The study highlights how rapid Arctic warming increases the frequency of extreme weather events, particularly concurrent heatwaves across Europe and eastern Asia.

We created Earth in Action to provide a lens into what's happening on our planet, as it happens. Whether it's something typical, like the current air temperature, or an extreme event like a major dust storm, we wanted to provide an opportunity for people to see them.

"This is going to help fill that gap in minutes to hours lead time that's vital to know where the heaviest rain is going to hit," Ralph said. "And when and what communities are going to be affected so people in the preparedness community and water resource management community can take action to help protect people's lives and property."

The winter we had this year, it was colder than last year, so the snow held more water. That water ends up in our waterways. Mississauga is home to many bodies of water, including rivers, lakes, stormwater ponds and Lake Ontario, which increases flooding especially this time of year.

In late January, Toronto was hit with what many experts said was the heaviest single day of snowfall in the city's history. In some spots, nearly 23in fell, driven in part by a collision of weather systems. The city had already removed 264,000 tonnes of snow from 1,100 km (680 miles) of roads, sidewalks and bike lanes by mid-February.

The temperature at the Toronto airport reached a high of 17.6 C on Saturday, breaking an old record for March 7 of 17.2 C that was set in 1860. It says a weather station in the St. Catharines area recorded a high temperature on Saturday of 20.3 degrees, while further north in Wiarton, more than 40 millimetres of rain was recorded.

When I spoke with emergency management officials last year, they all mentioned the same frustrating scenario. People ignore storm warnings until the precipitation starts falling, then suddenly everyone rushes out at once. The roads become congested with anxious drivers, accidents spike, and stores run out of essentials just when people need them most. But here's what really gets meteorologists worked up about this pattern. Modern weather forecasting has become incredibly accurate, especially for major winter storms.

One commuter based in Islington, North London, wrote on social media: 397 a month council tax and they can't even put a bit of grit in the roads. Death trap out there today. Simon O' Farrell from Richmond added: Disgraceful lack of gritting around Whitton. Roads and pavements icy. People sliding around all over the place. It's winter, it's icy. We pay a fortune for council tax. Get on with it! Atrocious ice in SW London. Main high street almost impossible to walk on. Useless councils, said another. The Councils in London are not even bothered about gritting the roads after a snowy morning. All the pathways and main roads are filled with ice all day. That's a disaster waiting to happen, another added.

The reason we can gracefully glide on an ice-skating rink or clumsily slip on an icy sidewalk is that the surface of ice is coated by a thin watery layer. Scientists generally agree that this lubricating, liquidlike layer is what makes ice slippery. They disagree, though, about why the layer forms. Three main theories about the phenomenon have been debated over the past two centuries. Last year, researchers in Germany put forward a fourth hypothesis that they say solves the puzzle.

"It will prove cold with some frost and ice in places on Friday morning, especially in the west and north," she said. "Munster and south Leinster will see cloud, but that will clear to leave dry and sunny conditions with a few isolated showers in the north and highest temperatures of 3C to 7C," she said. Friday night will prove mainly dry but very cold and frosty with some icy patches.

Toronto is under a yellow snowfall warning with 10 centimetres of snow expected to affect the morning and evening commute on Wednesday. An Alberta clipper, a low pressure system, is forecast to bring the snow starting Wednesday morning and easing in the afternoon, Environment Canada said in the warning issued late Tuesday afternoon. Visibility could be poor at times if the snow is heavy or blowing, the agency says.

We've been in this position before, and we've caught up in the past.
