The same storm system that packed quite a wet punch from Los Angeles to Phoenix and Las Vegas Thursday and Thursday night will head to the four corners on Friday.
A concentrated area of soaking, heavy showers and thunderstorms will hammer areas such as Grand Junction, Durango, Santa Fe and Albuquerque.
In some areas, rainfall will exceed one inch or more in only a couple of hours. Places that receive rainfall of this magnitude will have rapid flooding of small streams and normally dry washes.
Along steep canyons, ravines and mountainsides, dangerous mudflows and rockslides are possible.
In the highest elevations and ski resort areas, such as Telluride, Steamboat Springs, Vail and Aspen, the first winter storm of the season will dump 4-8 inches of thick, wet snow.
If you will be driving though mountain and back country roads, hiking wilderness trails, camping or sightseeing, be prepared for flooding or rapidly changing snow levels.
Heavy snow can bring down tree branches and snow packed roads over high mountain passes can make traveling impossible.
Be sure to have a plan of action if you get into trouble and to let someone know which trails or roads you will be taking.
Also, be aware that flood waters can travel a long distance from the origin of the rainfall through dry wash channels and stream/creek/river beds.
This storm will exit the Four Corners Saturday and move on the Nation's Heartland for Saturday.
