SIGMETs

SIGMETs by ICAO prefix

Retrieves all active SIGMETs within the specified ICAO prefix using IWXXM 1.1.

For a list of possible ICAO prefixes refer to the Reference Data APIs.

Response includes:

  • Affected FIR
  • Phenomenon and expected change in intensity
  • Geometry of area affected by the SIGMET (where available)
  • Direction and speed of motion (when the speed of motion is unknown a value of -999 is given)
path Parameters

required
string

The letter of the ICAO prefix

query Parameters
