The new snow maps are already pleasingly colorful this time! We particularly like the +4 days view at the moment. The snow depth is still not quite as satisfactory, but this should improve with the coming snowfall.

We have weather!
The PG weather service starts the season
The PowderGuide weather service is back so you can follow the snowfall forecast for the weekend on the PowderMap again! As usual, in addition to new snow forecasts, a forecast text and the SNOWGRID and sunshine maps are also available.

INCA and SNOWGRID
As before, the data behind the colorful maps comes from the ZAMG (Central Institute for Meteorology and Geodynamics = Austrian Meteorological Service) and is based on high-resolution regional forecast models. The higher resolution means an improvement in forecast quality compared to large, global models (ECMWF, GFS), especially in areas with very different small-scale topography. The latter only resolve the largest mountain valleys at all and see the Alps as a uniform, relatively smooth flow obstacle and not as a complex mountain range.
SNOWGRID is ZAMG's operational snow cover model, which is linked to INCA (analysis and forecasting of various weather parameters) and calculates the current snow depth and changes in snow depth. Measured values from weather stations are also included in the calculation, so that the snow depths in regions with many weather stations are generally more accurate. SNOWGRID has a resolution of 100x100m. This means that there is a value for the snow depth on an area of almost 1.5 soccer pitches.
The PowderMap
The PowderMap is the PowderGuide weather forecast in the form of an interactive map. You can switch back and forth between the various parameters (snow, sun, etc.) and also display the text forecasts or current ConditionsReports. Watch the video for a more detailed explanation of the PowderMap:
We hope that the forecasts live up to their current promises and that winter 2021/22 still has plenty of colorful new snow maps in store!

WeatherBlog 3 2021/22 | Wintery prospects!
Lea Hartl • 11/24/2021
Since the beginning of the week, the very mild phase that has kept us busy recently has come to an end. High pressure still prevails in the Alpine region and the weather is autumnal in character, with high fog in many valleys and sunshine for those who make it out of the fog. A change in the weather is on the horizon for the weekend, which should make the whole Alpine region feel much more like winter. -
World of Science | How much did it really snow?
Lea Hartl • 01/16/2017
Ever since we got the SNOWGRID maps on PowderGuide, we've been getting questions about their accuracy: Why is there much more snow here in my favorite forest slope than on the map? SNOWGRID says there's two meters of snow in Ticino, but my buddy says there's nothing at all? Below we provide some insights into the complex world of precipitation measurement, the efforts of ZAMG to record snow as accurately as possible and why it still doesn't always work. -
SNOWGRID at PowderGuide
PowderGuide • 01/01/2017
As of today, SNOWGRID maps from ZAMG for Austria and some neighboring parts of the Eastern Alps are available on PowderGuide. SNOWGRID is a high-resolution snowpack model that shows the spatial distribution of the snowpack in the terrain very well. We now have the current snow depth and the change in snow depth over the last 24 hours as a separate sub-category in the Weather/Snow section and are pleased to be able to offer this service together with ZAMG.
