Bomb Cyclone Causes Severe Weather, Power Outages
A very strong winter storm called a 'bomb cyclone' is bringing lots of snow, ice, rain, and strong winds to many parts of the US, especially the Upper Midwest and Great Lakes.
This storm has caused over 350,000 people to lose power, with a third of them in Michigan.
The National Weather Service says that heavy snow, blizzards, and freezing rain will make travel and outdoor activities very difficult.
The storm is moving eastwards and will intensify due to clashing cold and warm air masses.
Minnesota's governor has called in the National Guard to help with emergency operations.
People in these areas should be careful and follow weather updates to stay safe.
