Based on track data, Guchol is expected to remain approximately 429 km from Tokyo, with minimal direct threats currently anticipated.
Based on track data, Guchol is expected to remain approximately 524 km from Naha (Okinawa), with minimal direct threats currently anticipated.
Based on track data, Guchol is expected to remain approximately 598 km from Osaka, with minimal direct threats currently anticipated.
Projected rainfall totals of approximately 50-150 mm (2-6 inches) may occur in affected areas, creating risks of flash flooding and urban flooding.
Yes. Tropical systems carry abundant moisture, and outer rainbands can trigger flash flooding, river flooding, and urban flooding.
Adjust preparations based on the storm category and official advice. Secure outdoor items, prepare emergency supplies, keep backup power available, and follow official advisories.
Evacuation decisions must strictly follow official directives issued by local emergency management agencies. If an evacuation order is issued, evacuate immediately using designated routes. Do not rely solely on a single forecast model.
StormAtlas regularly updates based on publicly available data from international meteorological agencies. The latest data update was at August 12, 2026 at 08:08 PM.
Guchol developed over warm ocean waters under conditions of high atmospheric moisture and low vertical wind shear.
The forecast path integrates data from multiple international meteorological agencies and numerical weather prediction models (such as NHC, JMA, JTWC, and CMA) using ensemble forecasting methods to generate probabilistic forecast tracks.

Typhoon Guchol (2023): A Retrospective Analysis
Formation and Meteorological History
Typhoon Guchol, known in the Philippines as Egay, was a powerful tropical cyclone that formed in the Western Pacific in June 2023. The system originated from a tropical disturbance east of the Philippines on June 6. It gradually organized, becoming a tropical depression on June 7 and a tropical storm on June 8, receiving the name Guchol. The storm intensified rapidly under favorable conditions, reaching typhoon status on June 9. Guchol peaked as a Category 4-equivalent typhoon on the Saffir-Simpson scale, with 1-minute sustained winds of 115 knots (215 km/h) according to the Joint Typhoon Warning Center (JTWC). The Japan Meteorological Agency (JMA) assessed 10-minute sustained winds of 175 km/h. Guchol was the first Category 4 typhoon in the Western Pacific in June since 2012. It tracked northwestward, passing near the Okinawa Islands before recurving northeastward and transitioning into an extratropical cyclone on June 12.
Impact and Damages
Philippines: Guchol enhanced the southwest monsoon, bringing heavy rains to Luzon and the Visayas. Flooding and landslides affected several provinces, displacing thousands. Agricultural damage was significant, with rice and corn crops destroyed. Total damage in the Philippines was estimated at PHP 1.2 billion (USD 22 million). No direct fatalities were reported, but the storm contributed to monsoon-related deaths.
Japan: The storm passed near the Okinawa Islands, bringing strong winds and heavy rain. Power outages affected thousands of households. One fatality was reported due to a landslide in Okinawa. Agricultural damage in Okinawa Prefecture was estimated at JPY 3 billion (USD 21 million).
Taiwan: Guchol's outer bands brought heavy rainfall to northern Taiwan, causing localized flooding and minor landslides. No fatalities were reported.
China: The storm's remnants brought rain to eastern China, but impacts were minimal.
South Korea: Guchol's extratropical remnants brought gusty winds and rain to Jeju Island and the southern coast, causing minor damage.
Government Response and Relief Efforts
Philippines: The National Disaster Risk Reduction and Management Council (NDRRMC) pre-positioned relief supplies and conducted evacuations. The Department of Social Welfare and Development (DSWD) provided food packs and financial assistance. The Philippine Coast Guard suspended sea travel in affected areas.
Japan: The Japan Meteorological Agency issued warnings for heavy rain and strong winds. The Okinawa Prefectural Government activated emergency response teams. The Self-Defense Forces were deployed for rescue operations.
Taiwan: The Central Weather Bureau issued heavy rain advisories. Local governments set up emergency response centers.
International: The ASEAN Coordinating Centre for Humanitarian Assistance offered support, but no major international aid was required.
