AWN Features

Weather Safety Package

The KestrelMet 6400 WBGT delivers complete weather safety in a single, connected system. With the Ambient Weather Network (AWN) Weather Safety Package, you get real-time heat stress monitoring, a lightning detection system (LDS) up to a 60-mile radius, live National Weather Service alerts (coming soon), and instant SMS notifications for the custom thresholds you set — all under one subscription. Keep your team ahead of every storm, every shift, every season.


How Lightning Watch Works

Is practice starting? Do you have an outdoor event? Activate LDS to monitor lightning for up to 4 hours. The AWN Lightning Watch monitors three detection zones simultaneously, giving your team the right warning at the right time:

  • Close Range (0–10 mi) — Immediate danger zone. Alerts fire the moment a strike is detected nearby.
  • Medium Range (10–45 mi) — Approaching storm window. Get ahead of the threat before it arrives.
  • Long Range (45–60 mi) — Early-warning horizon. See what's coming while you still have time to act.

A countdown timer shows exactly when conditions are clear — no more guessing when it's safe to resume.
