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.
Residents should prepare for the worst of the storm late Sunday night, when snowfall rates could exceed 2 inches per hour. The weather service believes the heaviest snow will come down from 7 p.m. Sunday through about 12 p.m. Monday. The snow is expected to develop Sunday morning and afternoon, possibly mixing with rain at the onset before tapering off late Monday morning into Monday afternoon.
Wind chill is a measure of how quickly bodies lose heat when you combine low temperatures with high winds. And wind chill conditions can be dangerous. "The stronger the winds [and] the colder it is, the more likely you are to develop frostbite in a short amount of time or hypothermia," says Jessica Lee of the National Weather Service's Weather Prediction Center.
A deep area of low pressure crossing the south of the UK will bring a 'multi-hazard' event through Thursday and into Friday. An Amber warning for wind has been issued for the west of Cornwall and the Isles of Scilly where potentially exceptionally strong winds could cause significant impacts. An Amber warning for snow has been issued for most of Wales, the Midlands and southern parts of northern England. Numerous Yellow warnings for wind, snow and rain have also been issued across different regions of England and Wales.
A record-breaking snowfall event unfolded in far eastern Russia last week when the town of Petropavlovsk-Kamchatsky, located on the Kamchatka peninsula's east coast, received more than 1.8 metres (6 feet) of lying snow in places. Strong winds accompanying the snowfall caused extreme drifting of more than 3 metres against buildings and cars. Two key ingredients combined to cause such an extreme snowfall event. Strong Pacific low pressures dragged moist air from the tropics northwards, which clashed with cold Arctic air already over the region. Conveyor belts of tropical air are called atmospheric rivers and often bring heavy rainfall to places such as California.
