Heatwave

Understanding the risk

The highest temperature recorded in Cannes was 39.2°C on 19 July 2023.

Prepare your 72-hour emergency kit

The 72-Hour Emergency Kit

Power cuts, disruptions to gas and running water supplies, impassable roads… when a major disaster strikes, the first 72 hours are often the most challenging. Preparing this kit in advance will help you stay at home with greater peace of mind while waiting for help to arrive. It will also be invaluable if you need to leave at short notice.

Here is what to include in your kit:

  • a battery-powered radio (with spare batteries) to follow instructions from the authorities
  • medications
  • a first aid kit (antiseptic, plasters, sterile dressings…)
  • basic tools (a multi-tool, tin opener…)
  • non-perishable food that requires no cooking (tinned food, jars of baby food, pet food…)
  • warm clothing and an emergency blanket
  • a torch (with spare batteries), candles, a lighter or matches
  • a mobile phone charger
  • a spare pair of prescription glasses
  • cash (cash machines may be out of service)
  • plenty of bottled drinking water (6 litres per person)
  • photocopies of essential documents in a waterproof pouch (identity card, prescriptions…)
  • spare house and car keys
  • games to pass the time.

Keep the bag somewhere easily accessible.
Check the contents of your kit once a year, particularly the expiry dates of medication and food. Replace the batteries too.

Remember to replenish your kit after use!
