Hurricane Wiki:Work needed

Articles wanted
Unlike articles on Wikipedia, these are not so much supposed to be encyclopedic articles. Sourcing is not a big deal, and Original research is fine (as long as it is not untrue or an attack). However, the introduction to all of them should be written in an encyclopedic tone to give appropriate context.

Organisations
These should be more focussed on the products produced by the organisations listed than a description of the organisation. They should also describe how to interpret the stuff provided.

 * Joint Typhoon Warning Center
 * Japan Meteorological Agency
 * Bureau of Meteorology
 * Fiji Meteorological Service
 * India Meteorological Department
 * Meteo-France
 * PAGASA

Again, these should be focussed on how to use the information from these sources, rather than an encyclopedic description of the source.
