Answer: Storm surge, wind damage, and inland flooding; with storm surge being the most damaging and deadly.
Step-by-step explanation:
Storm surges caused by hurricanes are very damaging and deadly because they can come unexpectedly and send a significant amount of water into areas of human settlements including homes and businesses. When this happens they cause loss of life and property damage.
Following behind them is wind damage which can destroy buildings and landscapes causing millions in property damage. Inland flooding rounds up this list and causes a significant amount of damage as well as trapping people.
