They are both low pressure systems. All hurricanes start as thunderstorms, but gain energy from traveling over warm water.

2. The Atlantic hurricane season is officially from 1 June to 30 November. There is nothing magical in these dates, and hurricanes have occurred outside of these six months, but these dates were selected to encompass over 97% of tropical activity. June 1st has been the traditional start of the Atlantic hurricane season for decades. However, the end date has been slowly shifted outward, from October 31st to November 15th until its current date of November 30th. During an average year there are 9.4 named storms, 5.8 hurricanes, and 2.5 intense hurricanes (cat 3 or higher).

3. Answered above.

4. If the storm come out of the Pacific it is a typhoon. If it comes out of the Indian Ocean in is a tropical cyclone.

5. Category One Hurricane: Winds 74-95 mph (64-82 kt or 119-153 km/hr). Storm surge generally 4-5 ft above normal. No real damage to building structures. Damage primarily to unanchored mobile homes, shrubbery, and trees. Some damage to poorly constructed signs. Also, some coastal road flooding and minor pier damage.
-Category Two Hurricane: Winds 96-110 mph (83-95 kt or 154-177 km/hr). Storm surge generally 6-8 feet above normal. Some roofing material, door, and window damage of buildings. Considerable damage to shrubbery and trees with some trees blown down. Considerable damage to mobile homes, poorly constructed signs, and piers. Coastal and low-lying escape routes flood 2-4 hours before arrival of the hurricane center. Small craft in unprotected anchorages break moorings.
-Category Three Hurricane: Winds 111-130 mph (96-113 kt or 178-209 km/hr). Storm surge generally 9-12 ft above normal. Some structural damage to small residences and utility buildings with a minor amount of curtainwall failures. Damage to shrubbery and trees with foliage blown off trees and large trees blown down. Mobile homes and poorly constructed signs are destroyed. Low-lying escape routes are cut by rising water 3-5 hours before arrival of the center of the hurricane. Flooding near the coast destroys smaller structures with larger structures damaged by battering from floating debris. Terrain continuously lower than 5 ft above mean sea level may be flooded inland 8 miles (13 km) or more. Evacuation of low-lying residences with several blocks of the shoreline may be required.
-Category Four Hurricane: Winds 131-155 mph (114-135 kt or 210-249 km/hr). Storm surge generally 13-18 ft above normal. More extensive curtainwall failures with some complete roof structure failures on small residences. Shrubs, trees, and all signs are blown down. Complete destruction of mobile homes. Extensive damage to doors and windows. Low-lying escape routes may be cut by rising water 3-5 hours before arrival of the center of the hurricane. Major damage to lower floors of structures near the shore. Terrain lower than 10 ft above sea level may be flooded requiring massive evacuation of residential areas as far inland as 6 miles (10 km).
-Category Five Hurricane: Winds greater than 155 mph (135 kt or 249 km/hr). Storm surge generally greater than 18 ft above normal. Complete roof failure on many residences and industrial buildings. Some complete building failures with small utility buildings blown over or away. All shrubs, trees, and signs blown down. Complete destruction of mobile homes. Severe and extensive window and door damage. Low-lying escape routes are cut by rising water 3-5 hours before arrival of the center of the hurricane. Major damage to lower floors of all structures located less than 15 ft above sea level and within 500 yards of the shoreline. Massive evacuation of residential areas on low ground within 5-10 miles (8-16 km) of the shoreline may be required. Only 3 Category Five Hurricanes have made landfall in the United States since records began.

5. Warning signs are thing like massive dark clouds on the horizon, strong winds and a storm surge. But before it comes to that, the national hurricane center will alert the are of how big the storm is and how strong it will be when it hits. From there local media will help alert the public and emergency agencies will make sure all residents in affected area are aware of the danger and help with evacuations if they are needed.

1) Thunderstorm are the beginning stages of the hurricane, as more moist air from the 80 or more from the oceans, it continues to grow into higher towering clouds, soon they begin to become a spiral and the Tropical Depression is born, once it becaomes higher than 35 mph, it becomes a Tropical Storm and given a name, once it reaches 75 or more, it becomes a Catagory 1 hurricane, there are five catogories in the hurricane.
2) Hurricane season in the Atlantic runs from June 1 to October 31
3) The warm ocean which is 80 degrees or higher is the soruce for the fuel for hurricanes
4) In the Eastern Pacific and Atlantic they are called hurricanes, in the Western Pacific they are called Typhoons, and is the Indian Ocean area, they are called Cyclones
5) Winds are one of the biggest problems in the hurricane, the right side of the approaching hurricane winds are stronger than the left side, rain is second, but the most destructive force of the hurricane is the Storm Surge.
6) One of the biggest warning signs is a rapidly falling barometer, the best way to keep informed is many, The Weather Channel has a tropical Storm update every hour, your local news source and the ever available Weather Radio.
