What's new at PRISM
Gallery of State Maps
In response to requests for high-quality graphics suitable for printing, annual precipitation maps are available for each of the 48 contiguous states. The 30-year normals datasets are used for this purpose, since they are our most popular data. 30-year normals describe average annual conditions over the most recent three complete decades. See PRISM datasets for more information.
