Meteorology

If we have any doubt about whether the weather is suitable for flying, we

typically say, "If in doubt, don’t fly."

If a SIGMET has been issued, there is dangerous weather in that area.

3.9.1.1 SIGMET

When weather conditions are or could be dangerous for flight, a SIGMET

(Significant Meteorological Information) is issued. A SIGMET is a meteorological
report about important weather conditions that can affect flight safety.

SIGMET reports describe dangerous or severe weather phenomena such as:

- Thunderstorms and turbulence

- Icing

- Volcanic ash

- Poor visibility due to weather conditions like fog or sandstorms

- Strong winds and other hazardous atmospheric phenomena

The table shows the 13 weather phenomena for which SIGMETs should be

issued.
