moving mud off mountains, we've seen this time and time again in haiti, it can be truly, truly devastating. >> reporter: absolutely. and hurricane matthew, when you're comparing it, that was a category 4, hit the southern part of the country last year. anderson, as you know, you've seen these homes, tin roofs, plywood, there are entire families swept away by mudslides. the people think the danger is over when the torrential rains and winds go, but the danger is just coming from the side of the mountain. and that's why i'm saying, as you know, it will take several hours, days to really figure out the impact that this storm, even the back end of it, has had on haiti, already that has dealt with so much in the last few years. >> paula, be careful. everybody on the island of haiti tonight. take a look at this. the dot is a plane, a commercial airliner flying through bands of hurricane irma, flying through an outer band. it got out of puerto rico at the last minute.
