Avalanche Advisory
Advisory: Ogden Area Mountains Issued by Evelyn Lees for Saturday - March 18, 2017 - 6:57am
bottom line

START and FINISH EARLY TODAY – consider BEING OUT OF THE BACKCOUNTRY BEFORE NOON. The avalanche danger will rapidly rise to MODERATE this morning - wet loose sluffs are possible on steep slopes of all aspects and elevations. Once the snow becomes wet, sloppy or unsupportable where you are, head for low angle terrain and avoid travel beneath steep slopes. In isolated places, natural avalanches are possible today.

Avoid travel below the huge sagging cornices and opening glide cracks

current conditions

Under mostly clear skies, temperatures below freezing just aren’t happening this morning. It's in the low 40s to 50 degrees in the Ogden area mountains. The southerly winds have increased at the mid elevations, averaging 15 mph, with gusts 25 to 30 mph. Along the high ridge lines, average speeds are 35 to 45 mph, with gusts in the 50s at times.

Just when you thought it couldn’t get any hotter…along comes a record-breaking day. The superficial refreeze at the low to mid elevations will rapidly soften, and the snow become wet and sloppy. Wet loose sluffs can be triggered today on all aspects and elevations except the highest, northerly facing slopes. I’m counting on todays’ wind and occasional clouds to help cool the snow. But be alert to the heating snow where you are in the backcountry – wet, punchy, sloppy snow means it’s time to head out of the backcountry, or at least to stay on lower angle slopes and avoid run-out zones of steeper avalanche paths. Natural avalanches may be possible today.

On Thursday, Paige used green "juice" (Happy St. Patty's Day!) to emulate Mark Staples' previous Tang experiment. The dark green line shows where there is a firm crust though that too is deteriorating. With continued warm temperatures, wet avalanches will continue to be a problem until we get a solid refreeze.

Enormous cornices still dot the ridge lines, drooping in the heat. Avoidance is the key - stay way back from the edges of the cornices (they always break back further than expected) and minimize any time spent beneath.

Glide cracks are opening through out the range, and occur primarily where there are smooth rock slabs beneath the snow. Glide cracks south of Rodeo Ridge, Paige's photo from Thursday.
weather

Skies will be mostly clear this morning, but high thin clouds are sneaking over the border, which will bring varying cirrus. Temperatures will soar into the mid 60s at 8,000’ and remain in the mid 40s along the high ridge lines. The southwesterly winds will average 15 to 20 mph. For peaks favored by the southerly flow, averages of 35 mph with gusts to 55 mph, will occur. A dry cold front tonight will bring some relief, with temperatures finally dropping below freezing. After a brief warm up on Monday, temperatures will be on a downward slide this week, with chances of several small shots of snow mid week into next weekend.
