00:00Two years ago, Hurricane Helene moved north from the Gulf and produced catastrophic flooding in the mountains of western North
00:06Carolina.
00:06Over 30 inches of rain fell in Yancey County and it became the deadliest hurricane on the mainland U.S.
00:12since Katrina.
00:13Drenching rain that preceded Helene saturated the soil before the storm even arrived and strong upslope flow persisted for days
00:20leading to extreme rainfall.
00:22While Isaias will bring a flood threat to western North Carolina, it will not match what we saw with Hurricane
00:28Helene's intensity.
00:29And here's why. Number one, we've been dry in recent days. Take a look at this. You can see over
00:34the past couple of days, no rain in North Carolina.
00:37Isaias will be moving on a slightly different trajectory than Helene did. A little farther west, moving more swiftly to
00:43the north.
00:44Here's the big thing that will mitigate most of the worst of the trouble. The upper level steering flow will
00:48keep this storm moving along.
00:50Instead of it just fading and fizzling and dying southwest of the mountains of North Carolina, it will keep moving
00:55through the region.
00:56It will be very wet. We're expecting four to eight inches of rain that will lead to some flooding.
01:01But the worst of the impacts are not going to resemble what we saw two years ago.
