Why is Hurricane Sandy called Frankenstein?

Hurricane Sandy is not called Frankenstein. It is not common to give hurricanes nicknames other than their assigned names.

The name "Frankenstein" is associated with the famous fictional monster created by Mary Shelley in her novel, not with hurricanes.

It's possible you might be thinking of a different storm or a fictional story that uses the name "Frankenstein" in a different context.

To avoid confusion, it's important to stick to the official names given to hurricanes by meteorological organizations.
