Cold Storm Bears Down With Possibility of Much Need Rain

A cold Canadian storm is expected to affect Friday commutes while bringing the threat of thunder, hail and water spouts off the coast.

A cold, winter-like storm system out of British Columbia bore down on Southern California today, bringing a threat of showers from this afternoon through Friday evening, along with a slight chance of thunderstorms.

If thunderstorms materialize, they’ll be capable of producing heavy downpours and small hail, according to a National Weather Service statement, which said thunderstorms could affect rush-hour commutes starting this evening.

Conditions will also favor isolated waterspouts in coastal waters, the statement said.

Rainfall amounts will vary considerably given the showery nature of this system, and some areas may experience no precipitation whatsoever, the statement said, adding that in general, rainfall amounts will be less than a quarter-inch. However, if thunderstorms develop, a half-inch of rain may result in certain areas, and minor mud and debris flows could occur in burn areas, it said.

In the San Gabriel Mountains, the snow level is expected to fall to 6,000 feet by late this afternoon, later dropping even further, down to 4,500 feet.
