GRIB Model

RAP North East Pacific - Rapid Refresh

Provider:National Centers for Environmental Prediction, NOAA (USA)
Model scope:Alaska and NE Pacific
Update frequency:every hour
Resolution:0.101°, 6.1nm, 11.2km
Model duration:21 forecasts starting at 1 hr, ending at 21 hrs
Parameters:pressure, wind, wind gust, rain, cloud, temperature, humidity, convection, vertical velocity, simulated radar, visibility, 250 mb, 500 mb, 850 mb
GRIB model date:Mon Apr 19 20:00:00 2021 UTC
Download date:Mon Apr 19 21:11:49 2021 UTC
Download delay:1hr 11min

Note: the Download delay is the amount of time required for the GRIB model to compute its forecast and then for the LuckGrib cluster to download the data and make it available. The LuckGrib delay is generally less than 10 minutes, the remainder of the delay is the model compute time.


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.
