Before piling the family in the car and heading to Greensburg this morning, the United Way wants you to call first and see where and how you're needed.
In Kansas, call the United Way's hotline at 211. Outside of Kansas, call 888-413-4327.
The hotline is staffed 24/7 with United Way workers who can tell people wanting to help where they're best needed.
"If needed, they'll be asked to come out -- and if they're not, they'll be told when they can come out," said Sharon Watson, director of public affairs at the Kansas Adjutant General's Department. "This is going to be a long-term effort and there will be many needs now and in the future."
Much of the work this weekend will involve heavy machinery and dangerous work, said Delane Butler, spokesman for the United Way.
"It will be later on that we'll really need people to come out and help do walk-throughs on people's properties," he said.
Once volunteers arrive in Greensburg, AmeriCorps will coordinate their efforts, Butler said.
"I don't think they need a lot of individuals over the next few days, so we're continuing to encourage people to not just show up," he said. "If people are interested, they do need to call ahead of time."
