Tropical cyclones frequently produce huge amounts of rain , and flooding can be a significant problem, particularly for inland communities. A typical hurricane brings at least 6 to 12 inches of rainfall to the area it crosses. The resulting floods cause considerable damage and loss of life. The heaviest rain usually occurs near or along the cyclone track in the period 6 hours before and 6 hours after landfall. However, storms can last for days.
Tornadoes spawned by landfalling hurricanes can cause enormous destruction.
As a hurricane moves shoreward, tornadoes often develop on the fringes of the storm. When associated with hurricanes, tornadoes are not usually accompanied by hail or a lot of lightning, clues that citizens in other parts of the country watch for. Tornado production can occur for days after landfall when the tropical cyclone remnants maintain an identifiable low pressure circulation. They can also develop at any time of the day or night during landfall. However, by 12 hours after landfall, tornadoes tend to occur mainly during daytime hours.
