They will be providing you the latest, minute-by-minute, online as always. And out west, 100 people missing, a race against time to find them. These images of those who were rescued, a 4-year-old boy. The devastation below. Impossible to turn away. And tonight, we are hearing from survivors that the mud struck with lightning speed, rising up to their chests. ABC's Neal Karlinsky is there. Reporter: Hovercrafts joined a small fleet of helicopters today over what looks nothing like a community. Looking for any signs of life amidst a disaster so chaotic, officials haven't accounted for 108 people and aren't sure what the total number of missing really is. The situation is very grim. Reporter: Pictures from the scene leave little clue that 30 homes once stood here. Robin Youngblood said living through it was like whirling in a washing machine of mud and trees. We were tumbled inside and had mud in our eyes and nose and mouth. I'm really grateful I'm alive. Reporter: The scale of it all is simply mind-boggling. From here, you can see trees that are 50 feet to 60 feet tall, that have been tossed around like toothpicks and thrown hundreds of yards. The mudslide started here on this ridge, a square mile-sized chunk broken loose. Cascading over this valley. Take a look. The community before, dotted by houses, to the left of the river. And today, all-mud, leveling everything in its path. The area's only school was closed today. Many of their students lived in the slide zone. This school may have been the hardest hi Well, it's not just the school. It's the town and the community. Reporter: Tonight, some rescue crews are being forced to pull back, fearing more slides in the same area. Neal Karlinsky, ABC news, Darington, Washington. And we want to know what's ahead. Let's bring in ABC's meteorologist, ginger zee, right now. Ginger? There's more slide risks. And this is why. We've had a very wet month in this part of the nation. Look. Average is just over 4 1/2 inches of rain for the month for this spot. This March, we've already had over seven. If we get to 9 1/4, we break an all-time record. And that's possible. The next couple of days. We take this through Friday. There's going to be very heavy rains, especially northwestern California. That area could see up to three inches through Friday. That would be an issue. And the buzz on the east coast, Diane, is all about this nor'easter. That's what we've been hearing all about, right? You wonder, will it affect me? Let's time it out. When this storm comes together, it's a Tuesday night into Wednesday deal. New Jersey to New York starts to get it late Tuesday night into early Wednesday. It's very low snow totals. The bulk of it going to affect coastal new England. The cape in a blizzard watch. Parts of Maine in a blizzard watch. It's going to be 60-mile-per-hour winds and the cold that follows. Diane? Thank you for the picture, coast-to-coast, ginger zee.
