00:00Homegrown development occurs right near the United States, whether that be off the southeast coast, in the Gulf, or in the western Caribbean.
00:07That's why we call it homegrown tropical development.
00:10Some hurricanes that strike the U.S. begin thousands of miles away near Africa, crossing the Atlantic before reaching land.
00:16But at certain times in the season, tropical threats can form much closer to home.
00:21We're talking June and July, and at the very end of the tropical season, so think the end of October and into November.
00:27These systems can develop quickly off the U.S. coast.
00:31Homegrown development originates from either an old cold front that's sinking south across the southeastern United States,
00:37and then it might stall off the southeast coast or into the Gulf.
00:40You get a little bit of spin on the end of the cold front, and then you can get tropical development that way.
00:45The western Caribbean is another area to watch when the jet stream dips low.
00:49That helps to induce some spin in the western Caribbean, really helps to get what we call that central American gyre going.
00:55So that's essentially an area of thunderstorms and rotation that occurs over Central America.
01:01Unlike tropical waves from Africa, homegrown systems offer far less lead time.
01:06Tropical waves that originate from Africa typically take about 12 to 14 days to reach the United States.
01:13That's a luxury that we just don't have with this homegrown development, which can take one to four days.
01:20That's why it's important to be prepared and stay alert.
01:23These tropical systems, they have to be watched even more carefully a lot of times because they're so close to the United States and can almost sneak up on people.
01:32So that's why it's so important to look and follow the AccuWeather forecast very, very carefully, especially when it comes to these homegrown development systems.
