The Informer: More evacuations expected in NSW amid flooding

A house was seen floating down the Manning River after a weekend of pouring rain brought widespread flash flooding across NSW coastal areas.

But spare a thought for the homeowners, a couple who lived near Mondrook, near Taree, who were due to be married on Saturday.

Now the pair are homeless and have lost their pets in the flood, which ripped their cottage from its foundations and is higher than Taree's 1978 and 2011 flood levels.

A fundraiser to support the couple had already raised more than $20,000 to support the engaged couple by Saturday afternoon.

The heavy rain is forecast to continue, with a severe weather warning still in place. Some areas could see a metre of rain fall in a week.

"A low pressure trough lying along the New South Wales coast is generating widespread and persistent rain in many eastern districts, along with windy conditions. This trough, in conjunction with a strong high to the south, is also bringing windy weather to higher parts of the southern ranges," the Bureau of Meteorology said in a statement.

"Most parts of the warning area will see the heaviest rain during the next 24 hours, however some places may experience periods of heavy rain through to Monday or Tuesday.

"The focus of heavy rain in the next 6-8 hours will be the Sydney Metropolitan, eastern Central Tablelands, and Illawarra districts. Later this evening, or early Sunday, there is a high likelihood of heavy rain re-developing in the Mid North Coast and southern parts of the Northern Rivers districts."

Nine official gauges in NSW recorded more than 200 millimetres of rain to 9am on Saturday, with Delward notching up 405.5 millimetres.

NSW Premier Gladys Berejiklian says the state is in the grip of a prolonged, extreme weather event and threatened communities won't be out of the woods until the end of next week.

Ms Berejiklian has put already flooded and vulnerable communities on an emergency footing, and says more evacuations will certainly be ordered.

"Make sure if you are asked to evacuate you do so immediately. The window for evacuation is not a big one depending on where you live. Some communities already have been advised to stock up and stay home," the premier said on Saturday.

Residents in the Warragamba Dam catchment are on high alert and may have to evacuate as the primary reservoir of water supply for Sydney overflows.

The heritage-listed Warragamba Dam, located about 70km from central Sydney, started spilling mid-afternoon on Saturday.

And finally, from floods to volcanoes.

A volcanic eruption has begun in southwestern Iceland near the capital Reykjavik following thousands of small earthquakes in the area in recent weeks, the country's meteorological office says.

The eruption occurred near Fagradalsfjall, a mountain on the Reykjanes Peninsula, located around 30km southwest of the capital.

Unlike the floods, though, the eruption posed no immediate danger.
