought, but evacuation orders remain in place. While floods were expected to peak at Forbes and Condobolin during the day on Sunday, the Bureau of Meteorology were now predicting the peak around midnight or early Monday morning. Lachlan river, near Forbes, was expected to reach almost 10.7m after the area received an extra 17mm overnight but will peak gently, the BoM senior hydrologist Hugh Bruist said on Sunday. About 1,000 people in Forbes were ordered to evacuate on Saturday while residents at Condobolin remain on standby pending possible further flooding. While flooding in Forbes has surpassed the 1990 floods, in which the Lachlan river reached 10.65m, the worst is now being predicted to hit next week. Farmers in flood-affected regions were nervously waiting to see how much damage has been done to crops once the waters recede, a NSW Farmers spokesman said. To date more than 2,000 sheep and more than 1,000 head of cattle have been moved to higher ground.

South Australia was weathering a statewide blackout on Wednesday night after one of the most extreme weather systems in decades cut power to the entire state. Power went out across the state at about 3.45pm on Wednesday afternoon in the midst of drenching rains, lightning and thunder. By late on Wednesday, power had been restored to much of the Adelaide metropolitan area and only the northern parts of the state and the Eyre Peninsula were expected to be without services into Thursday. An incident involving infrastructure near Port Augusta at 3.48pm on Wednesday prompted the failure of the entire SA network, the South Australian premier, Jay Weatherill, said. The blackout came as strong winds and heavy rain lashed parts of SA with the Bureau of Meteorology warning super cell thunderstorms were possible across the central and mid-north districts. The bureau issued a severe thunderstorm warning for an area stretching from the Riverland to Marree. It said super cells within those storms could produce wind gusts up to 140 km/h along with heavy rain that could cause flash flooding. By late afternoon the State Emergency Service had responded to more than 330 calls for help, most because of fallen trees or rising water.

More than 600 people were injured and five were killed after once-Typhoon Megi roared across Taiwan and eastern China. Megi made landfall in central Fujian, near the city of Putian, early Wednesday morning local time. The system has since weakened to a tropical rainstorm. Despite weakening, Megi will continue to pose risks to residents in eastern China by unleashing flooding downpours through late week. While the risk of damaging winds has diminished, flooding rain will remain a concern. Mudslides can be triggered in the higher terrain.

South Australia has copped another belting with a destructive storm lashing the state just 24 hours after super cell thunderstorms knocked out the state's entire power network. The intense low pressure system raged across Adelaide and parts of South Australia late on Thursday. The storm packed winds of up to 140 km/h, among the strongest the city has experienced, prompting an unprecedented warning from police for workers to head home early and stay home amid concerns emergency services might not be able to cope. The winds brought down trees across a wide area, causing major damage, and ripped some mid-north buildings apart. Heavy rain caused widespread flooding, from the Patawalonga River in Adelaide, through to the Barossa and Clare valleys, which copped 54mm of rain. In Clare, a caravan park was under threat and in the Barossa, a dam burst, prompting an emergency flood warning for the town of Greenock. Storm surges and huge waves also inundated some communities along the Spencer and St Vincent gulf coasts with the worst centres affected including Port Pirie, Port Broughton and Moonta.
