We've added three new weather advisory commands to help you get a fuller picture before and during flight planning.

──────────────────────────────────────────

🌫 /airmet — AIRMETs

What it is: AIRMETs (Airmen's Meteorological Information) are FAA advisories warning of weather conditions significant to light aircraft and VFR pilots — things like moderate turbulence, icing, IFR conditions, and mountain obscuration. They cover large geographic areas and are updated every 6 hours.

How to use it: • /airmet — Show all currently active AIRMETs across the US • /airmet hazard:Turbulence — Filter to a specific hazard type

Hazard types: 🌀 Turbulence · 🧊 Icing · 🌫 IFR Conditions · ⛰ Mountain Obscuration · 💨 Low-Level Wind Shear

📋 /pirep — Pilot Reports

What it is: PIREPs (Pilot Reports) are real-time weather reports filed by pilots in flight. Unlike surface METARs, PIREPs capture actual in-flight conditions at altitude — turbulence, icing, cloud tops, and more. They're one of the most valuable tools for understanding what's actually happening up there.

How to use it: • /pirep KORD — PIREPs within 100nm of KORD from the last 3 hours • /pirep KDEN radius:200 — Expand the search radius up to 500nm

Each report shows the aircraft type, flight level, and severity of turbulence and icing, color-coded from 🟢 smooth to 🔴 severe.

🚨 /sigmet — SIGMETs

What it is: SIGMETs (Significant Meteorological Information) are urgent advisories for weather hazardous to all aircraft — severe convective activity, extreme turbulence, significant icing, and volcanic ash. They are more serious than AIRMETs and require immediate pilot awareness.

How to use it: • /sigmet — Show all currently active SIGMETs across the US • /sigmet hazard:Convective — Filter to a specific hazard type

Each SIGMET shows its series ID, valid time window, affected altitude band, and the direction and speed it's moving.

All three commands include a 🔄 Refresh button to pull the latest data on demand, and detailed help pages are available via /help airmet, /help pirep, and /help sigmet.
