COSTELLO: Unbelievably big -- that's how emergency crews describe a massive mud slide on the western slopes of Colorado. Four miles long, two miles wide and about 250 feet deep. This entire area remains very unstable. Right now three people are missing. One witness said the mudslide sounded like a freight train. Meteorologist Jennifer Gray joins us now to tell us exactly where this is. Good morning.</s>JENNIFER GRAY, AMS METEOROLOGIST: Good morning to you. Yes, it just happened right outside of Culver, you can see in Colorado. A lot of rain has fallen in the past 24 to 48 hours. This is radar from the past 24 hours. We'll zoom in a little bit and concentrate it right over that one area. Those showers came through yesterday and even on Saturday evening. This is the rainfall totals about an inch of rain which doesn't seem like a lot but if the ground is already so saturated, it's not going to take a lot more to cause some of these landslides out there. The area is still very unstable. Of course, the good news is the system that caused the rain in portions of Colorado is going to be pushing out as we speak so conditions should be improving. We're going to get more of a dry pattern as we through the next couple of days to let the area dry out some. What happens is the ground just gets extremely saturated from the rain and because the slope is so steep, it can't hold the weight of the water within the soil and that slope fails so that's where you get those landslides unfortunately. The good news is it looks like we're going to dry out a little bit for the next --</s>COSTELLO: That is better news. Thanks so much, Jennifer.</s>GRAY: Right.</s>COSTELLO: Still to come, this Memorial Day we pay tribute to service members who paid the ultimate sacrifice. President Obama arrives at Arlington National Cemetery in moments. You'll see it live.
