A text when lightning is detected within 20 miles of your site, another at 15, and the stop-work call at 10 — each with the distance and direction of the closest strike, plus any National Weather Service thunderstorm forecast or watch in effect for that address. When a cell is heading your way, the crew winds down on your schedule instead of scrambling on the storm's.

Each stage sends once per storm. No repeats, no chatter — every text you get means something changed. The three warning texts also carry the National Weather Service forecast for your address, looked up fresh each time, so any one of them stands on its own.
Lightning detected in the area, with distance and direction. No action required yet.
It's closing. Start winding down cranes, work at height, and anything slow to make safe.
All outdoor and crane operations stop — the distance in OSHA/NOAA guidance.
Thirty strike-free minutes inside the radius, then work resumes. Every new strike restarts the clock.
Not every storm announces itself. A cell that forms directly overhead can put lightning inside 10 miles with nothing detected further out — those sites get the stop-work alert first and nothing before it. The early stages are what we can see coming.
No weather stations to mount, no apps for the crew to download. If your foreman can receive a text, you're covered.
Enter the job site address and the phone numbers that should get alerts. We geocode the site and watch the airspace around it around the clock — out to 20 miles, not just the 10-mile stop-work line.
Lightning inside 20 miles sends an advisory; inside 15, a watch. Each names the distance and direction of the closest strike, alongside what the National Weather Service has published for your address — the hours thunderstorms are forecast, any watch or warning in effect, and your site's closing time if you've set operating hours. One text per stage, per storm — no spam.
A strike inside 10 miles is the stop-work call. Then, after 30 consecutive strike-free minutes — the OSHA/NOAA-recommended wait — every contact gets the all-clear, so work resumes without guesswork.
Purpose-built for superintendents and safety managers who need a defensible lightning procedure — not another dashboard to babysit.
Three tiers instead of one, around your exact site coordinates — not a county-wide weather alert. The early tiers are the part a person standing on site can't do for themselves.
Each warning carries what the National Weather Service has published for that exact address — the hours thunderstorms are forecast, any watch or warning in effect, and when your site is due to close. The near view and the longer one in a single message, so nobody opens a weather app to decide whether to pull the crew. We relay the Weather Service; we don't forecast anything ourselves.
Every new strike resets the clock. The all-clear only goes out after a full 30 strike-free minutes, matching OSHA 3863 and NOAA guidance.
Each site gets a shareable status page with a live strike map, radar overlay, countdown, and the next twelve hours from the National Weather Service. Pin it in the crew group chat — no login needed.
Add multiple phone numbers per site — foreman, superintendent, safety manager. Every contact gets every stage at the same time, so nobody is waiting to be told.
Plain SMS. No app to install, no accounts for field crews, nothing to keep updated. It works on a flip phone in a dead zone of app-store coverage.
Every strike, alert, and all-clear is logged with a timestamp. Export a clean PDF report for any date range — ready for OSHA inspectors, insurers, or project owners. Still need the written procedure itself? Start from our free jobsite lightning safety plan template.
Every plan includes full monitoring, staged SMS alerts with the National Weather Service forecast, all-clear timers, and live status pages. No contracts, no sales calls — cancel anytime.
Prices are per company, not per user. Annual billing works out to roughly two months free.
