Tucson isn’t exactly sparsely populated, and seeing as it is slowing down a bit as it goes up the Baja it will turn into a major rain event for southern Arizona.
Also, depending on how it tracks southern California would be on the dry side but with some hefty winds which won’t exactly help the fire situation there.
That was my basic point - the worst of the winds will probably only affect sparsely populated areas on Baja - but if the remnants make it to Arizona, there could be some loss of life from flash flooding. Doesn't take a whole lot of rain in the desert to trigger such.
