What It Does

Five minutes before the sky breaks.

Tell the bot your neighborhood. It watches the radar specifically for your block. When a storm cell is heading your way, you get a "leave in 12 minutes" alert — early enough to skip the stranded-soaked moment.

I

Hyperlocal radar

Not your city — your neighborhood. The bot reads radar within ~2 km of your registered home and ~2 km of your registered work. Different cells fire different alerts.

II

Leave-now cards

When the model predicts rain at your location in <15 minutes, you get a single card: leave now if you're getting wet matters. No spam, no "chance of rain 30%" hedging.

III

Group forwarding

Forward the card into your work group or family group with one tap — "leaving early today, see attached." Everyone in the group sees the same radar snapshot.

An Alert

What lands when a cell is heading your way

Time. Location. Severity. Forward button. No fluff.

Work / Family Group

One alert. The whole group dodges the storm.

Add Monsoon Radar to your work or family group. Everyone's registered neighborhoods get covered. When a cell threatens any of you, the group sees it.
