Retrieve current SIGMETs, G-AIRMETs, and convective outlooks for a region from the aviationweather.gov Data API

Steps
Call the /api/data endpoints (e.g. /api/data/airsigmet, /api/data/isigmet) with region/type filters such as conv (convective SIGMETs), turb, icing, or ifr.
Choose a response format (raw text, JSON, GeoJSON, or XML) appropriate for downstream parsing or map rendering.
Set a custom, identifying User-Agent header to avoid being caught by automated traffic filtering.
Combine with the PIREP/AIREP endpoint if correlating pilot-reported conditions with active advisories.
Respect the documented rate limit of roughly 100 requests per minute per client.
Known gotchas
No API key is required, but requests without a proper User-Agent can be mistaken for abusive automated traffic and blocked.
SIGMET/AIRMET products have different geographic and temporal validity rules (e.g. convective SIGMETs are US-only, valid for limited windows) — don't treat all advisory types as interchangeable.
Exceeding the ~100 requests/minute limit results in temporary access blocking, so batch/cache queries rather than polling in tight loops.
