Function parseSigmetBulletin

Recommended entry point for SIGMET parsing. Handles both single SIGMET records and multi-SIGMET bulletins, always returning an array.

Consumers do not need to know whether their input is a single record or a bulletin - this function handles both transparently. Real-world convective SIGMET bulletins from AWC often contain multiple individually numbered SIGMETs for a region, followed by a shared outlook section. This function splits the bulletin, parses each SIGMET, and attaches the shared outlook to each convective SIGMET.

For non-convective and international SIGMETs (which are typically single messages), this returns an array with one element.

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

const sigmets = parseSigmetBulletin(rawBulletin);
for (const sigmet of sigmets) {
  console.log(sigmet.format, sigmet.raw);
}
