Latest News – Wallowa Avalanche Center

Expect one last day of unseasonably warm weather today (Monday April 19). Tuesday through Wednesday a strong cold front with mountain snow will be our weather story.

During this warm spell numerous wet slides have been occurring on nearly all aspects at mid elevations. Some can be seen from Joseph on the Chief Joseph Mountain ridgeline.

Night-time temperatures the last several days have been at or above freezing. Therefore the existing snow surface has not had time enough to refreeze and solidify. This new snow will be landing on a very wet (unfrozen) old snow surface after yet another warm day today and above freezing temps tonight. The NWS has the storm beginning as rain early tomorrow morning even at 9000 feet. See the Aneroid Mtn milepost forecast on our Local Weather button.

Be mindful that this new snow will be very susceptable to avalanching when traveling in avalanche terrain.

We will update this blog if any new information comes our way between now and the end of April. Please see our final summary (issued 4-9-10) for additional things to watch for throughout the remainder of the season.
