Typhoon Co: Shanghai Faces Potential Landfall Between Pudong and Fengxian

here’s a breakdown of the details from the provided text:

Typhoon Co-may:

Current Status: Churning over the East China Sea, gaining strength, currently at tropical storm intensity.
Movement: Moving northwest at 10-15 kilometers per hour.
Projected Landfall:
First Landfall: wednesday, along the Zhejiang coast between Zhoushan and Ningbo.
second Landfall: Later on Wednesday (evening/night), along the coast of Shanghai, specifically between Fengxian District and the southern part of Pudong New Area.
Expected Impacts on Shanghai:
Rainfall: Heavy rain starting late Tuesday, substantially increasing in intensity and coverage through Wednesday morning. Heaviest rainfall expected from Tuesday night through Wednesday daytime. Total precipitation could reach heavy rainfall levels, wiht localized areas experiencing torrential rain (perhaps 200-220 mm).
Wind: Land-based gusts expected to peak at levels 7-8. Stronger winds (9-10) likely along the Yangtze River and coastal areas. Offshore areas like Yangshan Port could experience the strongest gusts (10-11).
Temperature & Humidity:
Tuesday: Around 31°C, hot and humid.
Wednesday: Daytime highs around 26-28°C due to wind and rain, but still uncomfortable due to low atmospheric pressure and high humidity.
Lingering effects: Expected to weaken gradually but remain over eastern China through the end of the week, bringing intermittent showers to Shanghai until around Saturday.
Return to Normal: Dry and sunny conditions are forecast to return next week as a subtropical high-pressure system rebuilds.

Emergency Response:

Level IV Emergency Response: Issued for Shanghai, Zhejiang, and Jiangsu provinces on Monday.
Government Support: A work group has been dispatched to Zhejiang to assist with flood and wind damage management.

Advice to Residents:

Take precautions.
Stay updated through official weather bulletins.
Avoid unneeded outdoor activities during the storm’s peak.

Overall Threat: The threat of flooding and disruption remains meaningful due to the dual landfall and lingering presence of Typhoon Co-may.

What specific actions should residents in Pudong and Fengxian Districts take to secure their homes ahead of Typhoon Co’s landfall?

Current Status & Forecast Track

As of 08:00 CST, July 29, 2025, Typhoon Co is rapidly approaching the Shanghai coastline. The Central Meteorological Observatory of China has issued an orange warning for the typhoon, indicating a high degree of threat. current projections suggest a potential landfall between Pudong New Area and Fengxian District within the next 12-18 hours. The storm is currently packing sustained winds of 150 km/h (93 mph) with gusts up to 190 km/h (118 mph). its trajectory is influenced by a subtropical high-pressure system,making precise landfall location predictions challenging,but the core threat remains focused on the southeastern Shanghai region. This is a meaningful tropical cyclone event.

Understanding the Threat: Typhoon vs. Hurricane vs. Tornado

It’s crucial to understand the terminology. While frequently enough used interchangeably, typhoons, hurricanes, and tornadoes are distinct weather phenomena.

Typhoon: A mature tropical cyclone that develops in the northwestern Pacific Ocean. This is what Shanghai is currently facing.

Hurricane: A mature tropical cyclone that develops in the Atlantic Ocean or the northeastern Pacific Ocean.

Tornado: A violently rotating column of air extending from a thunderstorm to the ground.

The key difference lies in their formation and location. Typhoons and hurricanes are large-scale weather systems, while tornadoes are much smaller and localized. The impact of a typhoon can be widespread, affecting entire coastal regions.

Impact Zones: Pudong & Fengxian Districts

The areas most at risk are Pudong New Area,particularly the coastal regions of Nanhui and Lingang,and Fengxian District,including the areas around Haiwan Town and Nanxiang.

Pudong: High-rise buildings in Pudong’s Lujiazui financial district, while structurally sound, are susceptible to wind damage and power outages.The extensive port facilities are at risk of disruption.

Fengxian: Lower-lying areas of Fengxian are particularly vulnerable to storm surges and flooding. Agricultural lands in the district could experience significant damage.

Beyond these primary zones, neighboring districts like Jinshan and Chongming Island are also under alert for potential impacts, including heavy rainfall and strong winds. Shanghai weather authorities are closely monitoring the situation.

Potential Hazards & risks

Typhoon Co poses a multitude of hazards:

1. Strong Winds: Capable of causing structural damage to buildings,uprooting trees,and disrupting transportation.
2. Heavy Rainfall: Expected to exceed 200mm (8 inches) in some areas, leading to widespread flooding.
3. Storm Surge: A significant threat, particularly along the coastline. A storm surge of 2-3 meters (6.5-10 feet) is possible, potentially inundating low-lying coastal areas.
4. Power Outages: Widespread and prolonged power outages are highly likely due to downed power lines.
5. Transportation Disruptions: Flights, trains, and ferry services are already being cancelled or delayed. Road travel will become increasingly perilous.

Preparedness Measures: What Shanghai Residents Should Do

Shanghai authorities have implemented several preparedness measures, including:

Evacuations: Mandatory evacuations are underway in vulnerable coastal areas.

Shelter Activation: Emergency shelters have been opened to accommodate evacuees.

Infrastructure Protection: Efforts are being made to secure critical infrastructure,such as power plants and water treatment facilities.

Public Transportation Suspension: Metro lines and bus routes in affected areas are being suspended.

For residents, the following steps are crucial:

stay Informed: Monitor official weather updates from the Shanghai Meteorological Bureau and local news sources.

Secure Your Home: Reinforce windows and doors, bring loose objects indoors, and disconnect electrical appliances.

Prepare an Emergency Kit: Include essential supplies such as food, water, medication, a flashlight, and a first-aid kit.

Follow Evacuation Orders: If you are in an evacuation zone, evacuate immediately.

Avoid Travel: Stay off the roads and avoid unnecessary travel.

Historical Context: Shanghai & Typhoons

Shanghai has a history of being impacted by typhoons. In 2015, Typhoon dujuan brought strong winds and heavy rainfall to the city, causing significant disruptions. More recently, Typhoon In-fa in 2021 caused widespread flooding and
