This is called staging, and there's three reasons why you wouldn't do it.
First, they don't want to tie up their trailers letting them sit loaded until a natural disaster happened. Wal-Mart doesn't have the trailers to spare--their whole logistics system revolves around drivers picking up a trailer at the DC, taking it to a store, dropping it, picking up a different trailer and taking it back to the DC where they drop it, hook to another trailer and deliver it to a store...
Second, they don't want to pay people to load trailers just in case they might need to ship supplies to a relief operation. In some years, there are no major natural disasters that require Wal-Mart's assistance in the relief operation. If 2005 was one of those years and they'd have staged all this stuff in trailers, they'd have had to pay those same people to take the stuff back off the trailers.
And third, the stuff stays in better condition in a climate-controlled DC.
Wal-Mart's distribution centers are so automated and the people so well trained, if Wal-Mart's assistance in a relief operation is needed they can have a trailer loaded and on the road in an hour or so. It makes no sense at all to just stage trailers in case they might be needed.
