Lessons learned from Katrina

Here are some style notes I've collected. Feel free to e-mail me more (or add them to the comments), and I'll add them here.

• Underwater is one word as an adjective or adverb.
• Floodwater is one word.
• Buses has only two S's.
• Tropical-storm-force winds needs two hyphens.
• Canceled has only one L.
• Levees are breached, not breeched.
• Beware the abundance of adjectives. (Remember "show, don't tell"?)
• Mph is acceptable in all references to miles per hour or miles an hour.
• Whiskey has an E when it stands alone, but it's Scotch whisky.
  

And this isn't a rule that I can find, but it makes a lot of sense to me. So, here goes: There's no need to hyphenate mph, even as a modifier: Winds held steady at 35 mph and The 35 mph winds held steady. This follows the same pattern as dollars, percentages and millimeters.

Any arguments or additions?
