The storm intensified rapidly off the US east coast.
The US was hit by a 'bomb cyclone' last week, bringing icy cold and driving snow. These storms develop very rapidly, forming outside the tropics, typically on continental east coasts in winter.

Geostorm is the newest addition to the Hollywood climate doom canon. It is terrible, which is why you should think about this genre but under no circumstances actually watch this movie.

Saturated media coverage of hurricanes like Harvey and Irma can make it seem like disasters happen all the time. Is the frequency of billion-dollar disasters really rising?
When this is home, bad weather can make a bad situation much worse.
Extreme weather is hard enough for those with a home. But imagine losing everything you own in a storm - that's the experience of many homeless people forced to live out in the open during wild weather.
Houston’s Interstate Highway 45 was totally submerged in the deluge.
The unpredictability of hurricanes makes it hard to say for sure whether climate change is making them worse. But we do know that sea-level rise and increased evaporation will worsen the impacts.
A taste of things to come? Storm damage on Sydney’s northern beaches in 2016.
The ocean warming that might increase the threat of a catastrophic storm could also create the conditions for a natural defensive barrier.
All schools were closed throughout south-east Queensland due to severe rain.
Bad weather conditions often force schools to make unplanned closures.

Most people in Australia's southeast are familiar with the stormy weather known as East Coast Lows. But they might not realise how much scientific progress has been made in understanding them.
Was the prime minister right about storms and global warming?
Was Malcolm Turnbull right to say that larger and more frequent storms are one of the predicted consequences of climate change – but that you can't attribute any particular storm to global warming?
Most people die in floods when they choose to go into the water.

Eastern Australia's massive storms will likely become rarer in a warmer world, but probably more intense.
Climate change isn't the only thing making sea levels higher and cyclones more intense.
