The agency posted this statement at 5 a.m. Monday:

 ''Winter Storm Warnings have been expanded into Central Laramie County including Cheyenne through Tuesday morning as heavy wet snow is expected. Melting and compacting of snow is expected throughout this event and therefore the listed snowfall amounts on the map might not reflect the amount of snow that will be observed on the ground at a given time. However, heavier amounts are expected under localized snow bands that develop during the day. Snowfall will result in slick roads and reduced visibility that could make travel difficult at times, especially along Interstate 80 from Cheyenne to Laramie and Interstate 25 from Cheyenne to Wheatland. Stay tuned for the latest updates."
