This session provides a basic understanding of the eTRaP product, which is used for rainfall prediction of landfalling tropical cyclones. The lesson covers the assumptions that go into creating the product, an understanding of these assumptions is crucial to interpretation of the product. This training session also covers the eTRaP web-page so that the student may efficiently find the products they need. Examples from past cases are shown to improve product interpretation skills.
