Turbulence Advisories - Moderate and Severe
These maps indicate where forecasters anticipate turbulence. Green areas are moderate (AIRMETS), red are severe (SIGMETS).
The numbers inside of each area show which altitudes that the advisory is for. For example, 400-240 would mean 40,000 feet down through 24,000 feet (add two zeros to convert to feet). SFC indicates the ground.
