SIGMET

The image updates every hour with latest information about issued SIGMET's.

SIGMET messages are warning messages issued for specific meteorological phenomena that may affect aircraft in flight. Each phenomenon is identified by a single letter, while differentiation between individual messages and flight information regions (FIRs) is made by means of numerical sequencing. For example, the first SIGMET of the day issued for turbulence (TURB) over Greenland is assigned the number U01. If an additional SIGMET for turbulence is issued later on the same day for another area within the region, it is assigned the number U02, and so forth. Each meteorological phenomenon is assigned a specific identifying letter in accordance with AMC1.MET.TR.250(c).
