SEVERE WEATHER WATCHES
Aviation Severe Weather Watch Bulletins are teletype presentations identified by the letters
"WW" in the heading. WWs originate from the National Storm Prediction Center, and are
sometimes referred to as Severe Weather Forecasts.
WWs are not issued on a scheduled basis, but rather as required by the progress and development of
severe weather. The forecast period is also variable, again depending on the particular weather. All
times are given in local time, as indicated in the warning itself. When possible, the area of coverage
is limited in size to 10,000 square miles to provide increased accuracy. Aviators may also encounter
a Severe Weather Forecast Alert Message (AWW), which is a preliminary message issued to alert
users that a (WW) is being issued.
