Cold Snap Is Short But Sharp

  • The coldest nights will hit -2°C tonight and possibly -3 to -4°C tomorrow night before warming on Friday.
ADVICE

Defrost Safely, Don’t Rush Out

  • Detach stuck wipers and let the car warm and demist before driving to avoid burning motors or breaking blades.
  • Use lukewarm water if needed and avoid boiling water to prevent cracking the windscreen.
ADVICE

Clear All Windows Before You Drive

  • Clear the entire driver's and passenger's windows before pulling out so you can see clearly from side roads.
  • Avoid lowering electric windows in cold weather to prevent snapped regulators and seized motors.
