Good evening. As we come on the air here on the east coast tonight, temperatures in the buffalo, new york, area are hovering in the upper 40s, heading into 60s tomorrow. After temperatures in the 20s last week that would be welcome news. Except there is the matter of all that snow. Up to seven feet in someplaces that fell last week. Now with rain predicted on top of the warmup, a lot of the snow is turning to water. Tonight flood warnings are in effect for some local creeks in the area and communities still digging out worry they will soon be bailing out. Nbcs Kristin Dahlgren is there to tell us more. Kristin . Reporter good evening, lester. They are getting hit on all sides. First they had to deal with things like this roof collapse under the weight of the snow. Now they have to worry about water seeping in their homes, their basements. This is really just a community that is bracing now with temperatures predicted to go up in the forecast. Near buffalo today, a race against time and mother nature. A scramble to clear roofs and uncover drains before 7 feet of snow melts into even bigger problems. It is unsettling, unnerving and i consider myself a very calm person, but it is very unnerving. Because you dont know how high it will get. Michelle lived through flooding last year. Today her neighborhood is filled with heavy machinery, scooping up snow by the truckload. Reporter this is where they are bringing all of that snow. So far theyve taken about 80,000 tons off the street. But the problem is, it is piling up. The waterways will begin to fill. When we flood it will start to be an issue. Buffalo creek is a concern to the fire chief. 20 minutes it was full of water and now look at it. Reporter the Rushing Water will go right over the banks. The new york governor said they are ready for the worst case scenario. Massive pumps are in place with more stockpiled nearby. Along with dozens of boats. The National Guard is on hand with cases of water and food. Plows are finally getting through to neighborhoods that have been blocked off for days. Even the Buffalo Bills are still digging out, calls to clear out the seats in time for next weeks game. At this time we are currently looking for people to help with snow removal out of the stadium. Reporter for some, there is no amount of digging that will help. Trace george has already lost his companys workshop. There are companies over there and this is the last third i got. After a recordbreaking storm that may not be done yet. I just hope i at least have one building after this is done. To at least still call home. Reporter so it could be a tough 24 hours ahead. Those flood warnings remain in effect. Lester, the creeks are expected to crest sometime tomorrow. Kristin dahl gran tonight. Thanks. For more on what they face in bualo and the rest of the country heading into thanksgiving. Lets bring in Weather Channel meteorologist kelly cast. Good evening.

A few days from now when millions of americans will be traveling on wednesday, snow for chicago and even a rainsnow mix for places like new york, boston, down toward d. C. , rain and thunderstorms across the southeast as well. So lester, it could be a very busy wednesday travel day. Kelly, thank you. Ferguson, missouri remains on edge as it awaits a decision on whether a Police Officer will be charged in the shooting death of Michael Brown. And while the mood on the street is tense, tonight questions revolve around the question that will mean a behind will stay behind closed doors by a 12 member grand jury. Reporter at a church in ferguson, calls for justice for Michael Brown in anticipation of a grand jury decision on whether or not to indict officer wilson and calls for peace, come what may. Nonviolence is the way. Ip dont care that other people on the other side of this argument say you need to just go home and stop protesting, were tired of seeing you protest. This is the way. Reporter with protests now nightly, barriers around the courthouse and police on high alert throughout the region, the seven men and five women of the grand jury are expected back in session on monday. Night win, three black, mirroring st. Louis countys demographics. Nine votes needed on a decision. Possible charges range from murder to manslaughter to no charge at all. In a state that legal analysts say police have more leverage than most when making an arrest. The law as written encompasses a lot of different situations that seem to be at play here in terms of trying to apprehend Michael Brown. Reporter the grand jury is not sequestered and they are likely very aware the nation is watching. I feel sorry for these people they know if they walk out of that grand jury room and have not indicted, they may have created a massive riot in their city and maybe throughout the United States. Reporter the grand jury process itself now some three months long, facing criticism. It is the issue of transparency. People feel like they are being left out of the process. Reporter demonstrators demanded the local prosecutor seen as too close to police step aside and the governor apoint a special prosecutor. Meanwhile the family at the center of this gives thanks, and giving turkeys away in the community that supported. I had to come and give back to the people that everyone is suffering over this. Reporter and in an unusual step, prosecutors say they are showing the grand jury every piece of evidence available and the question is whether there is probable cause to arrest the officer and charge him with a crime. And that is what the protesters want and then letting the officer have his day in an open and public course. Ronal nen ferguson tonight, thank you. Two other Police Shootings are receiving attention.

We travel deep into the rugged andes mountains, 300 miles southwest of bogota, a remote area protected by gorillas.

They destroyed our community and decimated families all up and down the east coast. Reporter we move carefully on a slippery High Altitude trail under the suspicious eyes of local peasant farmers. Before long we come upon a stunning sight. A brightly covered heroin poppy field awaiting harvest next year. They are growing on small four acre plots like this one in the andes mountains. Agents say they are scattered throughout the region but hard to find. Each of the poppy bulbs is slices to extract the milky substance known as latex that is processed in small homemade labs. This is about four acre and will produce about a kilo of heroin for you. Reporter it is then smuggled to the u. S. , either through Central America and mexico or by air and sea routes into the caribbean. Eventually ending up in American Cities along the eastern seaboard, including baltimore. So you have a bunch of deals going on right now over there.
