Nowcasting should be best weather forecast for next 6 hours available at the moment with high spatial resolution (INCA have 1x1 km). Is importance lies in current uncapability of nwp models (ALADIN, HIRLAM,..) to run short range forecast in such high resolution. It use all accessible data in the moment of model run. INCA SK run for precipitation every 15 minutes (planed 10 min) and for other variables (temperature, relative humidity, CAPE ...) every hour. INPUT DATA for forecast of precipitation in INCA SHMU AWS = Automatic Meteorological Stations (SHMU) APS = Automatic precipitation stations (SHMU) AHS = Automatic hydrological stations (SHMU) TAWES = Teilautomatischen Stationen (ZAMG) AWS = Automatic Meteorological Stations (IMGW) radar: 2 Slovakia (Maly Javornik (1km), Kojsovska hola (1km)), in near future Austria, Czech (prepared 1km), Hungary, Poland (prepared 1km), OPERA (4km) satelites numerical model ALADIN (nwp SHMU,ZAMG,IMGW) minimal timestep for cumulation in this moment is 15 minutes for arbitrary interval (15min,30min,60min,...3h,6h,12h,48h,..., 1week,...,1 month,...,1year,...)
