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.
