Weather Alerts

Change-Driven Alert Detection

AeroSentinel's Weather Alert system monitors your watched airports around the clock and notifies you when a report actually changes. Unlike basic weather apps that simply display current conditions, the alert engine compares every incoming TAF, METAR, and SPECI against the last version it saw, so an alert always means something new happened, not just that a routine report was reissued.

When a changed report arrives, the engine checks it for LIFR-level visibility and ceiling, hazardous reported or forecast phenomena (thunderstorms, freezing precipitation, hail, squalls, dust and sandstorms, blowing snow, funnel clouds, volcanic ash), and strong or gusting wind, evaluated against each airport's actual runway headings as headwind and crosswind components.

Alert Types

Each alert corresponds to a specific kind of report or condition:

• TAF Amendment (AMD): triggered when a TAF is amended, indicating that the original forecast was significantly different from evolving conditions.
• TAF Correction (COR): issued when a TAF contains an error that has been corrected by the issuing station.
• SPECI Report: a special weather observation triggered by rapid or significant changes between routine METAR cycles.
• LIFR: visibility or ceiling at Low IFR levels in the current report or an active forecast period.
• Extreme Weather: reported or forecast phenomena with direct operational impact, from heavy thunderstorms and freezing rain to hail, squalls, and volcanic ash.
• Wind (Caution / Severe / Extreme): tiered wind alerts computed per runway, so a 25-knot direct crosswind and a 25-knot headwind are treated differently.

Notification Delivery

Alerts are delivered through multiple channels to ensure you never miss a critical update. On desktop and mobile browsers that support push notifications, AeroSentinel can send instant pop-up alerts even when the tab is in the background. The alert toast appears on-screen with the airport identifier, alert type, and a summary of what changed. You can acknowledge alerts to mark them as reviewed, or tap "View Changes" to see the full before-and-after comparison.

All alerts are also logged in the dedicated Alerts Dashboard, where you can browse, filter, and review historical alerts. The dashboard supports filtering by airport, alert type, and acknowledgment status, making it easy to manage high volumes of alerts during busy weather events.

Configurable Monitoring

You have full control over which airports are monitored through the Personalized Watchlist feature. Add airports by ICAO code, and AeroSentinel will begin tracking weather reports at those locations immediately. This targeted approach means you receive alerts only for airports that are relevant to your operations, reducing noise and ensuring that every notification carries actionable information.
