What is a hurricane, exactly?
A hurricane is a large rotating storm that forms over tropical or subtropical waters in the Atlantic. These low pressure weather systems draw upon warm water and atmospheric moisture to fuel their strength and will gather pace if not slowed by patches of dry air, crosswinds or landfall.
“They are very tall towers of winds that move at the same speed, sometimes 60,000ft tall,” says Jim Kossin, a scientist at the US National Oceanic and Atmospheric Administration. “If they are unmolested by wind shear or run over land they will continue on their merry way.”
