Hurricanes can be good for the environment with the rain, but they can also destroy a life. Hurricanes can topple buildings, uproot trees, tear down power lines, and create floods. Hurricanes create powerful winds and a substantial amount of rain. Large amounts of water can create mold, which can be extremely dangerous. Hurricanes, or any large storm, affect many countries and families. Hurricanes are immensely unsafe and unpredictable, both because of their own power and the fact that tornadoes can materialize from their circular speeding winds.
Hurricanes form through an intricate process. Before they get the status of “hurricane,” they must meet specific conditions. Meteorologists separate the life of a hurricane “into four stages: (1) tropical disturbance, (2) tropical depression, (3) tropical storm, and (4) hurricane” (Emanuel 453). A tropical disturbance is a region or area where rain clouds are beginning to form. The clouds form when moist air rises and becomes cool, which cannot hold as much water vapor as warmer air, and these clouds may rise to great heights. Meteorologists classify these towering thunderclouds as cumulonimbus. These cumulonimbus clouds normally create heavy rains “that end after an hour or two, and the weather clears rapidly” (Emanuel 453). However, if the set of conditions is correct for a hurricane, more clouds will continue to form, creating more energy. If this build-up produces wind speeds of up to 38 miles per hour, the storm is classified as a tropical depression. A tropical depression is a low pressure area near the ocean that creates wind, which in turn evaporates more seawater, feeding the thunderclouds. The winds swirl slowly at first, then, as the pressure becomes even lower, the winds pic...

Nearly 45 years ago one of the most powerful and damaging weather phenomenon’s ever to be recorded slammed into the shores of the Gulf of Mexico, a storm that effected people far and wide. Camille formed on August 14th just west of the Cayman Islands and rapidly intensified overnight becoming a category 3 hurricane approaching the island of Cuba. The storm trekked north-northwestward across the Gulf and became a stage 5 hurricane and maintained its strength before making landfall on the Mississippi Coast on the eve of August 17th. The devastating aftermath in the weeks to follow induced by the winds, surges, and rainfall took the lives of 256 people, and caused an estimated damage of 1.421 billion dollars.
Once there was, as never before, a hurricane of great might and strength. As never before, there once was a hurricane of many names: storm, cyclone, tempest, typhoon, and flood. Yet it has lived on in history as the Great Galveston Hurricane of 1900. Humanity has glorified and immortalized the hurricane. The Great Galveston Hurricane has been the subject of numerous articles, novels, plays, and poems, as well as four major nonfiction studies (Longshore).
During the morning hours of August 29, 2005, Hurricane Katrina struck the Gulf Coast. Sustaining winds of 100-140 miles per hour and stretching some 400 miles, the storm

B. Relevance: Illinois rests on the boundary of what tornado researchers call tornado alley. This is the area of the country that receives the most tornadoes every year. According to a 1995 brochure distributed by the National Oceanic and Atmospheric Administration (NOAA), Illinois averages 27 tornadoes a year. Also, nearly 5 people die every year in Illinois as a result of tornadoes [ AID]. In fact, according to Tornado Project Online!, a website hosted by a company that gathers tornado information for tornado re searchers, the deadliest tornado in U.S. recorded history occurred in Murphysboro, Illinois. In 1925 a violent tornado killed 234 people in this Southern Illinois town.
Hurricanes are born over the warm waters of tropical oceans and are formed by a low-pressure system caused by the heating of water. The heat causes the air to rise and form lower pressures in a feedback loop, making the hurricane stronger. Heavy rain results from a condensation of water and strong winds develop from warm air rushing to the eye of the hurricane. Essentially, greater storms and winds occur when the hurricane feeds of the rising temperature of the water. In addition, researchers studied disturbances and intense thunderstorms in the atmosphere over Western Africa and believe they are partly to blame for extreme hurricanes affecting the United States and Canada. While these are all the main ingredients of a perfectly natural process, they were not the primary causes of the damage done by Hurricane
On August 29th, 2006 New Orleanians were expecting a total of 12 to 15 inches of rain and extended five or six inches from the upcoming storm later known as the costliest hurricane in U.S history. The Category 3 hurricane devastated most of eastern North America with blustery winds of 170 mph (280 km per hour) and storm surge values ranging from 10 to 20 feet. The storm called ‘’Hurricane Katrina’’ originated in the Bahamas on August 23th, 2005, but only became a devastation the next day. On August 28th, Hurricane Katrina succeeded a Category 3 hurricane(sustained winds of 122 kt) and exceeded the limits of a Category 5 storm (sustained winds of 136 kt). The following day, the cyclone shifted northwest towards Mississippi and Louisiana, where the hurricane hit the hardest. New Orleans was one of the cities where the most damage was caused; leaving a negative environment, residential and economic effects on the Gulf Coast.

Tropical waters serve as the perfect breeding and growing place for a hurricane. Storms, such as Katrina, are able to develop because of the availability of water vapor over tropical oceans. This creates the ideal environment for the growth of a hurricane (Ahrens & Sampson, 2011).
Hurricanes form over the ocean. Easterly waves, what hurricanes develop from, are long, narrow regions of low pressure which occur in ocean winds called trade winds. At first, these easterly waves can grow into something called, a tropical depression. A tropical depression occurs when winds are up to 31 mph. Then tropical depressions can be upgraded into a tropical storm if the winds reach speeds of 74 mph or less. Then finally a the storm can be bumped up into a hurricane if the winds reach 75 mph.

In the hurricane the mixture of the water and winds can be extremely damaging. The winds are extremely dangerous and usually don’t go faster than about 75 miles per hour but have been documented to go as fast as 85 miles per hour. Due to the fact that hurricanes need water to survive they cannot go too far on land, but that does not stop them from causing billions of dollars in damages. Hurricanes are so dangerous that they were listed number 1 on the Department of Earth and Atmospheric Sciences, Hazard and Disasters list.
A hurricane is a type of natural disaster that can be harmful and destructive to anything in its way. Every year five to six hurricanes are formed, damaging and destroying people’s homes, landmarks, and anything in its path (“Hurricane”). Before a hurricane is developed it is known as a tropical storm. To be a tropical storm wind speed must be at least thirty eight miles per hour (“Hurricane”). Once wind speeds reaches seventy four miles an hour it can then be classified as hurricane (“Hurricane”). Large scale storms, like hurricanes have a variety of ways to measure the sev...
