  • Very clear, with well chosen facts. You need to know what category the hurricane was though. Why did more people die in this one than in Hurricane Floyd? james clarke

  • I like the hurrican introduction at the start, and the factfile makes information easy to access for your case study. Good images, you need to select the most relevant ones though as there are lots. Also, there are some large sections of information near the end, there is too much to remember so try and write the key points in your own words. Well done, excellent ICT skills. Miss Power

  1. 1. Tropical Storms And how they form
  2. 2. <ul><li>Tropical storms are low pressure weather systems known as either….. </li></ul><ul><li>Cyclones </li></ul><ul><li>Typhoons </li></ul><ul><li>Willy-willies </li></ul><ul><li>…… .in different parts of the world </li></ul>
  3. 3. <ul><li>Their source are in the regions of the major Oceans between the Tropics of Cancer and Capricorn </li></ul><ul><li>These form when sea temperatures reach over 27c and only occur for a few months </li></ul>Click to link Click to next page

  19. 19. Aftermath Criticism of FEMA Flooding in Greenville, North Carolina on the Tar River The Hurricane Floyd disaster was followed by what many judged to be a very slow federal response. Fully three weeks after the storm hit, Jesse Jackson complained to FEMA Director James Lee Witt on his CNN program Both Sides Now , &quot;It seemed there was preparation for Hurricane Floyd, but then came Flood Floyd. Bridges are overwhelmed, levees are overwhelmed, whole towns under water ... [it's] an awesome scene of tragedy. So there's a great misery index in North Carolina.&quot; Witt responded, &quot;We're starting to move the camper trailers in. It's been so wet it's been difficult to get things in there, but now it's going to be moving very quickly. And I think you're going to see a — I think the people there will see a big difference [within] this next weekend!&quot; Click to link Click to next page

  21. 21. Ecological effects Runoff in the aftermath of the hurricane Runoff from the hurricane created significant problems for the ecology of North Carolina's rivers and sounds. In the immediate aftermath of the storm, freshwater runoff, sediment, and decomposing organic matter caused salinity and oxygen levels in Pamlico Sound and its tributary rivers to drop to nearly zero. This raised fears of massive fish and shrimp kills, as had happened after Hurricane Fran and Hurricane Bonnie , and the state government responded quickly to provide financial aid to fishing and shrimping industries. Strangely, however, the year's shrimp and crab harvests were extremely prosperous; one possible explanation is that runoff from Hurricane Dennis caused marine animals to begin migrating to saltier waters, so they were less vulnerable to Floyd's ill effects. Pollution from runoff was also a significant fear. Numerous pesticides were found in low but measurable quantities in the river waters, particularly in the Neuse River . Overall, however, the concentration of contaminants was slightly lower than had been measured in Hurricane Fran , likely because Floyd simply dropped more water to dilute them.
