current conditions Skies are partly to mostly cloudy this morning, as the remains of a storm clip northern Utah. No snow involved, but definitely the coldest temperatures we’ve seen in a while. This morning, in the Provo area mountains it's in the teens at the mid and lower elevations. If you're heading into the alpine terrain, expect single digits. Winds speeds have been variable, with averaging peaking at 10 to 15 mph, gusting to 20, at the mid and low elevations. Upper elevation wind speeds to the north are averaging 25 to 30 mph, with gusts to 40 mph, and I would expect similar speeds at the higher elevations in the Provo area mountains.. The solid overnight refreeze will soften little today, but the best chance is on steeper south and westerly facing slopes if the sun comes out where you are. A new observation noted that isolated areas received up to 4” of snow from the Sunday storm just to the north. Elsewhere, the icy hard snow surfaces will make for fast travel, but are slick |

description
Wind slabs: hard or soft shallow wind drifts may be scattered along the high ridge lines, created by several days of west to northwesterly winds. It is a matter of terrain – if one cracks out beneath you on a steep slope, knocking you off balance, it’s possible to go for a long ride down an icy slope or get sent over a cliff. Cornices: The huge cornices can still fail with the additional weight of a person. Stay well back from their edges, and avoid travel below them. Slide for life: If you plan to travel in steep, icy terrain, have a way to prevent a “slide for life” from happening. Whippets, mountaineering axe, ski or boot crampons and/or using a rope to belay are safety measures that can help prevent an accident. |

weather Partly cloudy skies this morning may give way to more sun this afternoon. Temperatures, however, will remain cold, warming only into the low 30s at 8,000’ and the upper teens at 10,000’. The northwesterly winds are forecast to decrease, averaging 5 - 10 mph by afternoon, with speeds across the highest peaks dropping into the 15 to 25 mph range. Several days of warm, sunny weather will return tomorrow as a ridge of high pressure moves over the state, accompanied by a huge temperature jump. 10,000’ temperatures will soar into the low 30s on Wednesday and the upper 30s on Thursday. Friday will be warm and very windy, followed by a series of colder storms Saturday into next week, with a nice refresh of new snow. |
