Tetons

At the mid and upper elevations well-developed crusts exist. Dry snow avalanches are unlikely. Cooler temperatures and clouds should keep the wet snow avalanche hazard at bay. At the lower elevations crust will soften. Monitor conditions for the development of wet snow avalanche hazards on isolated terrain features. With warm valley temperatures and a chance of rain showers roof slides are possible. Grand Teton National Park has extended its bighorn sheep winter habitat closure on Mount Hunt and in the Prospector Mountain/Static Peak area from April 1 until April 30. Please respect these closures.

Light snowfall with periods of moderate snowfall will continue overnight and into Wednesday. Rain will change to snow this evening as the freezing level drops. Accumulations of 4 to 8 inches are possible in the mountains by tomorrow evening. On Wednesday temperatures will in the 20s and 30s in the mountains. Valley temperatures are forecast to be near 30 in the morning and rise into the 40s. Light southerly winds will begin to veer to the southwest and increase to 10 to 15 miles per hour by Wednesday night.The general avalanche hazard is expected to be low. At the upper elevations isolated pockets of new soft slab and shallow loose snow sloughs could begin to become a hazard in terrain features with consequences. Monitor conditions for increasing dry snow avalanche hazards at the higher elevations and for wet snow avalanche hazards on isolated terrain features in the lower elevations.
