While flooding remains the first and foremost concern with the final storm in the series to pummel California and the Southwest, strong thunderstorms pose additional threats today.
As if Californians and Southwest residents haven't had enough to deal with, locally damaging winds, hail, and perhaps even a handful of waterspouts and tornadoes are all possibilities with today's thunderstorms.
Gusty winds reportedly toppled a 75-foot tree onto a house in Whittier, Calif., around midnight, according to KABC-TV. Trees have also been downed in Newport Beach and Claremont, Calif.
The most common impact, however, with today's thunderstorms will be torrential downpours that exacerbate flooding problems, which have already been a huge issue for the region over the last few days.
The thunderstorm threat will be greatest early today in Southern California before shifting farther east into western Arizona later this afternoon and evening. Portions of interstates 10 and 40 could be affected.
