Function parseSigmet

Parses a single SIGMET record into a structured Sigmet object.

For general use, prefer parseSigmetBulletin which handles both single records and multi-SIGMET bulletins transparently.

Automatically detects the SIGMET format (convective, non-convective, or international ICAO) from the content and returns the appropriate variant of the discriminated union.

Accepts both raw WMO-wrapped messages (with header lines like WSUS32 KKCI) and body-only messages.

import { parseSigmet } from '@squawk/weather';

const sigmet = parseSigmet('SIGMET NOVEMBER 3 VALID UNTIL 050200Z\n...');
if (sigmet.format === 'NONCONVECTIVE') {
  console.log(sigmet.seriesName, sigmet.hazards[0].hazardType);
}
