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.

∙ 6y agoThe primary reason for the loss of wind speed is that the hurricane has been cut off from its power supply: the heat provided by the convection of water at its core. While it's over warm water, the storm can continue to replenish itself; but as soon as it hits cooler water or dry land, things start to fall apart.
The center of circulation weakens, and pretty soon all you have left is a regular rainstorm: what meteorologists call a remnant low. That tropical remnant can travel hundreds or thousands of miles in just a few days, until it runs out of energy (usually in the high northern latitudes) and disperses completely.
Hurricanes die over land because they depend on evaporation from warm ocean water to maintain their strength. When they move over land they are cut off from this energy source.

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.
Does a tornado or hurricane grow weaker over land?
Hurricanes weaken rapidly over land.
Does Nebraska have hurricanes?
No. Hurricanes only occur over warm ocean water and weaken quickly once they hit land. So Nebraska is too far inland to get hurricanes. It does, however, get plenty of tornadoes.
Does Montana have hurricanes?
No, hurricanes can only form over warm ocean water and they weaken quickly when they hit land. Montana is too far inland to get hurricanes. However, other types of storm can still produce hurricane force winds.
When Has the state of Kansas ever had a hurricane?
No. Hurricanes only form over tropical ocean water and weaken rapidly if they hit land. Kansas is too far inland to get hurricanes. The state does, however, get plenty of tornadoes.
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.
Can a funnel cloud weaken?
Yes, all weather patterns will weaken and dissipate eventually.
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.
What weakens over land hurricanes or tornadoes?
Hurricanes weaken when they move over land.
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.
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.
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.
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.
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.
