Hurricanes depend on a continuous supply of moisture from warm ocean water to maintain themselves. If the storm moves over land or cold water it loses this fuel source and weakens. This can also happens of the hurricane moves into a mass of dry air. Additionally, if a hurricane encounters strong wind shear it can be essentially ripped apart.

Detailed Answer:

A tropical cyclone can cease to have tropical characteristics through several different ways. One such way is if it moves over land, thus depriving it of the warm water it needs to power itself, quickly losing strength. Most strong storms lose their strength very rapidly after landfall and become disorganized areas of low pressure within a day or two, or evolve into extratropical cyclones. While there is a chance a tropical cyclone could regenerate if it managed to get back over open warm water, if it remains over mountains for even a short time, weakening will accelerate. Many storm fatalities occur in mountainous terrain, as the dying storm unleashes torrential rainfall, leading to deadly floods and mudslides, similar to those that happened with Hurricane Mitch in 1998. additionally, dissipation can occur if a storm remains in the same area of ocean for too long, mixing the upper 60 metres (200 ft) of water, dropping sea surface temperatures more than 5 °C (9 °F). Without warm surface water, the storm cannot survive.

When do hurricanes weaken?

Hurricanes weaken either when they move over land or colder water.


How do hurricanes dissipate?

Hurricanes dissipate due to lack of water supply, cold water and stalling. There must be movement for the storm to be a hurricane.


Can a funnel cloud weaken?

Yes, all weather patterns will weaken and dissipate eventually.


Can a hurricane die down becasue its too cold?

Yes. Hurricanes depend on warm, moist air to maintain their strength. A hurricane that enters a cold environment will usually weaken and dissipate.


Do hurricane occur in water?

Hurricanes FORM over water. They also gain their intensity over water. When a hurricane comes in over land, it of course causes the most destruction to man-made Objects. However, when over land Hurricanes generally weaken or dissipate.


Do hurricanes strengthen as they pass over land?

No. Hurricanes weaken as they pas over land.


What weakens over land hurricanes or tornadoes?

Hurricanes weaken when they move over land.


Where and why did hurricane ike dissipate?

Hurricanes dissipate when they reach land because there is no water to strengthen them. Hurricane Ike began to dissipate as soon as it hit land and it dissipated in eastern Canada.


What is the synonym of evaporate?

Disappear, Disperse, dissipate, fade, melt, vanish, vaporize, weaken.


Do any hurricanes happen in Colorado?

No. Colorado is smack in the middle of the US. Hurricanes feed off of water and dissipate quickly on land.


Why will hurricane earl weaken when over land?

Hurricanes are fueled by water.


Why do hurricanes weaken at shore?

There is no more water to feed the hurricane, therefore it slowly dies out. That is why there are not hurricanes in Kansas per say.


How do hurricanes weaken and decay?

When they go over cold water or hit land


Does Tennessee get hurricanes?

No. Hurricanes can only form over warm ocean water and weaken when they hit land. Tennessee can get hurricane remnants, but is too far inland to get actual hurricanes.


Hurricanes and tornadoes how long does it take to travel over land?

The average tornado lasts about 10 minutes, but durations may range anywhere from just a few seconds to over three hours. Hurricanes usually last several days, and can last as long as a month, however hurricanes spend nearly all of their time over open ocean, not land. A hurricane will weaken rapidly and dissipate if it moves over land.


Do hurricanes weaken because there winds are counteracted by the land and sea breezes?

No, hurricanes are fueled by warm ocean water so they weaken because they lose the warm ocean water on land. A hurricane controls the sea ocean breezes.


Are there hurricanes in Vermont?

Not really- If a storm that used to be a hurricane hits Vermont it usually is a Tropical Storm or Depression- hurricanes weaken over land


What happens to hurricanes when they were in land and then went to the ocean?

Hurricanes that strike land weaken rapidly. If they re-emerge onto water they have the opportunity to restrengthen.


What do hurricanes need to become stronger?

Warm (hot) water plus winds aloft that do not dissipate their energy.


Do hurricanes form on land?

No, they form over water and weaken or die if they hit land.


How do hurricanes and tornadoes stop?

Hurricanes usually dissipate when they are cut off from the warm ocean water that fuels them through evaporation. This usually happens when the storm moves over land or colder water. Wind shear can also greatly weaken a hurricane. How tornadoes dissipate is not fully understood, but it is believed that outflow from a thunderstorm (either the one that produced the tornado or a separate storm) wraps around the parent circulation (mesocyclone) of the tornado, and essentially choking off the supply of warm air that drives the updraft.


Has every us state had a hurricane storm?

No. Hurricanes rapidly weaken after hitting land, so only the coastal states have experienced actual hurricanes.


Why do hurricanes not happen in Kansas?

Hurricanes only form over warm ocean water and begin to weaken and degenerate as soon as they hit land. Kansas is too far inland for hurricanes to reach it.


Can hurricanes occur on dry land?

Not really. Hurricanes can only form over warm ocean water. Once they hit land they weaken rapidly and don't stay as hurricanes for very long.


Do hurricanes always hit land?

No. It is not uncommon for a hurricane to develop and dissipate at seas without ever hitting land.
