Where and when
Location from your phone, a map pin or typed coordinates, with elevation, and how you traveled.
Observations
Tell your avalanche center what you saw.
Forecasters build tomorrow's forecast partly from public observations. Whumpf walks you through every field your center asks for, one short screen at a time, and hands it to the center the way the center takes reports.
What you can record
Every field the center's form has
Red flags
Recent avalanches, shooting cracks, collapsing. Tap yes for anything you saw.
Avalanches
One record per avalanche, or one for several alike: size, aspect, elevation, slope angle.
Snowpack
Hand pits and stability tests, or a full profile with snow depth and penetration.
Wind and weather
Sky, precipitation and rate, wind and loading, blowing snow.
Photos and what you avoided
Captioned photos, and the terrain you stayed off and why.
Everything is saved on your phone as you go, so you can start at the car and file it from the couch.
Three ways to send it
Filed the way your center takes reports
- 1
Your center's own form, filled in
Whumpf opens your avalanche center's public observation form inside the app and fills it in with what you wrote. You check it and tap the center's own Submit button.
- 2
Email with a PDF
Send the observation to the center's inbox with a PDF copy and your photos attached.
- 3
Keep the PDF
Save a PDF for your own records or to send yourself.
Why not post it directly? The National Avalanche Center does not currently issue API access to third-party apps, so Whumpf uses the public routes each center publishes. Your report reaches the center the same way every other public observation does, and the center decides whether and when to publish it.
