Purdue study uncovers why some hurricanes balloon in size and what that means for forecasting future storms

When people hear about hurricanes, they often focus on the category rating: Category 1 through 5, based on maximum wind speeds. But not all hurricanes with the same wind speeds are alike. Some are compact storms while others can span the size of entire states. Larger hurricanes bring far greater damage, generating wider footprints of high winds, heavier rainfall and more dangerous storm surge.
