Footloose Sports Online Seasonal Rentals10-24-21 @ 6:48 AM Good morning, and welcome to storm watch day.

The long-awaited Big October Base Storm is just about to start on Mammoth Mountain and across the Eastern Sierra.

Estimated snowfall totals look great for an October base storm. Remember the snow that falls is going to be solid base, you’re not going to sink down and hit rocks and stumps.

Now it’s time to watch and see what magic the storm performs on Mammoth Mountain.

Take into account that over the years storms like this can easily overperform what is forecasted with what I call the funnel effect. 

Weather Forecast: If you’re traveling in the area expect rain below the 9000-9500 foot level today with the rain turning to snow down to about 7500 feet on Monday morning. 

The following alerts have been posted by the NWS for this afternoon into Monday afternoon. Winter Storm Warning, Flood Watch, and a Wind Advisory for Mono County. Down in Inyo county along 395, there is a wind advisory with a Winter Storm Warning posted for the Mountains.

Looks like the upper mountain could get 2-3 feet or more. For the complete snowfall outlook numbers use this link for complete Mammoth Weather information.

Road Conditions: As of now we do not see any chains needed for 395 south of Mammoth Lakes. You will need them in Mammoth Lakes and all the roads up to the ski area if you are not in an AWD or 4 x 4 with snow tires.

All passes and back roads above 9000 feet have closed ahead of the storm now. They are likely closed for the season.

Roads that are closed into the National Forest are still open for hiking, skiing, snowshoeing, and snow play unless signed closed for such activities.

The Mammoth Snowman Snow Report: Mammoth Mountain plans to open for skiing and snowboarding on Friday at 8:30 AM. Based on the forecast and the data that backs it up, I see top to bottom skiing via Cornice possible for opening weekend.

Let’s hope this storm overperforms what’s forecasted, would love to be able to ride the Drop Outs early season.

This is going to be the season to get up here early and get those legs snow shape ready for the big dumps that will be coming our way soon. The first 2 weeks of November should be great out on the hill, make plans to join us for some snowtime fun.

Website News: I will be back out on the hill if all goes as planned on Opening Day this season and then several times a week grabbing photos and video to post up for your enjoyment.

We did purchase all new macs and go pro stuff to get back into video production this season. Look for weekly Snow and Weather videos now as the calendar hits November 1st.  If you enjoy all the posts, photos and videos please consider becoming a monthly community supporter.

Fall Colors: It’s been an amazing season of Fall Color in the High Country. Everything will be past its peak for the season once this storm has come thru the area.

You can expect the color show to continue after the storm in the Bishop and Round Valley areas. I will be doing the Mammoth to Bishop beta drive for Fall Colors again on Tuesday and will have one last update on Fall Colors on Wednesday.

Mountain Biking: Looks like some decent rain on all the Mountain Bike trails from Bishop up to about Mammoth Lakes.

Got to be excited for some brown pow rides early this week. Locals’ choice this week will be Chipmunk Canyon and of course Lower Rock Creek Canyon. I will post more information on Mountain Biking soon.

Author – Steve Taylor – The Mammoth Snowman Over the last 30+ years, Snowman has spent countless hours studying and learning about Mammoth Mountain Weather and Snow Conditions first hand. He has been skiing around the hill with marked ski poles since March of 1991 so he can measure the fresh snowfall amounts out on the hill. 

Snowman started blogging this information back in 1990 on the old Mammoth BBS system, then the RSN Forums and then on to in 2004 with Video & Photo Blog report. (No YouTube back then). Facebook got added to the fold back in 2008 and then the Facebook Group in 2016. 

Reports, videos, and photos from the website have been featured on both local TV Stations here in Mammoth, along with AP, Fox, ABC, CBS, and NBC News.
