  • Impact: Increased risk of accidents and hypothermia for those unprepared for the cold.

3. Safety Precautions for Extreme Weather

To stay safe during extreme weather events in Nanjing, follow these guidelines:

a. Heatwaves

  • Stay indoors during peak heat hours (10 AM to 4 PM).
  • Use air conditioning or fans to stay cool. Public cooling centers may be available.
  • Drink plenty of water and avoid alcohol or caffeine, which can dehydrate you.
  • Wear lightweight, loose-fitting clothing and use sunscreen.

b. Typhoons and Heavy Rain

  • Monitor weather updates from reliable sources like the China Meteorological Administration (CMA) or local news.
  • Avoid low-lying areas prone to flooding, such as riverbanks and underpasses.
  • Stock up on essentials like water, non-perishable food, and flashlights in case of power outages.
  • Stay indoors and away from windows during strong winds.

c. Flooding

  • Avoid walking or driving through flooded areas, as water may be deeper than it appears and can hide hazards like open manholes.
  • If you live in a flood-prone area, prepare an emergency kit and know the nearest evacuation routes.
  • Be cautious of waterborne diseases after flooding. Boil water before drinking if the water supply is compromised.

d. Thunderstorms

  • Stay indoors and avoid using electrical appliances during lightning storms.
  • If outdoors, avoid open fields, tall trees, and metal objects.
  • Secure loose items on balconies or rooftops to prevent them from becoming projectiles.

e. Cold Snaps and Icy Conditions

  • Dress in layers and wear insulated, waterproof footwear to prevent slipping on icy surfaces.
  • Use caution when driving or walking on icy roads.
  • Ensure your home is properly heated and insulated.

4. Local Emergency Procedures and Resources

Nanjing has a well-organized emergency response system to handle extreme weather events. Here are some key resources and procedures:

  • Emergency Hotlines:
    • Police: 110
    • Fire: 119
    • Ambulance: 120
  • Weather Updates:
    • The China Meteorological Administration (CMA) provides real-time weather alerts via its website and mobile app.
    • Local TV and radio stations also broadcast weather warnings.
  • Evacuation Centers:
    • In case of severe flooding or typhoons, local authorities may set up temporary shelters. These are usually located in schools, community centers, or government buildings.
  • Transportation Disruptions:
    • During extreme weather, public transportation (buses, subways) may be delayed or suspended. Check the Nanjing Metro app or local news for updates.

5. Associated Costs

  • Cooling Costs: Air conditioning is essential during heatwaves, and electricity bills may increase significantly in summer. Expect to pay around 0.5โ€“0.6 RMB per kWh for residential electricity.
  • Flood Insurance: If you are a long-term resident, consider purchasing flood insurance for your home. Costs vary depending on the coverage.
  • Emergency Supplies: Stocking up on essentials like bottled water, non-perishable food, and flashlights may cost around 200โ€“500 RMB.
  • Winter Heating: Nanjing does not have centralized heating like northern Chinese cities, so you may need to invest in space heaters, which can cost 200โ€“1,000 RMB.

6. Cultural and Procedural Considerations

  • Community Support: In times of extreme weather, neighbors and local communities often come together to help each other. Donโ€™t hesitate to ask for assistance or offer help if needed.
  • Language Barrier: Emergency announcements and resources are often in Mandarin. If you donโ€™t speak the language, consider using translation apps or asking bilingual friends for help.
  • Adaptation for Immigrants: If youโ€™re new to Nanjing, familiarize yourself with local weather patterns and emergency procedures. Joining expat groups or online forums can provide valuable insights and support.
  • Public Behavior: During extreme weather, itโ€™s common for people to stay indoors. Businesses and schools may close temporarily, so plan accordingly.

7. Final Tips for Visitors and Immigrants

  • Always check the weather forecast before planning outdoor activities.
  • Download weather and emergency apps like the CMA app or WeChat for real-time updates.
  • Keep a small emergency kit at home, including a flashlight, batteries, first aid supplies, and bottled water.
  • If youโ€™re visiting during summer or typhoon season, consider travel insurance that covers weather-related disruptions.
