Real-time coverage of severeStorms event — Tropical Storm Marie — Pandita Data.
⛈️ OPEN LIVE 3D WEATHER ALERTSTropical Storm Marie intensified rapidly over the eastern Pacific Ocean on 2 September 2026, positioned at 17.7°N, 112°W with sustained winds exceeding 50 knots, bringing dangerous moisture and gusty conditions toward western Mexico and the southwestern United States. The storm poses an immediate threat of flooding, rip currents, and hazardous seas across coastal regions of Sonora and Sinaloa, Mexico, and potentially Arizona and New Mexico through heavy precipitation bands reaching inland.
Tropical cyclones in the eastern Pacific form when warm ocean waters (typically above 26.5°C) combine with low atmospheric wind shear and high mid-level moisture. Marie's rapid intensification reflects the region's peak tropical cyclone season (September–October) when sea surface temperatures along the Mexican coast remain anomalously warm.
Marie's intensification mechanism stems from three factors: abundant atmospheric moisture transport from the Intertropical Convergence Zone, weak to moderate wind shear allowing the storm's circulation to remain coherent, and warm boundary layer air fueling convective towers. The storm's forward motion and interaction with the Sierra Madre Occidental mountain range will force orographic lifting, concentrating rainfall over high-elevation terrain and triggering flash floods in narrow canyons and arroyos.
Pandita Data's real-time weather simulation ingests satellite infrared brightness temperatures, microwave precipitation estimates (NOAA MRMS), and aircraft reconnaissance data to map cloud-top dynamics and rainfall intensity. Live sea surface temperature overlays reveal the warm-core engine sustaining Marie's circulation, while pressure tendency fields forecast intensification or weakening trends.
Eastern Pacific tropical storms occur annually; approximately 60% reach hurricane strength. Marie's rapid intensification parallels the 2015 and 2016 seasons when multiple storms affected Mexico's Pacific coast with significant precipitation and flash flood damage.
