Transcript for How Hurricane Harvey compares to Hurricane Katrina
Joining us from Baton Rouge is retired lieutenant generousle -- russel Honore. 12 years ago this coming Tuesday. Thanks for joining us. I know you've been through this before from Katrina. From your standpoint what is the largest challenge when it comes to relief efforts from this point onwards? Well, it will be working through the weather. Continuous flooding, we'll continue to take roads that would be available for surface high water rescue vehicles to get through and the wind. Wind will take the helicopters out of the air and they won't be able to do what they do best which is to do broad area search, scan and rescue. So this for the next 12 hours if this storm -- until it Tran significants to a tropical storm, from a hurricane it going to continue to cause challenges and damages. It's going to continue to take infrastructure down. As it continues to circle dark make that circle in and around the Texas, southern coastline and this widespread flooding, rural roads, much of this area is rural as the rivers swell it'll take bridges out, some of those bridges could be damaged beyond repair and the only W to get across them is by boat or by air and the fact that we may not be able to use our air search and rescue for not only hours but maybe days, in comparison after Katrina, within four hours after the eye passed and Katrina came through new Orleans and through the Mississippi coast, we had helicopters up doing search and rescue. This will not be the case. It may take days before we can get our helicopters up to do the broad search and rescue missions. But there are a couple of tips we need to share with people if you would like at this time. And, russel -- Hello. Yes, we can hear you. The big concern is the water and the rain and the need for water rescues which usually is an immediate need and as you're pointing out the weather may not allow search and rescue to get in and you were offering tips for people. Yeah, now, power lines, many rural and small communities will try to leave the grid up. The conventional wisdom is take the grid down. That's the safest thing to happen as well as shutting the gas off because as long as that gas stay on and you have electricity in parts of these small towns, communities and counties, you're going to have the -- it's going to increase the probability of fire. So the grids need to come down. The conventional wisdom in a lot of communities in response is to let's see what stays up and leave that part of town with electricity and gas. But collectively more people will get hurt and you're going to lose more property by having gasoline and electricity going in the buildings that are flooding and this problem is going to get bigger. It may extend as far north as San Antonio and certainly cover most of Houston. But as those grids become covered with water and water surrounds buildings at the bottom, that electricity need to be cut off or people are going to get -- increase the probability of fires to the building and people getting hurt. Phone systems, those people who are still watching and have access to this information, stop using the dial on the phone. Use text to tell people you're okay. If you check in on relatives in the surround areas in this flood zone and affected area use text as opposed to dialing, that system is significantly -- Well, we're having technical difficulties with general Honore there. He just -- a repository of wisdom when it comes to this kind of situation. So many lessons learned from Katrina and life-saving advice there. I hope everyone was listening to that.
