Extreme rainfall

Australia's red centre has seen its heaviest rainfall in a decade, with thunderstorms bringing more than 100 millimetres to the central parts of the country.
Yulara Airport, near Uluru, saw 76.4 millimetres of rain in the 24 hours to 9am today, according to Weatherzone, with another 34.4 millimetres falling in just three hours today.
The rain over the last two days is three times more than Uluru's monthly average at this time of the year.
It has caused some roads near the landmark to be closed, but all walking tracks remain open.
"We ask visitors to exercise caution, remain on marked tracks and paths at all times and take care on potentially slippery surfaces," Uluru National Park said in a post on Instagram.
The wet weather is being caused by a low-pressure trough, which is bringing moisture across the centre of Australia.
"The slow-moving nature of this trough, combined with copious atmospheric moisture, is resulting in substantial rainfall in some areas," Weatherzone's Ben Domensino said.
He said the wet weather will spread to other states across the week.
There are flood warnings in Queensland and the Northern Territory, as well as a severe weather warning in place for the northern part of South Australia.
Mapping shows parts of every state will see at least 30 millimetres of rain.
The Bureau of Meteorology's warning said falls of up to 160 millimetres in just one day were possible, leading to the risk of flash flooding.
Towns such as Coober Pedy could be affected, but major centres such as Adelaide will miss the worst of the weather.
