The Rain Map in the PredictRain app allows you to see a graphical rain forecast overlayed over a geographical map by available weather model at the highest resolution available up to 1km.
Weather models include PWG, PWE, ECMWF, GFS and UKMO. GMDSS weather warnings and Lightning can be overlaid on the map or toggled off.
To view the Forecast Options, tap on the weather model drop-down box in the top right corner of the screen. From there you can toggle the options to choose your preferred forecast weather model, resolution, display type, GMDSS/Lightning overlay and animation speed.
To select a 1km weather model, select either PWG or PWE.
