“WND” in the categorical outlook in the Aviation Area Forecast means that the wind during that period is forecast to be
sustained surface wind speed of 20 knots or greater.
Area forecasts generally include a forecast period of 18 hours and cover a geographical
area the size of several states.

What information is provided by a Convective Outlook (AC)?
It provides an outlook on convective turbulence over an 8 day period.
You would review a convective outlook to find information on
areas of slight, moderate or high risk of severe thunderstorm activity.
Your weather briefing for a cross-country flight indicates an active Convective SIGMET that was issued two hours prior to departing for your destination. Your estimated flight time is 2 hours. This SIGMET
will expire before your scheduled arrival time.
If you encounter a convective SIGMET, you should consider the possibility of
embedded thunderstorms, severe thunderstorms, and heavy precipitation.
When are severe weather watch bulletins (WW) issued?
Unscheduled and issued as required.
Hazardous weather (e.g., IFR, icing, turbulence, etc.) meeting AIRMET or SIGMET criteria
must be used in conjunction with the FA to determine hazardous weather information for the flight.
During the weather briefing, you are informed that there is a fast moving low pressure trough that is expected along your route of flight. In this case, you should anticipate
the possibility of severe weather.
