The first major Pacific storm of the wet season is forecast to wallop the West Coast. … Some Bay Area cities could record their wettest September day in decades. Showers will remain in the forecast Monday through at least Wednesday. … Rain showers are expected to linger across Northern California on Tuesday, where snow may mix in at the summits of Tahoe ski resorts. … Although the rain probably won’t be enough to completely end fire season in most places, it should moisten vegetation considerably and lower fire risk significantly, especially in the Coastal Ranges and northern Sierra.
