SEVERE WEATHER
TornadoesRising air within the updraft tilts the rotating air from horizontal to vertical. An area of rotation, 2-6 miles wide, now extends through much of the storm.
HurricaneHurricanes begin as tropical storms over the warm moist waters of the Atlantic and Pacific Oceans near the equator. As the moisture evaporates it rises until enormous amounts of heated moist air are twisted high in the atmosphere.
HURRICANES
Winter storms usually form when an air mass of cold, dry, Canadian air moves south and interacts with a warm, moist air mass moving north from the Gulf of Mexico
SNOW STORMS
FLOODS
A flood occurs when water overflows or inundates land that's normally dry.

.
Its produced by a cumulonimbus cloud, usually producing gusty winds, heavy rain and sometimes hail.
THUNDERSTORMS
DUST STORMS
Particles become loosely held mainly due to drought or arid conditions, and varied wind causes. Gust fronts may be produced by the outflow of rain-cooled air from an intense thunderstorm.
Hail is formed when very strong thunderstorm updrafts meet supercooled water droplets.
HAIL STORMS
WATERSPOUTS
The water inside a waterspout is formed by condensation in the cloud. Tornadic waterspouts get their start as true tornadoes. Similar to tornadoes but they occur over water.
.
A heat wave occurs when a system of high atmospheric pressure moves into an area. In such a high-pressure system, air from upper levels of our atmosphere is pulled toward the ground, where it becomes compressed and increases in temperature.
HEAT WAVES
WILDFIRE
A lot of wildfires are caused by humans but they are also caused by lightning and high temperatures.
