What does Bella Swan carry when she leaves Phoenix Arizona for Forks Washington in 'Twilight'?

A parka is Bella Swan's carry-on for the flight from Phoenix, Arizona to Forks, Washington in "Twilight."

Specifically, the weather is sunny, hot and cloudless at the Phoenix airport. But Bella knows that her favorite, sleeveless shirt of white eyelet lace will be no protection against the cool, overcast or rainy weather that will greet her in Forks. Forks receives more rain than any other place in the United States.
