Figure 3-2 Military Weather Advisories (MWA) Area Valid Times
Advisory areas are enclosed by dashed lines and identified by block letters. Each area has a color
associated with it to indicate the type of hazard to flight, for ease of identification:
TORNADOES AND SEVERE THUNDERSTORMS
GUSTY SURFACE WINDS
The RED, BLUE, GREEN, and ORANGE correspond to the intensity of the thunderstorms based
on wind speed and hail size. For example, MWA RED and BLUE areas correspond to conditions
for which the NWS would issue a WW.
Each individual advisory area will be listed along the outer edge of the chart with its
corresponding valid time(s) and maximum tops expected. Areas forecast to have liquid or freezing
precipitation will include amounts expected. Additionally, MWAs use standard weather
abbreviations to describe coverage for a forecast area, as listed in Appendix C.
