Puzzle Idea # 1 -- SNOW REMOVAL

"SNOW REMOVAL"

This is the final entry clued as something like "Winter storm response ... or a hint to -x, -y and -z."

The letters S, N, O and W are removed, one at a time, from commons phrases, creating new wacky phrases.

Also, there won't be dupe letters. So, for example, once "S" is removed from "SHOPPING MALL," there won't be another S in the phrase. Which is why "(S)HOOTING STAR" wouldn't work.

For example:
(S) HOPPING MALL -- Destination for teenage potato sack racers? (11)
(N) xxx
(O) xxx
(W) xxx
SNOW REMOVAL (11)

Obviously, these theme entries aren't set in stone.

Thoughts?
