Good find, tracking down through the document to page six precipitation graphics d and f it show an increase of 1 to 2.5 mm/d which adds up to 14.4" to 35.9" per year. A prairie will prosper with 12" per year and Forests prosper above about 28" per year. Needless to say the region is much lower in 'normal' years, for example Ensenada, a reasonable city in Baja California averages 265 mm aka 10.4" of rain per year. It looks like the increase rainfall will extend from south of Baja all the way to San Fransisco.
