RAP is a weather model NOAA runs hourly, producing short term forecasts. There are several RAP domains.

As can be seen from the image of this models domain, this model covers a large portion of the Alaskan waters, as well as a large portion of the Western seaboard of the North American coast. As this model is updated hourly, it should be very useful for planning day outings as well as watching rapidly changing weather in regions not covered by the HRRR (which is a higher resolution model.)

As RAP is a mesoscale model, it is able to model land and other features at a higher resolution than in a global model, leading to improved forecast accuracy.
