During La Niña, the U.S. Southwest, central and southern Rockies, Great Plains, and Florida usually experience drier weather.
Notes on verification
Well-corroborated by NOAA, PMEL, and Drought.gov climatological data showing consistent La Niña-related drying patterns across the southern U.S. and southern Rockies; minor variability noted for 'central Rockies' but broadly supported by drought and outlook data.
