Typhoon Dolphin Evacuations: Record Rainfall Hits Shanghai 2026

Typhoon Dolphin triggered more than a million evacuations across eastern China, as record rainfall pounded Shanghai and raised alarms over flooding and landslides. The storm’s intensity and unprecedented precipitation highlight the growing impact of climate change on coastal megacities.

Typhoon Dolphin’s Impact on Eastern China

By Sunday evening, over one million people had been moved to safety across Zhejiang, Fujian, and Shanghai. Wenzhou alone relocated more than 900,000 residents, opening over 1,500 emergency shelters. In Shanghai, 215,600 people were evacuated from high-risk zones, a dramatic increase from the earlier figure of 30,300.

The storm made landfall as a powerful typhoon but weakened rapidly to a tropical storm by Monday morning. However, forecasters warned of continued heavy rainfall across eastern and central China, with some areas expecting 200–400mm (7.9–15.7 inches) of rain over the coming days.

Record Rainfall in Shanghai

A weather station in Shanghai’s city center recorded its highest 24-hour rainfall in more than 150 years. This historic downpour led to widespread flooding, forcing the cancellation of over 1,300 flights at the city’s two airports. Authorities urged residents to stay indoors as intense rain was forecast through Wednesday.

The storm’s path also affected neighboring provinces, including Henan, Hubei, Anhui, Jiangsu, and Zhejiang, where landslide and flood risks remained high. In Japan’s Okinawa prefecture, Typhoon Dolphin injured six people and cut power to more than 50,000 buildings before moving toward China.

Comparison: Typhoon Dolphin vs. Past Typhoons

Key Takeaways for Disaster Preparedness

• Early evacuation saves lives – over 900,000 people moved in Wenzhou alone.
• Record rainfall underscores the need for upgraded urban drainage systems.
• Air travel disruption is inevitable; airlines cancelled 1,300+ flights in Shanghai.
• Climate change amplifies typhoon intensity and rainfall, requiring adaptive planning.

Global Warming and Extreme Weather

Scientists link global warming to more powerful typhoons and extreme rainfall events. Warmer air holds more moisture, leading to heavier downpours and increased flood risk. As Typhoon Dolphin demonstrated, even well-prepared cities like Shanghai face unprecedented challenges.

In the Philippines, the typhoon intensified seasonal monsoon rains, flooding large areas of Luzon, including Manila. This regional impact shows that typhoon effects extend beyond landfall, affecting weather patterns across Southeast Asia.
