It’s not the greatest news for source regions that supply runoff to Lake Mead and Lake Powell. The dry Fall and early Winter so far has lead to below normal snowpack in the Upper Colorado River Basin, as well as the Virgin River Basin. Its early, we are expecting a more unsettled weather pattern to develop over the west next week. Plus there are 2 to 3 months left to add additional snowpack.
North winds will increase Saturday especially along the lower Colorado River Valley. A Wind Advisory is in effect from 8 AM PST Saturday morning to 5 PM PST Saturday afternoon. The strongest winds will occur between Lake Mohave and Lake Havasu with gusts to around 45 mph. Gusts of 20 to 30 mph can be expected across much of Lake Mead. Winds will make driving difficult for motorcycles and high profile vehicles and will create hazardous boating conditions.
