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.
