Hurricane season is from June until November. It begins over warm ocean water as a low-pressure area, or tropical disturbance. Levels are disturbance-storm-hurricane. Draws energy from warn, humid air at the ocean’s surface. As air rises and forms cloud, more air is drawn in.

1.Dense cold air goes under warm air
2.Warm air rises, expands, and cools
3.Once cooled clouds form:
Rain/Snow=a lot of vapor
Cloudy=a little vapor
4.Moves quickly and causes storms.

~Warm air mass is caught between two cold masses.
~Both cool masses meet and push warm mass up.
~Ground temperature becomes cooler when two cool masses mix.
~Warm air is cut off from the ground and it's water vapor condenses making weather cloudy or rainy/snowy.
