AccuWeather

The interaction between the jet stream over North America and tropical waters during the summer can make for a stormy combination, resulting in tropical development near the U.S. East Coast.

00:00 Some hurricanes that hit the US spawn thousands of miles away near the west coast of Africa.

00:06 They then travel across the Atlantic where they finally reach the east coast.

00:11 But during the mid-summer, a tropical threat can form much closer to home.

00:16 You see this kind of development during the month of June and generally in early July as well.

00:21 It's what we call homegrown development in the tropics.

00:24 Homegrown meaning that tropical development is close to the United States.

00:29 The two main areas for this type of development are the Gulf of Mexico and off the southeast coast of the US.

00:35 The key to these storms is upper atmospheric energy within the jet stream

00:39 that dips south over the toasty warm waters near the United States coast,

00:43 like a spark to a pile of gunpowder.

00:46 The resulting storms can explode with torrential rain, storm surge, and fierce winds.

00:51 With enough time, these homegrown storms can strengthen to tropical storms and sometimes even hurricanes.
