⛈️ OPEN LIVE 3D WEATHER ALERTSMay 27, 2026 — A severe tropical cyclone system designated Jangmi is intensifying across the Western Pacific, with Japan's southernmost prefectures now in the direct impact zone. The storm, positioned at 12.7°N, 135.9°E, is generating sustained winds exceeding 100 km/h and producing torrential rainfall across Okinawa, Kyushu, and extending northward. Japan Meteorological Agency (JMA) forecasts storm surge heights of 1.5–2.5 metres above normal tide levels, with flash flooding probable across steep volcanic terrain.
Typhoon Jangmi's rapid intensification results from warm Western Pacific sea-surface temperatures (currently 29–30°C) combined with low wind shear at mid-tropospheric levels. This configuration permits the Coriolis effect to organize convection into a coherent circulation, drawing latent heat energy from the ocean and converting it into rotational kinetic energy. Japan's position at 30–35°N places it directly in the storm's projected steering current, driven by subtropical high-pressure systems and mid-latitude westerlies.
Pandita's live weather simulation ingests near-real-time NOAA satellite imagery, wind-field analysis, and JMA tracking data to model cloud motion, precipitation distribution, and sea-level anomaly. Geostationary satellite bands track convective cloud-top temperatures, while surface wind analysis from ASCAT scatterometer constrains the actual circulation. Users can rotate the 3D model to visualize the storm's vertical structure and track the storm-surge propagation vector.
Japan experiences 1–2 direct typhoon impacts per year. Peak season is August–October, though May–June events occur during anomalous seasons. Storm surge is the leading cause of coastal fatalities; rainfall-triggered landslides dominate inland casualties in mountainous prefectures like Nagano and Gifu.
Watch Pandita's live 3D weather simulation to track Jangmi's approach and understand how orographic effects will amplify rainfall across Japan's western highlands.
FAQ::[ { "q": "What is causing this severe weather?", "a": "Typhoon Jangmi intensifies over warm Western Pacific waters (29–30°C) with minimal wind shear, organizing convection into a powerful tropical cyclone steered toward Japan." }, { "q": "What are the greatest hazards from this storm?", "a": "Storm surge (1.5–2.5 m), extreme rainfall (500+ mm), destructive winds (100+ km/h), and landslides threaten coastal and mountainous areas across Okinawa, Kyushu, and central Honshu." }, { "q": "What precautions should people take immediately?", "a": "Coastal residents: evacuate to high ground or designated shelters now. All residents: stock water/food, charge devices, monitor JMA alerts, and avoid floodwaters and wind exposure." }
