Typhoon Dolphin Forces Million-Plus Evacuations Across Eastern China

Torrential rains shatter 150-year Shanghai records as Typhoon Dolphin drives the largest mass evacuation in China's recent storm history.

By Sunday evening, more than one million people had been moved to safety across eastern China as Typhoon Dolphin made landfall, triggering fears of catastrophic flooding and landslides along one of the world's most densely populated coastlines. Wenzhou, a coastal city in Zhejiang province, relocated over 900,000 residents alone and opened more than 1,500 emergency shelters. In neighbouring Fujian province, nearly 99,000 people were evacuated from zones considered at highest risk, while Shanghai — China's financial capital — moved an additional 215,600 residents, a figure that had ballooned from an earlier estimate of just 30,300 as conditions rapidly deteriorated. The rainfall records that fell were particularly striking.

A weather station in central Shanghai recorded close to 313 mm of rain in the 24 hours ending at 7 am on Monday — the highest single-day total in more than 150 years of observations at that site. A second station in the city registered nearly 400 mm. The hashtag "Shanghai turns into the sea" trended on Weibo as videos circulated showing floodwater engulfing streets around the Wukang Mansion, one of the city's most recognisable landmarks. Across Zhejiang as a whole, average rainfall between Friday evening and Monday morning reached 173 mm, reportedly exceeding levels recorded during previous major typhoons, including Lekima and Bavi.

Dolphin weakened to a tropical storm by early Monday, but Chinese forecasters warned that the danger was far from over. Orange-level rain alerts remained in force across six provinces and municipalities stretching north into Shandong, with some areas expected to receive a further 200–400 mm through Wednesday. More than 1,300 flights were cancelled at Shanghai's two airports, and subway and rail services across the region were suspended or severely curtailed.

Discuss
  • Why might Shanghai's 150-year rainfall record matter beyond the immediate emergency?
  • How does the speed of an evacuation decision affect the number of lives saved during a typhoon?
  • What does the rapid expansion of Shanghai's evacuation figure — from 30,300 to 215,600 — suggest about how authorities manage risk information?

England's drought now covers three-quarters of country

When Southern Water applied for emergency orders to draw from the River Test despite critically low flows, it marked a threshold England had not crossed in a generation. Three-quarters of the country is now officially in drought, affecting 27 million people. Reservoir levels have fallen to 69% — nearly 12 points below the seasonal average — while farmers are reporting their earliest harvests in 20 years, with reduced yields. This is England's fifth heatwave of a single summer, with 34 days already reaching 30°C or above.…

Birdwatchers become flu sentinels in Australia

When South Australia confirmed its first H5 avian influenza case near Robe on the Limestone Coast, Jean Turner — a birder on Kangaroo Island, 200 km away — had already seen the warning signs: photographs of dead seal pups along Argentine beaches and rows of lifeless seabirds laid out by researchers in Antarctica. She is now one of more than 120 volunteers in the Bird Observers Network, a partnership between the SA government, Conservation Council SA, and BirdLife Australia that trains citizens to identify and report symptomatic birds. Turner has already flagged a trembling, swaying crested tern — a species since confirmed positive for H5 on Kangaroo Island — raising a quiet question about how many others have gone unnoticed.

Authorities warned that days of intense rain could trigger widespread flooding and landslides through Wednesday, urging people to stay indoors during the heavy downpours.

2GRAMMAR FOCUS
Relative clauses — defining vs non-defining with commas
A defining relative clause identifies which person or thing is meant and uses no commas (e.g. 'the city that was flooded'). A non-defining relative clause adds extra information about something already identified and is separated by commas (e.g.…

  1. Wenzhou is a coastal city relocated over 900,000 residents during Typhoon Dolphin.
  2. Jean Turner, is a birder on Kangaroo Island, flagged a trembling crested tern.
  3. The weather station recorded 313 mm of rain had been operating for over 150 years.
  4. The Wukang Mansion, is one of Shanghai's most recognisable landmarks, appeared in viral flood videos.
  5. Southern Water applied for emergency orders to draw from the River Test, flows had fallen to critically low levels.
  6. Prof Liz Bentley is a scientist research focuses on how climate change accelerates drought.
3IDIOMS
Define each idiom in your own words. Then write one in a sentence of your own.
  1. far from over (Typhoon article: 'the danger was far from over')
  2. in force (Typhoon article: 'Orange-level rain alerts remained in force')
  3. a figure that had ballooned (Typhoon article: 'a figure that had ballooned from an earlier estimate')
  4. warning signs (Bird flu article: 'Jean Turner had already seen the warning signs')
  5. gone unnoticed (Bird flu article: 'how many others have gone unnoticed')
4CRITICAL THINKING
All three stories describe situations where early data was available before the worst occurred — rising typhoon figures, photographs of dead wildlife, and years of recorded heatwaves. What does this pattern suggest about how societies process risk information, and who bears responsibility when warnings exist but large-scale harm still follows?
