00:04It's a weather phenomenon you hear a lot about. It doesn't occur a lot. It's called bombogenesis
00:12or a bomb cyclone. Now, they can occur any time of the year, and we've seen them all over the
00:19world. They do tend to occur along the East Coast, and that's what we're going to see over the next
00:2524 hours. All right, what's a bomb cyclone? Very simply, it's a storm where its pressure drops 24
00:31millibars in 24 hours, and remember, as a storm lowers its pressure, what happens? It intensifies.
00:39Wind and precipitation then increase around the storm, and not only do you get heavy precipitation,
00:47you can get damaging winds as well, and as I mentioned, while they can occur any time of the
00:54year, you typically think of them during the winter months here. I want to show you what the
00:58current situation is going on. Water vapor loop. Look at this. All of a sudden, you see everything
01:04moving from northwest to southeast across the Great Lakes. That's because our jet stream is dipping.
01:09You're starting to see the genesis of the storm. See all the white off the North Carolina coast?
01:15This is where the storm is going to start forming. That big dip in the jet stream brings down the
01:23cold
01:23air with the west-northwest flow, and then the storm starts to develop. What aids in storm development
01:30is a difference in temperature. Here comes the cold air, and then you've got the warm gulf stream off
01:38the east coast. That big temperature difference fuels the storm as well.
