Flash integrations: every place a prediction can land
The same 1×1 km forecast reaches people as app, SMS and email alerts, reaches the field as a horn or a strobe, and reaches your own systems through the Flash API, webhooks and Flash Agent connectors. One model run behind all of them, so a webhook and a push alert never disagree about a site.

Alert channels · Included on every plan
Which alert channels does Flash send to?
SMS, email and the app are included. Every channel reads the same 1×1 km cell from the same run, with lightning refreshed every 2 minutes and hail every 5.
Flash mobile app
Predictive lightning push notifications, an All Clear map and 18 hours of future radar, for every user at the site.
SMS
Text alerts to the people on each site, included on every plan.
Email
Email alerts, included on every plan alongside SMS and the app.
Weather Command Center
Every site on one map, with role-based alerts (athletic trainer, superintendent, foreman) and a portfolio-wide audit log.
On site · Horns and strobes
Which horns and strobes can Flash trigger?
Legacy detection units sound after lightning is already nearby. Flash hardware and relays fire from the predictive lightning model, so the signal comes before the first strike, not after it.
Flash Weather Shield
Four horns standard (up to eight) for whole golf courses and complexes. Solar-powered with cellular connectivity, wired to the 1-hour predictive lightning model.
Shield Mini
A compact two-horn unit for clusters of soccer or baseball fields, often near busy roads.
Shield Micro
A multi-colored strobe for pool decks and patios: green for all clear, amber for warning, red for alert. The siren can be removed for quiet zones.
Horn and strobe relays
Relays to the horns and strobes already on site, added per site. The relay fires from the same rule as the app, so a horn never sounds for a different reason.
Flash API · Webhooks
What can your own systems pull from the Flash API?
Over 100 parameters as JSON, per 1×1 km cell, with forecasts out to 180 hours. Subscribe a threshold per site to a channel or a webhook URL, and route alerts to horn and strobe relays, PA systems, Slack, Teams or your own stack.
