A FedEx big-rig jackknifed on southbound I-880 in Oakland early this morning and collided with three cars. The good news is no one was seriously hurt. It happened around 1:45 this morning just south of Seventh Street where all lanes were blocked. The CHP got the accident cleared by 4 a.m.

The freeway was slick from the rain during the crash. An investigation is underway to find the official cause.

This morning's storm is causing problems all across the South Bay and in the Santa Cruz Mountains. About 5,000 PG&E customers lost power at one point overnight in parts of San Jose, Los Gatos and the Santa Cruz Mountains.

Driving conditions were also dangerous. The northbound 280 connector ramp to northbound 87 was flooded. The CHP parked a vehicle on the highway to warn drivers.

On Capitol Expressway at Vistapark Drive in San Jose, an Acura SUV ended up on the sidewalk and coming to a rest on a hillside next to an apartment complex.

The driver said it was raining pretty heavily when she started to hydroplane and spun out before leaving the road. A pick-up truck was also involved. Both drivers said they were okay.

Despite today's storms, East Bay water managers don't think Mother Nature will be helping much this season. Our reservoirs are close to 100 percent full, but that's because of last year's rains. This season, East Bay rain levels are only 44 percent of normal. We may need conservation measures again. Water managers will wait until spring to assess the situation. It could get worse as the snowfall in the Sierra is just 20 percent of normal.
