Introduction
This website of the World Meteorological Organization (WMO) is aimed to serve as a platform for the information sources for tropical cyclone forecasters to obtain data and tools which are useful for monitoring and forecasting of tropical cyclones. Forecasters may access the various sources providing conventional and specialized data/products including those from numerical predictions and remote sensing observations as well as forecasting tools concerning tropical cyclone development, motion, intensification and wind distribution. It will continue to develop along with the availability of new data and products and will also contain techniques and best practices from tropical cyclone forecast centers that could be adapted by other forecast centers.
