Transcript of Hurricanes
5th period Hurricanes What is a Hurricane? Evacuating plans Evacuating plans (cont.) Pictures A hurricane is an intense, rotating oceanic weather system that possesses maximum sustained winds exceeding 119 km/hr (74 mph). It forms and intensifies over tropical oceanic regions.
Hurricanes are generally smaller than storms in mid-latitudes, typically about 500 km (311 miles) in diameter. At the ocean’s surface, the air spirals inward in a counterclockwise direction. This cyclonic circulation becomes weaker with height, eventually turning into clockwise (anticyclonic) outflow near the top of the storm. Why should you obey the advice

Wills, deeds, and copies of recent tax returns — If you live in a high-rise building – hurricane winds are stronger at higher elevations. — If you live on the coast, on a floodplain, near a river, or on an island waterway, read more about evacuating yourself and your family. If you are unable to evacuate, go to your wind-safe room. If you do not have one, follow these guidelines: — Stay indoors during the hurricane and away from windows and glass doors.
— Close all interior doors – secure and brace external doors.
— Keep curtains and blinds closed. Do not be fooled if there is a lull; it could be the eye of the storm – winds will pick up again.
— Take refuge in a small interior room, closet or hallway on the lowest level.
— Lie on the floor under a table or another sturdy object.
— Avoid elevators. Because of the destructive power of a hurricane, you should never ignore an evacuation order. Once an evacuation is ordered, you should leave as soon as possible.
