How do you make the Global Storm Forecast?

the ECMWF (European) model and make
adjustments to make sure it correctly
shows the precipitation type, while also
optimizing the map performance for fast
loading and global viewing (over land and
water).

- Purple = mix
- Orange = sleet
- Pink = freezing rain
- Blue = snow
How often is the Global Storm Forecast updated?
The Global Storm Forecast is updated every 12 hours with
the latest available forecast
data.
How long are the 'jumps'
between forecast images?
The 'jumps' between forecast
images are 3 hours for the first 120
hours (five days) and then 6 hours out
through 360 hours (fifteen
days).
What resolution is
the Global Storm Forecast?
The Global Storm Forecast is
currently available in 25 km (15 mile)
resolution.
Are there any limitations to
the Global Storm Forecast?
The Global Storm Forecast is only from one model (ECMWF) and not
blended with multiple models like you see
elsewhere on OpenSnow. The forecast is
also lower resolution so it will not
always pick up the nuances of complex,
mountain terrain. We recommend
double-checking the forecast for any
location by tapping the map to view the
full forecast details.
