Weatherstem Blast
A directional outdoor warning system that delivers automated audible alerts the moment dangerous conditions are detected. Heard up to 700 yards away, impossible to ignore, triggered automatically so your team does not have to do a thing.
Sound output at 6 feet
How it works
No manual intervention required. Blast handles the entire sequence from threshold detection to all-clear automatically.
01
Blast runs on dual lightning feeds, monitoring 24 hours a day. It also watches NWS warnings and any custom parameters your organization requires.
02
The moment a threshold is crossed, Blast automatically sounds a 117dB alert heard up to 700 yards away and triggers visual strobe warnings simultaneously. No staff required.
03
When conditions improve and your safety protocol is satisfied, Blast issues an automated all-clear. Your team knows when it is safe to resume without guessing.
Every Blast system, Core, Pro, and Ultra, runs on two independent lightning detection networks simultaneously. The NLDN is our primary feed. AccuWeather serves as a live backup. If one goes down, your alerts never stop. No other provider offers this redundancy.
Ask Us About ItThe National Lightning Detection Network, the same system used by the US government and NOAA. The most comprehensive lightning detection coverage in the country.
A live independent backup running in parallel at all times. If the primary feed experiences any disruption, your alerts never stop. Zero gaps in coverage.
Standard on every Blast model. No other outdoor warning provider offers redundant dual-feed lightning detection.
