Hurricane Dorian is threatening to bear down on Florida by Monday, prompting residents there to start stocking up on bottled water, gas and other supplies.But the Category 1 hurricane's precise path is hard to predict.Dorian veered towards the Virgin Islands, drenching them with heavy rain and whipping winds, but then largely missed Puerto Rico.Ken Graham is the director of the National Hurricane Center in Miami, and he joins us now for an update.Ken Graham, welcome back to the "NewsHour." First of all, tell us what you know right now about Dorian.Every indication is continuing to get stronger.We're looking at this structure very closely, getting aircraft out there, studying this 24 hours a day.And getting stronger is exactly what we're forecasting, continuing to get stronger with time,just a lot of warm water, not a lot of shear, and then not a lot of interaction with terrain as well.So it's gonna keep getting stronger. And we're forecasting to become a major hurricane,even a Category 4-strength,130 miles an hour, as we approach the Florida coast, so a big event, a lot of uncertainty in the forecast.That center could be anywhere in that cone. And, Ken, you say a lot of uncertainty.What is gonna determine the exact path and the strength of this storm? Yes, so many factors going on here.In this case, we have, this ridge of high pressure.It's out here. It almost acts like a bubble.So, when the storm moves forward, it hits that bubble. So the stronger that high pressure is, then we're going to have a quicker turn.
飓风多里安预计周一就会逼近佛罗里达州，迫使那里的居民现在已经开始储备瓶装水、天然气和其他应急物资了。但是这股一级飓风的确切运动路径很难预测。多里安此前已经转向维尔京群岛，受其影响，那里大雨滂沱，狂风呼啸，但其却出人意料的避开了波多黎各。现在让我们与迈阿密国家飓风中心主任肯?格雷厄姆一起了解一下多里安的最新情况。肯，欢迎你回来“新闻一小时”节目。首先，请跟我们分享一下你对多里安的了解。不断有迹象表明飓风即将来临。我们近距离的研究了这个飓风结构，让飞机飞到那里，每天24小时对其进行研究。我们早已预料到飓风趋势会变强，并且预计随着时间的推移这种趋势会变得更强，只是海水温度升高，水位上涨，切变力没有增加多少，地形地势也没对其产生多大阻碍。所以它会越来越强。我们预测它将成为一场大飓风，甚至是4级飓风，时速可达130英里，当其逼近佛罗里达海岸时，这是一个大事件，但是预测中还存在很多不确定性。中心可以在那的任何位置。肯，你说有很多不确定性。那么什么将最终决定这场风暴的确切运动路径和强度? 是的，这中间有很多影响因素。在多里安这场飓风中有高压脊。它在这里，几乎就像一个泡沫。所以，当风暴向前移动时，他就推动了这一泡沫向前移动。所以压强越大，转弯的速度就越快。
