I'd be grateful if your meteorologist could explain their frequent use of the term "Jetstream" - a quick wiki search might help.
Battery drainer It has good information on the snow and the live cameras are great but it will drain your phone's battery in the blink of an eye.
Nice info all in one app but... On my Samsung Note 2 LTE running Android 4.3, this app is constantly in wake status and keeping the GPS actively searching despite exiting the app. This results in it chewing through my battery (23% in 4hr) despite only having the app open for a couple minutes to test. I had to manual force close the app. Otherwise loads of great info on the Niseko area with a nice preloaded map for those who are trying to avoid roaming data charges.
This app is awesome and when visiting Nesiko Hirafu area the app provided fantastic information and updates on skiing and weather.. Visit Nesiko for the most amazing powder snow and Japanese hospitality.
Beware This continually drained my battery
GPS battery drain supreme Once opened once it tries to find you using GPS but it leaves your GPS on, crushing battery life. Need battery on the slopes guys, sorry. Uninstall
