Sydney weather: Woman, 31, is killed in car crash as storm strikes ...

A woman has died in a car crash during wild weather that saw four people struck by lightning, caused major delays at Sydney Airport and sparked commuter chaos.

The 31-year-old woman died after her SUV collided with another in Narrabeen on Sydney's Northern Beaches.

The crash took place after torrential rain hit the city, with a fierce storm tearing a hole in the main runway at the airport. 

The damage caused flights to be cancelled as well as sparking a series of delays.

Meanwhile four people who were sheltering from the rain under trees in the Royal Botanic Garden were struck by lightning.
