The first significant rainstorm in five months was due to arrive in Orange County this morning and could dump up to three-quarters of an inch of rain in some cities.
"It'll be a good time to grab your umbrellas and raincoats," said Mark Mulholland, a meteorologist with WeatherData Inc., which provides forecasts for The Times.
But the showers shouldn't linger. They are expected to dissipate later in the day, Mulholland said.
"It's a one-day event," he said.
The storm is the tail end of a cold front that swept through northern and central California on Tuesday. It helped firefighters douse a 4,430-acre wildfire in steep terrain near Big Sur but caused major power outages and slick highways, leading to traffic accidents in the San Francisco Bay area.
The last significant rainfall was May 24, when a rainstorm--unusual for that time of year--drenched areas in South County, causing several major traffic pile-ups.
