A blizzard warning is in effect for Michigan’s Upper Peninsula as a bomb cyclone — a rapidly intensifying winter storm — crosses the Great Lakes.

Snow, ice, rain and strong winds swept across much of the country as meteorologists warned that the storm could rapidly intensify.

An intense storm system may "bomb out" over the Great Lakes today into Monday! Check out what this means and our impacts from Meteorologist Nick Dunn.

Travel is probably going to be not just hazardous, but almost impossible across a large area of Michigan when this storm hits Sunday night and into Monday.

While hurricanes are fueled by warm ocean waters, bomb cyclones are "cold-core" systems. They are typically triggered when a cold air mass from the north collides with a warm, moist air mass, creating a sharp temperature gradient that provides the energy for the storm to deepen quickly.

A second storm in just three days' time will bring another round of wintry weather across a large swath of the central and eastern US beginning Sunday, with the added risk for strong winds to interrupt travel.
