GRIB Model

NAM Caribbean - North American Mesoscale Forecast System

Provider:National Centers for Environmental Prediction, NOAA (USA)
Model scope:Caribbean
Update frequency:every 6 hours
Resolution:0.11°, 6.6nm, 12.2km
Model duration:23 forecasts starting at 0 hr, ending at 3 days 12 hrs
Parameters:pressure, wind, rain, cloud, temperature, humidity, convection, simulated radar
GRIB model date:Mon Jul 15 18:00:00 2024 UTC
Download date:Mon Jul 15 20:58:56 2024 UTC
Download delay:2hr 58min

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.


NAM Caribbean is a high resolution nest, that runs within the larger NAM suite of models. NAM is a mesoscale model, which means that the numerical analysis is able to model land, and other features, at a higher resolution than in a global model, leading to improved forecast accuracy.
