Severe storms batter Sydney, and much of eastern Australia remains in the firing line

Storms across the Sydney area have dumped large hail.

Storms across the Sydney area have dumped large hail.
The latest round of wild weather has brought large hail and heavy rain as supercell thunderstorms formed over eastern Australia.

Parts of Sydney have already felt the brunt; large hail has fallen in several areas and 24mm hit the rain gauge at Penrith between 3:00pm and 5:00pm AEDT.

The Bureau of Meteorology added a "risk of tornado activity" to its Sydney storm warning just after 3:00pm but it has since been removed.

Severe weather warnings remain current in several states so keep on top of the warnings for your local area.

South-east Queensland and northern New South Wales could well be in for more severe storms tomorrow.

Swells were as high as 6m in yesterday's wild weather.
Wellington's weather was so wild yesterday that a wave-height monitor was washed away across the harbour.

The Lower Hutt suburb of Eastbourne was completely cut off by large swells and debris. Roads on Wellington City's south coast were also closed after rocks from the seawall ended in the path of motorists.

Flights were disrupted and ferries across the Cook Strait cancelled.

By pure coincidence, regional and city councillors were visiting what is the maritime equivalent of an air traffic control centre on Beacon Hill at the time of the storm.

The signal station is staffed 24 hours a day and is the first point of contact for ships arriving to and departing from Wellington Harbour.

A bus carrying 51 people veered off Wangmu Bridge and into the Hutuo River on Monday.
At least 13 people were dead and one missing after a bus ran off a partially submerged bridge and into a swollen river in northern China on Monday morning.

Hebei emergency management authorities said 51 people were on board the bus when it veered off Wangmu Bridge and into the Hutuo River in Pingshan county at around 7am, about 40km (25 miles) from the centre of Shijiazhuang, the provincial capital.

The bridge was partially submerged because the Gangnan Reservoir upstream had discharged water over several days, The Beijing News reported, quoting Qie Yonggang, the official in charge of management and protection of the section of the river.

"The bridge should not be open. There should be security guards watching over the bridge," Qie was quoted as saying.

Hurricane Pamela made landfall on the western coast of Mexico Wednesday as a Category One storm, with life-threatening storm surge and heavy rainfall predicted, the US National Hurricane Center said.

At 1200 GMT, Pamela crossed on to land about 65 kilometers (40 miles) north of the Pacific port of Mazatlan, in the northwestern state of Sinaloa, with sustained winds of 120 kph (75 mph) and was moving at 22 kph (14 mph), according to data from the Miami-based NHC.

The "center of Hurricane Pamela was making landfall on the west-central coast of Mexico near Estacion Dimas," a community of about 3,600 inhabitants, the NHC reported.

Giant waterspout spotted off Greek island of Kythera

The waterspout at Kythera, Greece.
A waterspout formed off the coast of the island of Kythera on Monday. A waterspout is a cylindrical vortex that forms over water and connects to the clouds in the sky.

Waterspouts are typically known as 'sea-tornadoes.' These rotating winds appear to reach down to the sea and take it up as they spiral into the air, but in reality, the water inside the spout originates in the clouds above and snakes its way down to the sea.

Such weather events can be extremely dangerous, especially when they occur over dry land in the form of twisters and tornadoes. Human fatalities from these vortexes are typically between 300-400 each year, according to the World Meteorological Organization.

Summer and winter are clashing, delivering tornadic weather and feet of snow to US

WEATHER
A clash between summer and winter across the central US is causing an autumn outbreak of snow where the air is colder and severe storms, along with tornadoes and flash flooding, where it's warmer.

There's a "big temperature contrast across the country as a battle of the seasons commences," said the Weather Prediction Center.

Cooler-than-average temperatures have infiltrated the West, while above-average temperatures are occupying the East.

Between the two competing air masses is where the extreme weather will battle.

Autumn severe weather is very similar to severe outbreaks we see in early spring -- as colder air clashes with oncoming warming, says CNN meteorologist Chad Myers.

"The shorter fall severe weather season occurs when the warm air of summer is pushed away by the incoming colder air of winter."
