Hurricane facts you didnt know.


Do you know how hurricanes form or how they weaken? Do you know what they do? Do you know how they are named? Well if you keep reading you'll find out.

Hurricanes form in low pressure systems out in Atlantic's warm ocean waters. They start out as small tropical storms. Then the wind speed picks up to 74 mph. It has to have a wind speed of 74 mph to be a hurricane. They also have to form in the Atlantic ocean to be a hurricane; if not, its a typhoon. When hurricanes increase in strength (normal about 20 miles per hour differences) the category goes up. Hurricanes become very powerful over open water and decrease in power once they make landfall. Once on land they normally weaken into tropical depressions and dissipate back into the atmosphere. They cause up to multiple millions in damage when they make landfall.

If a hurricane has wind speeds up to 150 mph or more its a category 5 or its deadly. A hurricane is categorized on a scale called the Saffir Simpson Scale. Hurricanes are named by past girl and boys names in alphabetical order. If the last storm that formed was given a boy name, the next formed storm will be given a girls name. Sometimes when a name of a storm has been given and has history of a lot of destruction they will retire the name and never use it again. If a hurricane has strengthened to category 3 it is the beginning stage of a deadly hurricane. A category 1 is still dangerous but it is not considered to be a deadly storm.

I have been researching hurricane Katrina. This hurricane formed on August 23, 2005. It then made landfall on August 29, 2005, six days after it formed. It hit southeast of Nassau in the Bahamas. Once it crossed the Bahamas it entered the Gulf of Mexico. The warm ocean currents in the gulf gave strength to the already huge storm. When it made landfall again in southern Louisiana it was massive destruction machine. Seven years later and there is still signs of damage along Louisiana's shoreline. It costed $105,840,000,000 dollars in damage. It was all categories in different locations as it twirled and twisted through, going from a category one to a category five. It swept through reigning its destruction on the land. It was the biggest hurricane ever to be reported since the big hurricane in Galveston. A storm with the name Katrina occurred one time before the 2005 Katrina. It was a category three having wind speeds of 111 to 129 mph.

I hate to end this early but hurricanes are calling, so a quick review of what I have told you. I have now told you about the forming and weakening of hurricanes. I have told you how hurricanes are named and categorized. I have also told you some cool facts about hurricane Katrina. Well I'm off to explore more hurricanes; so i guess it would be a good thing if you watched the news to see if one is headed straight for you!
