StormZ Risk Assessment - Storms do not begin when they are named — they begin days earlier.
Major Storms Risk Forecast
StormZ identifies early-stage atmospheric conditions that precede storm development.

Repeated observations show persistent risk signals emerging days before storm formation.
How to read StormZ maps
White spirals = rising storm risk.
Larger = more imminent. Clusters = potential storm pathways. Black circles = hurricanes.

StormZ Data Signals
StormZ tracks evolving atmospheric structures associated with tropical cyclone formation.
Each day, candidate storm systems are detected, scored, and tracked forward in time to identify risk drift, persistence, and potential genesis windows.
StormZ combines satellite-derived atmospheric signals with historical storm data to estimate where and when storm development may occur.
Data sources include NASA MERRA-2, EU ERA reanalysis, and NOAA IBTrACS storm records.
What StormZ Shows
The StormZ map displays daily storm-risk drift derived from tracked atmospheric candidate groups.
Each visible spiral represents a persistent atmospheric structure that has shown signals associated with storm development.
Risk structures are detected from divergence patterns between total column water vapour (TQV) and outgoing longwave radiation (OLR) — a known indicator of convective activity.
Clicking a spiral reveals the candidate’s estimated genesis window, persistence history, and associated atmospheric signals.
