From an AP story by Jordi Lebrija and Damian Dovarganes headlined “Rain from Tropical Storm Hilary lashes California and Mexico, swamping roads and trapping cars”:

Tropical Storm Hilary inundated streets across Mexico’s arid Baja California Peninunsula with deadly floodwaters Sunday before moving over Southern California, where it swamped roads and downed trees, as concerns mounted that flash floods could strike in places as far north as Idaho that rarely get such torrential rain.

Forecasters said Hilary was the first tropical storm to hit Southern California in 84 years, bringing flash floods, mudslides, high winds, power outages and the potential for isolated tornadoes.
