SIH PS26072|Physics-guided multimodal lightning nowcasting

ElectroCast-X forecasts when a developing cloud will first produce lightning, where an active storm will go, and how far to trust it—15, 30 and 60 minutes ahead.

Simulated demo scenario over Odisha

01 / When

Know when a cloud is becoming electrified.

The first-flash countdown combines rapid cloud-top cooling, mixed-phase radar growth, and the −10 °C level into one calibrated forecast window.

Initiation window: 18–27 min

02 / Where

Follow the storm’s likely path, not a single point.

The risk corridor follows observed storm motion and expected growth or decay, widening where the future path is less certain.

03 / How Sure

See which observations support the forecast.

A visible sensor mask keeps uncertainty explicit when Doppler radar, satellite, lightning or NWP forecast inputs are unavailable.
