Microburst advisories shall remain on ATIS for how long?

Microburst advisories on ATIS are designed to give pilots timely, actionable warning about a sudden, localized wind-shear hazard. They stay active for twenty minutes after issuance because wind-shear conditions can change rapidly, so the information needs a short, fresh validity period. This twenty-minute window balances being current with avoiding outdated data, ensuring pilots on approach or departure have reliable winds and hazard information. If the threat persists, a new advisory will be issued and the ATIS broadcast updated accordingly. Longer durations would risk pilots acting on stale data, while shorter ones could lead to unnecessary, frequent updates.
