How It forms
The thunderstorm clouds it self is formed by the moisture and unstable air lift. Cool and or dry air flows inward, warm humid air blows up through the freezing level and and into the clouds. Every thunderstorm producces lightning, which kills more people every year than tornadoes do. The lightning is formed by the rising and sinking air, combined with the droplets of water bumping into each other, created electrical chargers, meaning postive or positive propities.
November 9-11, 2002, tornadoes struck 17 states from the Mississippi Valley to the Atlantic Coast and from the Gulf Coast to the Great Lakes. From Saturday afternoon, November 9, to the early morning hours of Monday, November 11, 2002, 76 tornadoes touched down. Twelve of these tornadoes killed 36 people in five states.
During the evening and overnight on January on the 8th and 9th, a line of powerful thunderstorms moved across Kauai and Oahu producing strong wind gusts, wind damage and a small tornado. In fact, this line was identical to systems that usually affect the Central Plains and eastern parts of the mainland during spring and summer. Although relatively rare for Hawaii, such strong to severe thunderstorms do occur, mainly during the winter, when strong cold fronts and jet stream dynamics are most likely to reach as far south as Hawaii.
Severe thunderstorms can cause damage to your house and your self. In the United States, 75 to 100 people are killed each year by lightning, although most lightning victims do survive. People struck by lightning often report a variety of long-term, debilitating symptoms, including memory loss, attention deficits, sleep disorders, numbness, dizziness, stiffness in joints, irritability, fatigue, weakness, muscle spasms, depression, and an inability to sit for long.
