D'Arrigo flood(s) disaster relief

Hello, Friends. The photo you see here are the stairs going to the lower level of my parents house. This is once the water was already being pumped out. You can actually see the line where it was higher. I've been doing my best to keep you all updated on the devastation my family in Oklahoma have been experiencing. My parents, my 3 sisters and my niece have had to move out of their home. They lost everything in this flood. They had a 2 story home. Downstairs was where my 2 sisters and my nieces rooms were. This lower level was filled to the ceiling with water. A complete loss for them 3. All they have is the clothes they had on and the things they had in their purses. My neice was given some clothes by a neighbor, my sister is sharing with my mom, and they're making some trips to KMart. They still can't go into the downstairs level to see if anything was salvagable. Upstairs is damaged as well, with some things being salvaged, but not all. Even the food in their cabinets was ruined and floating around the house. Not only clothes, beds, furniture, computers, couches, Tv's, my nieces toys, washer/dryer, jewelry, but also photos and other things that can not be replaced are completely ruined. I can't imagine going outside to see my life floating away in front of me. I don't have much to help, so I am turning to friends and family. Anything anyone can do to help would be greatly appreciated. Big items will be replaced, my dad's job is putting them in a hotel, but anything I can raise here I would like to donate to my parents, my sister's and my  4 year old neice who's rooms are still under water, and expecting more storms to come. Thank you in advance, from the bottom of my heart. <3
