Storm tracking & trajectories

A power line.
Dead center.

You had driven 2 hours. The storm was perfect. But the spot, picked in a rush on the roadside… The best lightning of the evening, behind a power line.

What if you knew exactly where the storm was heading?

Storm Predict — Real-time map with active storms

5 storms tracked simultaneously · Mediterranean · Real-time

Why you're always too late.

You check the radar, the models, three apps. None tells you where the storm will be in an hour. So you drive on instinct.

The radar shows the past

Classic services show where the storm was ago. Not where it'll be. You're always late.

25 km of blur

At that resolution, your town and the next one are the same pixel. Impossible to pick a spot.

Too late to react

The alert drops when the storm is already here. No time to move, no time to find the right angle.

This one hits Auch
in 47 minutes.

A white line on the map. The confirmed trajectory. The danger corridor. You have time to find the perfect open field, set up the tripod, and wait.

  • Automatic detection, from first cell to dissipation
  • Real-time classification: ordinary, supercell, squall line
  • Confirmed trajectory up to 4 hours
  • Alerts on your favorite spots
Storm trajectories with danger corridors

Every kilometer matters.

Storm Predict uses AROME data from Météo-France — 1.3 km resolution. When others see a county under the storm, you see which road to take.

I was pleasantly surprised by the interface — aesthetic, clean, exactly the kind of tool you want to use in the field. I really like the Flash Rate, it instantly tells you the intensity of electrical activity. Impressive work.

Frequently Asked Questions

What is Storm Predict?

Storm Predict is a real-time storm tracking platform that automatically detects storm cells, calculates their trajectories up to 4 hours ahead, and sends personalized alerts. Built by a storm chaser, it uses Météo-France AROME data at 1.3km resolution.

How do trajectories work?

Trajectories are calculated from atmospheric wind data (AROME 1.3km model) and past movement analysis. The system produces a confirmed trajectory (white line) with a danger corridor and hourly predictions (+15min, +30min, +1h, +2h, +4h).

How much does it cost?

4 plans: Discovery at €9.99 first month, Monthly at €24.99/mo no commitment, Seasonal at €129 for 7 months (April-October), and Annual at €199 for 12 months with priority support.

When is it available?

Official launch April 3, 2026 at the Storm Chasers Festival in Bron (Lyon, France). Early access registrations are open.
