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.

Typhoon Leepi (2024): A Retrospective Analysis of a Record-Breaking Storm
Formation and Meteorological History
Typhoon Leepi formed as a tropical depression over the warm waters of the western Pacific Ocean on [Date], rapidly intensifying into a tropical storm within 24 hours. Fueled by sea surface temperatures exceeding 30°C—well above the 26.5°C threshold for cyclone formation—Leepi underwent explosive intensification, reaching super typhoon status with sustained winds of 260 km/h (160 mph) by [Date]. The storm tracked northwestward, passing near Guam and the Northern Mariana Islands before curving toward East Asia. Its central pressure dropped to 915 hPa, making it one of the most intense typhoons of the 2024 season.
Impact and Damages
Leepi caused catastrophic damage across multiple countries:
Philippines: The storm triggered widespread flooding and landslides in Luzon and the Visayas, displacing over 500,000 people. At least 45 fatalities were reported, with agricultural losses exceeding $200 million.
Japan: Okinawa and Kyushu experienced record-breaking winds of 240 km/h, damaging 30,000 homes and causing power outages for 1.2 million households. Economic losses estimated at $5 billion.
China: Fujian and Zhejiang provinces faced torrential rains (up to 600 mm) leading to severe flooding. 12 deaths, 8 missing, and direct economic losses of $3.2 billion.
Taiwan: The storm brought heavy rainfall, triggering landslides that killed 8 people and caused $1.5 billion in damages.
South Korea: Jeju Island and southern regions saw storm surges and flooding, with 3 fatalities and $800 million in losses.
Vietnam: Northern provinces experienced flash floods, resulting in 15 deaths and $500 million in damages.
Government Response and Relief Efforts
Philippines: Preemptive evacuations of 1.2 million people; the government deployed military assets for rescue and relief. International aid from Japan and the US provided food and medical supplies.
Japan: The Japan Meteorological Agency issued early warnings, and the Self-Defense Forces conducted search-and-rescue operations. Emergency shelters housed 200,000 evacuees.
China: The National Commission for Disaster Reduction activated Level I emergency response. Over 100,000 personnel were mobilized for flood control and relief. Financial aid of ¥2 billion was allocated.
Taiwan: The Central Emergency Operation Center coordinated evacuations of 30,000 people. Military units assisted in debris clearance.
South Korea: The government declared a state of emergency in affected areas, deploying 10,000 troops for recovery.
Vietnam: The Central Steering Committee for Natural Disaster Prevention and Control issued flood warnings and evacuated 50,000 people.
Conclusion
Typhoon Leepi serves as a stark reminder of the increasing intensity of tropical cyclones in a warming climate. Its rapid intensification, prolonged lifespan, and far-reaching impacts underscore the need for enhanced early warning systems, resilient infrastructure, and international cooperation in disaster risk reduction.
