Rocky Road

We can conclude a couple of things from this blurb:

1) Downstyle is Better Than Upstyle
2) We do not need a private-sector naming system for winter storms

If you know enough about that strange new habit to recall that the most recent winter storm was named Q, you can probably get "Winter Storm Rocky" as a noun phrase modifying "road closures." If not, you can be forgiven for getting things mixed up with ice cream. Either way, it's hard to see why the name of the thing, real or not, is supposed to be more attention-getting than "road closures" -- or piles of snow, or howling blizzard winds, or anything else that your poor audience might find interesting.
