Real-time coverage of severeStorms event — Tropical Cyclone Chan-Hom — Pandita Data.
⛈️ OPEN LIVE 3D WEATHER ALERTSTropical Cyclone Chan-Hom intensified over the northwest Pacific Ocean at 32°N, 158.1°E on August 7, 2026, posing significant wind and surge risks to Japan, Korea, and eastern China within 5–7 days. The system is tracking west-northwest at sustained winds exceeding 100 knots, with satellite data showing rapid organization and warm-core structure typical of typhoons in mid-summer conditions.
Communities across southern Japan, the Korean Peninsula, and coastal provinces of China face elevated risk of destructive winds, extreme rainfall exceeding 300mm, and storm surge up to 2–3 meters in exposed bays. Early preparation and evacuation planning are critical; delays during typhoon approach create life-threatening conditions.
Tropical cyclone development requires sea-surface temperatures above 26.5°C, low wind shear, and sufficient atmospheric moisture—all present in the western Pacific in August. Chan-Hom's intensification reflects deep convection driven by latent heat release as warm ocean air rises, condenses, and forms the characteristic eyewall. Upper-level outflow channels energy away, sustaining the low-pressure core.
The Coriolis effect at 32°N (mid-latitude) begins to weaken the cyclone's symmetry, steering it toward higher latitudes and cooler waters. Interaction with the subtropical jet stream will likely cause rapid northeastward recurvature toward Japan by day 5–6.
Real-time NOAA GOES-16 and Japanese Himawari-8 infrared imagery reveal cloud-top temperatures as cold as −80°C in the eyewall, indicating powerful updrafts. Microwave data from SSMIS and AMSR-2 penetrate clouds to measure wind speed, rainfall rate, and moisture content with precision inaccessible to visible cameras alone.
Pandita Data's 3D weather simulation ingests these observations hourly, updating track forecast, intensity, and rainfall distribution. Users can zoom into the eyewall structure and track storm surge risk in real time across vulnerable bays and estuaries.
The region experiences 25–30 typhoons annually; August–October peaks. Storm surge, extreme rainfall, and landslides are primary killers; coastal cities with poor drainage face flash-flood fatalities within hours of landfall.
Monitor Pandita Data's live typhoon simulator for updated track, intensity, and localized wind/rainfall forecasts. National meteorological agencies (JMA, KMA, CMA) issue official warnings; follow evacuation orders without delay.
