Northern California drenched by storm

Rain wreaks havoc; snow melt could add to problems.

SAN FRANCISCO — Northern California was drenched by a powerful “Pineapple Express” storm that flooded roadways, forced flight cancellations and caused a rare baseball rainout.

No major problems were reported after the heaviest rain from the “atmospheric river” of subtropical moisture moved through from Hawaii late Friday. But flood warnings and watches remained in effect Saturday for the Sierra Nevada, the Santa Cruz Mountains south of San Francisco and other areas.

Forecasters said runoff from melting snow could add to the chance of rapidly rising streams and rivers.

Police rescued a man who became trapped in a rain-swollen drainage channel near Sacramento, where many roads were flooded. The state capital saw more than 1.17 inches of rain on Friday. Downtown San Francisco saw nearly 2 inches, making for the fourth-wettest April day since records began

Yosemite National Park closed some campgrounds and lodging because of flooding concerns, with the Merced River there expected to peak several feet above flood stage on Saturday.

San Francisco International Airport reported about 150 canceled flights because of the weather and others were delayed.

The opener of the San Francisco Giants-Los Angeles Dodgers weekend series was rained out, the first at the Giants ballpark in 12 years. Saturday’s game was also pushed back by two hours to 3:05 p.m. PDT.

Bodega Bay in Sonoma County received nearly 6 inches of rain — more than the entire rainfall total for March, according to the weather service. County officials said there were no major mudslides in areas stripped bare by last fall’s wildfires.
