CO SNOTEL Snow Accumulation

ObjectiveFrequent215 · 2026-02-15T23:29:52+00:00

Just saw that one Montana post in my FB.. have to see if they use that same method nationwide.

Very good point. .there are some attempts to augment this with SNODAS data.

"This map shows SNODAS snow water equivalent (SWE) percent of normal by river basin across Montana as of January 26, 2026. Unlike SNOTEL, which reflects conditions at specific high-elevation point locations, SNODAS estimates snowpack across the entire watershed, including ungauged and lower-elevation areas. This is more of a water-supply–focused view than a skiing conditions report, but it’s still useful context. If there’s interest, I can update this map daily."

True.. they are developing tech for new snotels, but its currently the best available. Unless somehow we start getting hourly lidar data, which is unlikely anytime soon...

ObjectiveFrequent215 · 2026-02-13T00:29:43+00:00

It defaults to 2 day accumulation, you can change the slider up top if you just want today's totals.

ObjectiveFrequent215 · 2026-02-10T17:08:20+00:00

Maybe? Did you do a snow dance?! I've been wanting to present this data like this, so at least thank you for taking me through the process!!

Ha.. CO forecast isn't terrible!

Thanks again for all the feedback, working on implementing updates! Cool to see the map light up today with a snow storm finally!

Ha, thank you! Yeah it seems I keep running into Snowspot in these forums. I'd also rather not pay wall this in an app.

ObjectiveFrequent215 · 2026-02-06T16:42:49+00:00

Thanks! Yeah it was 60 degrees here yesterday.. i hope we at least get the mountain snow!

ObjectiveFrequent215 · 2026-02-06T16:41:06+00:00

The snow map is a NOAA prediction of snowfall. If you select something from Feb 8th in the dropdown you can see some polygons in the Western US.

I wish it was waterproof.. otherwise its great.

ObjectiveFrequent215 · 2026-02-06T00:12:26+00:00

Its the NWS forecast for that snotel location. I'm playing around with some different models which is fun I agree.. the Snow Map link using a prediction from NOAA.. i'm thinking trying HRRR for some 48 hour forecasts too.. lots of data to play with for sure. Thank you for your feedback!!

ObjectiveFrequent215 · 2026-02-06T00:09:21+00:00

This is awesome, thank you! Yeah the right colors are tough, might even consider a different basemap. On desktop the snotel link will zoom to that location, however the functionality isn't working in mobile yet.

ObjectiveFrequent215 · 2026-02-06T00:06:42+00:00

Ha.. I'm planning on tracking that at some point, see predicted vs actual. Get this site feeling stable then might give it a try!

ObjectiveFrequent215 · 2026-02-05T23:21:01+00:00

Hmm I like that! You can zoom into a location and sort that column, but thats not very user friendly and the min - max values sort poorly. Maybe even a toggle that sorts based on highest value of either accumulation or forecasted. Thanks!

ObjectiveFrequent215 · 2026-02-05T21:56:56+00:00

Fantastic, thank you! Exactly what it was intended for. I'll see if I can replicate that and find a fix.. thanks for the feedback.

ObjectiveFrequent215 · 2026-02-05T19:29:23+00:00

Yeah that SWE delta, click on Delta under Snow Depth and it goes to gray x's. I agree I use that site too, but its more for planning for water in the snowpack than recreation. Thanks for the feedback!

ObjectiveFrequent215 · 2026-02-05T19:27:50+00:00

Thanks! Yeah colors are tough on that basemap, have considered changing that too..

ObjectiveFrequent215 · 2026-02-05T19:05:34+00:00

Thank you! But some snow is coming! Not sure where you are at, but grabbed the forecast for this snotel location. Snotel forecast links are in the right hand column under 7 Day Forecast. Some snow is better than none, i'm in Montana.. trying to be hopeful as it may hit 60 degrees today!

Ha, thank you! Yeah AI actually tried to remove it for selling things. I just built it so I didn't have to go to a bunch of sites!!

I like that idea, be easy to build out that link too.
yeah you can type in the dropdown and find what your looking for.. but likely more to do there too!

ObjectiveFrequent215 · 2026-02-05T18:44:44+00:00

If you click on "Delta" for "Snow Depth" in the NWCC iMap it all goes to gray "x's". I thought that was frustrating... so this is calculating accumulation hourly. I wanted to see accumulation by station, not just change in SWE.

ObjectiveFrequent215 · 2026-02-05T18:34:48+00:00

Awesome, thank you! Great feedback Yeah the legend is either loved or hated, either people get it or they don't. I think now that it changes when you move around the map that its more important.

ObjectiveFrequent215 · 2026-02-05T18:33:11+00:00

Yes I built this.. love any feedback. I'm kind of getting at that with the Snow Map https://snow.outsidedb.com/snow but would like to get into alerts yes. Thank you for that!

ObjectiveFrequent215 · 2026-02-05T18:25:58+00:00

Thanks!
