Questions crews ask

Illustrative example · not live weather

Others predict, Flash knows

Reactive detection. We’re Proactive.

Detection tools tell you where lightning was. Flash tells you where it will be, up to an hour before, one kilometre at a time. That is the difference between reacting and deciding.

Everyone else reacts. Flash knows.

Detection-based tools compared with Flash prediction
Everyone elseFlash
Comparison 1 of 5

Detects lightning once it's already here

The first alert is the first strike.

Predicts it up to an hour before it strikes

Every cell is scored 60 minutes out, so the call is made early.

Comparison 2 of 5

County-level forecasts

One answer for every site in the county.

1×1 km, field-level precision

Each site gets its own cell and its own answer.

Comparison 3 of 5

Updated hourly, or slower

The storm moves faster than the map.

Refreshed every 2 minutes

The map moves with the storm, not behind it.

Comparison 4 of 5

"Chance of storms this afternoon"

A percentage and a shrug.

"Lightning reaches this field at 3:47"

A place, a time, a decision.

Comparison 5 of 5

React and hope

Clear the field after the first flash.

Decide with confidence

A GO or NO-GO with the time attached, and a log to prove it.

How it works

How does Flash know up to 60 minutes early?

  1. A weather radar dome on a hilltop under storm clouds

    30+ integrated data signals

    Radar, satellite, surface observations, lightning climatology and model fields, ingested continuously for the continental U.S.

  2. Gold and blue signal lines flowing across a screen, a picture of the lightning model

    The signals that precede a strike

    FirstStrike for lightning and Predictive Hail for hail distil them into the signals that come before a strike, not the ones that follow it.

  3. A supercell storm towering over a grid of farm fields

    1×1 km cells, refreshed every 2 min

    Risk is scored for every 1×1 km cell out to 60 minutes, with a 5-hour lightning probability for the day's schedule.

  4. Flash Weather Shield siren installed on a golf course

    Alerts where the call is made

    App, SMS, email, horn and strobe relays and the API, with an all-clear timer so play resumes on evidence, not a guess.
