00:00When you compare to what happened yesterday or what Aaron looked like yesterday, it's a totally, totally different hurricane right now.
00:09Yeah, yesterday I think the storm underwent or started to undergo another eye wall replacement cycle.
00:15An eye wall replacement cycle, let's talk about exactly what that is and what it has meant for Hurricane Aaron specifically.
00:22So in any hurricane, you have the eye of the storm system and right on the outside is the eye wall.
00:26That's what we're going to be talking about.
00:28Now, in these eye wall replacement cycles, you have the inner eye wall.
00:31It ends up getting as strong as it can be in the current storm system.
00:35Then you see an outer eye wall develop.
00:37Eventually, it takes over and becomes the dominant eye wall, hence eye wall replacement cycle.
00:43It can also be compared to a snake shedding its skin.
00:46That's probably an easier way to think about it.
00:48Now, what does this mean for the storm system?
00:50There's a couple things that happen as this process is taking place.
00:54For Aaron specifically, we've seen fluctuations in intensity of the storm.
00:58We've seen the size of the actual eye of the hurricane change.
01:02We've also seen the wind field expand.
01:04Let's dive into those a little bit more.
01:06So first, the intensity changing.
01:08We've gone from a category 5 to a category 3, a category 4, and then ultimately a category 2 for a lot of the day Tuesday.
01:17A lot of this was happening, the storm going down in categories as the eye wall replacement cycle was ongoing, then reintensifying after that cycle was complete.
01:27Then we talk about the actual eye changing.
01:30A visual indication here.
01:32Saturday, we had a pretty small eye, very kind of pinpoint-like.
01:35By Monday, it was much larger because of that eye wall replacement cycle.
01:39But you can also notice the hurricane itself, the storm system, is larger as well.
01:43That's that wind field expanding overall.
01:46That's also why we talk about tropical storm-like conditions being present 200 miles out from the center of the storm.
