As some Utahns continue to dig out of the last winter storm, another one is on the way.
An atmospheric river with plenty of subtropical moisture will interact with an area of low pressure on Wednesday as it moves inland and towards the region. Strong and at times gusty southwest winds will begin to warm temperatures & raise snow levels through the day on Wednesday.
Most locations will begin as snow with the heaviest amounts near the Utah-Idaho border though impacts will be felt as far south as Davis County and east into Summit County. As temperatures rise, most valley locations under 5,000 feet will begin to transition to rain overnight into Thursday as snow levels rise to near 8,000 ft by Thursday afternoon.
Mountain passes and areas will see very heavy snowfall which will lead to near impossible travel for a period of time. With gusty winds and a wetter, heavier snowpack, the avalanche danger will become very high yet again for the northern and central mountains of Utah. Please use extreme caution or wait it out before heading into the backcountry.
In southern Utah, a second atmospheric river event will take place on Thursday with very heavy rainfall below 7,500 feet. Some locations could receive over an inch of rain leading to potential flooding. Heavy mountain snow will make for treacherous travel over the higher elevations so it is recommended that you avoid heading into the mountains until conditions improve.
