While still somewhat disorganized the National Hurricane Center is forecasting it to move northward just west of the Baja Peninsula over the weekend.
Although it is not forecasted to reach Hurricane strength prior to weakening over the colder water, the upper air pattern now in place will lead to a large influx of tropical moisture initially into the Desert Southwest over the weekend, and to a lessor extent northward affecting Star Valley, possibly by the first of next week.

We are now in a daily regime of afternoon showers and thunderstorms, which will continue through the weekend. For Friday there were a few areas that received substantial showers, mostly notably in the Pocatello area.
