Wondering how these forecasts are created? Forecasters from your local National Weather Service Forecast Office in San Juan, Puerto Rico use what is called IFPS to create hourly forecasts of sensible weather elements such as sky cover, temperatures, dew point temperatures, wind speed and direction to just name a few. The data is then used to create the forecast text and images you see on our site. You can read more about IFPS and our National Digital Forecast Database site by clicking here.
