As well as covering floods this section of the syllabus also includes hurricanes.
This animated guide of hurricane formation is a good starting point. Go to this BBC webpage and click on the first short clip to show how a hurricane is formed. http://news.bbc.co.uk/1/hi/sci/tech/4588149.stm
Revision notes on hurricanes can be found here on S-cool http://www.s-cool.co.uk/topic_quicklearn.asp?loc=ql&topic_id=7&quicklearn_id=5&subject_id=20&ebt=101&ebn=&ebs=&ebl=&elc=4

For our LEDC case study we looked at cyclones in Bangladesh and there is a podcast here http://geocrest.podomatic.com/entry/2007-03-15T09_53_21-07_00
Watch this You Tube video as it compares Hurricane Katrina (which hit MEDC) and Hurricane Mitch (which hit LEDCs). You would need more information for your case studies but the film will go with your (hopefully) completed case studies in class! http://www.youtube.com/watch?v=JbHlMOvQ7Wk&eurl=http://geographygcse.blogspot.com/search/label/Weather%20hazards
There is also an indepth look at Hurricane Katrina on the BBC http://news.bbc.co.uk/1/hi/in_depth/americas/2005/hurricane_katrina/default.stm
