in summer, what happens to the hurricane’s temperature, category, and speed as it travels across a body of water and then land?
IRISSAK [1]

I think it starts to get slower as soon as it starts traveling because then hurricanes wouldnt be as bad and would be long, and it could possible get worse as it travels across the water because it could be sucking up water so then it would get bigger and worse. The tempertaure will get colder because it will then start to pour and cause destruction and make it windy and very chilly.
