StormZ Basin Intelligence

June 2026

North Atlantic

Early June atmospheric preconditioning developed across the Gulf region, preceding Hurricane Arthur. During late June the basin has generally quietened, with residual risk centred over the western Atlantic. StormZ is now identifying renewed atmospheric preconditioning extending westwards from the African coast into the tropical Atlantic, suggesting increased monitoring through early July.

South Pacific / South Indian Ocean

Early June showed elevated atmospheric risk across the central South Indian Ocean. Since then the basin has become comparatively quiet, consistent with the seasonal decline in tropical cyclone activity. No significant basin-wide development is currently indicated.


StormZ identifies atmospheric preconditioning associated with tropical cyclone formation. Basin Intelligence summarises the current evolution of atmospheric conditions and highlights regions requiring operational attention.

StormZ Risk Assessment - Storms do not begin when they are named — they begin days earlier.   

StormZ detects atmospheric instability patterns that precede storm formation
Water vapour and longwave radiation divergence.
Convection amplitude and late-stage spikes.
Rotational instability and structural persistence.

Basin active: Africa ↔ US East Coast — Outcome: Hurricane formation highly likely    → Read More

Persistent instability (Africa) — Persistent instability (US East Coast) — Basin coupling → elevated risk

Repeated observations show persistent risk signals emerging days before storm formation and genesis.   → About StormZ

How to read StormZ maps
storm White spirals = rising storm risk. Larger = more imminent. Clusters = potential storm pathways.
