Back now here on "Gma." Thousands of Americans still trapped in the caribbean after hurricane Irma. Let's take a look at these images. Some people were able to evacuate. Others were not so fortunate. The U.S. Virgin Islands also seeing extensive damage and ABC's Linzie Janis saw it up close with the coast guard. She is now in San Juan, Puerto Rico. Good morning, Linzie. Reporter: Good morning. This is the first time we have been able to get our boots on the ground in one of these devastated islands and the detux to St. Thomas is massive. Hurricane Irma ripping through there as a category 5 damaging almost every structure we saw leaving people without power, drinking water and growing increasingly desperate. This morning, our first look at the devastation in the U.S. Virgin Islands from the ground. It's going to be a little rough on the way over. Reporter: This U.S. Coast guard team is doing an aid drop bringing everything from generators to food, water, clothing and law enforcement personnel to help with the security situation here. As we drove through the streets, utility poles and power lines downed everywhere. Trees stripped bare. This once green lush landscape now looks like this, dead trees everywhere and debris like this overturned car. Windows blown out, roofs ripped off, buildings crumbling under Irma's force. We're inside a church here in St. Thomas, just look what Irma did to it. That was the altar. The entire front of the building gone. Tourists and residents desperate to get off the island. But with the airport destroyed, the only way off is by boat. I've been told there are a couple of cruise ships coming in tomorrow that are taking people to Puerto Rico. Reporter: Government planes and choppers landing only for emergency evacuations and to drop off personnel and supplies. While we were on the island, police responding to looters. Attempting to raid a shipping container. A curfew in place between 6:00 P.M. And noon. Some of the 1200 tourists so far evacuated from St. Thomas by the National Guard telling us about the dangers that emerge after the storm. Maureen puckeren said robbers wielding#long swords invaded her hotel. They started stealing food from our fridge and then they beat up one tourist. Hit a lady in the eye and then they robbed the bank down the block and ran into our compound. Reporter: Of course, some of the looting is just people getting what they need to survive but clearly criminals are taking advantage of this situation. It's becoming a very dig problem. Today with hurricane Jose out of this area, the U.S. Military resumes trying to evacuate the thousands of Americans that remain stranded. Robin. All right, Linzie, we got to keep in mind these smaller islands impacted, devastated. Leveled in many places. Lat ittest on Irma's path.
