Enough airspace. Refer to this Area Forecast (FA) example:
Eastern ... 2,000 feet overcast, layered to flight level 250. Widely scattered light rain and snow showers. Wind northwest 20 gusting to 30 knots. 5pm UTC (17Z) 5,000 feet broken. Wind northwest 20 gusting to 30 knots. Outlook: VFR wind.
The FA's categorical outlook, 18 hours in the future, says, "VFR wind (contraction WND)," so you can expect winds or gusts of (_____) knots or greater. (Fill in the blank, and think conterminous U.S. -- CONUS.)
