Reno and Sparks decided to adopt three cities because each one has specific requests for needed items ranging from diapers to paper napkins.
They say they expected to fill one truck completely with all the supplies needed, but they've received so many donations they now say they will definitely fill three trucks, maybe more.
Just this afternoon, someone came by with hundreds of tools.
Officials in Gretna, Louisiana, along with Ocean Springs and Moss Point, Mississippi, say their residents have received clothing and food, but other items needed on a day to day basis are impossible to find.
Terri Hendry, with the City of Reno, says this is why it is so important to make sure those residents recieve the supplies.
"The Reno community is giving everything from paper products to hygiene products, those personal items you would normally run out to the store and get. But, you have to understand, these people can't run out to the store because there's no store that's stocking things right now. Many things are still not open for them."
The trucks will leave Monday morning for the Gulf Coast.
