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 5 minutes ago. Not where it'll be. You're always behind.
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.

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
The whole storm, on one map.
Flash rate, reflectivity, steering wind, shear, risk indices, alert history. Everything you need to decide in the field, on a single screen. High-resolution models wherever they're available (AROME in France and almost all of Spain, HRRR in the US, and more every season), composite radar and Doppler to back them up. When others see a region under the storm, you see which road to take.

Built by a storm chaser, for storm chasers. Not a generic weather service. A field tool.
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 leverages high-resolution models (AROME in France and almost all of Spain, HRRR in the US, and more every season), composite radar and Doppler.
How do trajectories work?
Trajectories are calculated from atmospheric wind data from high-resolution models and analysis of the cell's past movement. 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?
3 plans with the exact same features, only the duration changes: Monthly at €9.99 first month then €24.99/mo no commitment, Seasonal at €129 for 7 months (April-October, ~25% savings), and Annual at €199 for 12 months (~33% savings).
What geographic coverage?
Storm Predict covers the entire world. Automatic tracking detects and follows storms on all continents in real time via the Blitzortung lightning detection network, backed by the most accurate local models and radars available in each region.
