Sewerage lines were cut, resulting in a lack of sanitation, and poisons therefore leached out … into the environment, which affected living organisms. In fact, these strong winds tend to affect the other destructive agents of cyclones. Communication systems are badly affected due to cyclones. Potentially disastrous surges occur along coasts with low-lying terrain that allows inland inundation, or across inland water bodies such as bays, estuaries, lakes, and rivers leading to severe flooding. The wet environment in the aftermath of a tropical cyclone, combined with the destruction of sanitation facilities and a warm tropical climate, can induce epidemics of disease which claim lives long after the storm passes. Surge is maximum in the right forward sector of the cyclone and about 50-100 Km from the centre coinciding with the zone of maximum wind.
The resultant animal deaths can break the food chain causing more animals to die. The leading explanations for regional differences in mortality is the size of the at risk population and the capacity for pre-event evacuation. This will cause the water at first to be blown away from the coast then as the centre of the cyclone passes by and the wind drops down, the water slashes back that may be accompanied by wind in similar direction. Houses, roads, sewage pipes and power lines all need to be rebuilt. Mariners have a way to safely navigate around tropical cyclones.

Category 5 storms are the most forceful, bringing winds of more than 156 miles per hour. A significant factor in the growing losses caused by meteorological hazards is the concentration of population and economic activity in coastal plains and low-lying areas that are subject to storm surges and land-borne flooding. Monitoring poison control center data to detect health hazards during hurricane season--Florida, 2003-2005.
