First, the ocean waters must be warm enough at the surface to put enough heat and moisture into the overlying atmosphere to provide the potential fuel for the thermodynamic engine that a hurricane becomes. Second, atmospheric moisture from sea water evaporation must combine with that heat and energy to form the powerful engine needed to propel a hurricane. Third, a wind pattern must be near the ocean surface to spirals air inward.
Hurricanes form over warm ocean waters (typically above 80°F) with enough moisture and instability in the atmosphere. They also require light wind shear (changes in wind direction or speed with altitude) to allow for vertical development of thunderstorms. The Coriolis effect, caused by the Earth's rotation, is necessary for the rotation of a developing storm system into a hurricane.
The birth of a hurricane requires at least three conditions. First, the ocean waters must be warm enough at the surface to put enough heat and moisture into the overlying atmosphere to provide the potential fuel for the thermodynamic engine that a hurricane becomes. Second, atmospheric moisture from sea water evaporation must combine with that heat and energy to form the powerful engine needed to propel a hurricane. Third, a wind pattern must be near the ocean surface to spirals air inward. Bands of thunderstorms form, allowing the air to warm further and rise higher into the atmosphere. If the winds at these higher levels are relatively light, this structure can remain intact and grow stronger: the beginnings of a hurricane!
While rare, it is possible for a tornado to form within a hurricane. These tornadoes, known as "tornadoes embedded in hurricanes," can be particularly dangerous due to the already intense weather conditions from the hurricane.
Hurricane season is when the conditions are most favorable for hurricanes to form, such as warm ocean temperatures and low wind shear. These conditions create the right environment for tropical storms to develop and strengthen into hurricanes. Outside of hurricane season, these conditions are less likely to occur, making hurricanes less common.
Hurricane season in the Atlantic region is primarily influenced by warm ocean temperatures, low wind shear, and high humidity in the atmosphere. These conditions create the ideal environment for hurricanes to form and strengthen.
Hurricanes do not directly form tornadoes. However, tornadoes can sometimes develop within the bands of a hurricane. These tornadoes are typically weaker and shorter-lived compared to those that form in traditional severe thunderstorms. The interaction between the hurricane's circulation and local weather conditions can create the necessary conditions for tornado formation.
No, a hurricane forms over warm ocean waters when conditions are favorable for its development, such as light winds and high humidity. The interaction between hot and cold water alone does not directly lead to the formation of a hurricane.

Same as those anywhere else. See the related question.

No, a hurricane warning is more serious than a hurricane watch. A hurricane watch means that hurricane conditions are possible within the next 48 hours, while a hurricane warning indicates that hurricane conditions are expected within 36 hours. It's important to take immediate precautions when a warning is issued.

Yes. Hurricane Earl produced hurricane conditions in parts of North Carolina and tropical storm conditions in Cape Cod and Long Island.
The three main ingredients for a hurricane are warm ocean water, moist air, and atmospheric instability. These conditions provide the necessary fuel and dynamics for a hurricane to form and strengthen.
When conditions are favorable for tornadoes a tornado watch is issued. However the criteria for a hurricane watch are different. A hurricane watch is issued of an existing storm is threatening an area and hurricane conditions are possible within 48 hours.
