SALT LAKE CITY — The mild and sunny weather is poised to give way to winter this weekend with a storm that will blast the mountains with snow and deliver rain and high winds to the valleys.
The National Weather Service in Salt Lake City said a low pressure system is hovering over the Pacific Ocean and is expected to arrive in Utah on Saturday, with rain to fall that evening.
In advance of the storm, which is coming from the south, western valleys will have winds from 30 to 50 mph, with gusts to 65 mph. The eastern valleys will be with hit with winds from 25 to 35 mph and possible gusts to 55 mph.
Brian McInerney, hydrologist with the National Weather Service, said the storm will produce significant snow accumulations for mountains throughout the state at elevations of 5,000 feet or above.
Travel could be hazardous in the mountain areas and particularly on east-west routes such as I-80, U.S. 6 and I-70 during the high-wind periods.
The storm is expected to last into Monday in the southern half of the state and into Tuesday for the northern portion.
Additional weather briefings will be held Friday and possibly this weekend.
