NAPA, Calif. (AP) -- This is what Associated Press reporters on the scene are learning following the largest earthquake to hit the San Francisco Bay Area in 25 years:
5:43 p.m. PDT
State and local roads leading to wineries south of Napa, around the community of Carneros, we're closer to the quake's suspected origin and showed more damage than elsewhere. By the middle of the afternoon, road crews had patched a section of state Highway 121 where the roadbed had shifted, cracking open the surface. Nearby, crews repaired a local road where the roadbed had dropped several inches.
Off that road, vintner Richard Ward of Saintsbury winery oversaw workers righting giant toppled barrels and rescuing a 500-pound grape de-stemmer that the quake had thrown to the ground.
"That's what happens when you're a mile from the epicenter," he said, turning to point toward hills where the quake apparently started.
Ward lost 300 to 400 bottles in the winery's basement. The grape harvest was supposed to have started overnight tonight, but would now be pushed off a few days, he said. Had the harvest started last night, the quake would have caught the workers in the wine buildings, with the heavy barrels, when it struck, Ward said.
5:23 p.m. PDT
Mark Ghilarducci, director of the California Governor's Office of Emergency Services, said at a news conference late Sunday afternoon that the situation had stabilized.
By midday, officials had a good sense that the fires were out and power was starting to be restored. "While it was bad, it wasn't as bad as it could be and it was very manageable from a regional perspective," he said.
Ghilarducci said about 90 to 100 homes were deemed not habitable. He said the next step was to continue damage assessments and get a cost estimate for potential federal assistance.
Aftershocks were expected to continue for several weeks, though State Geologist John Parrish said they would decrease in magnitude and it was unlikely that there would be a large follow-up earthquake. Still, he warned people to be careful because buildings that were damaged by the quake were now more susceptible to collapse from aftershocks.

Pacific Gas and Electric has lowered the pressure on its Sonoma-to-Napa gas line and is monitoring all gas outlets for leaks, spokesman Jeff Smith said. The company has so far received 439 complaint calls about gas odors and has cut off gas to about 20 customers because of damaged equipment, Smith said. Anyone with concerns about a gas leak may call the company at 800-743-5002, he said.
As of 5 p.m., about 7,300 electricity customers are without power, he said.
3:33 p.m. PDT
Pacific Gas and Electric Co. has reduced the number of customers without power to about 17,000, spokesman Jeff Smith said. Right after the earthquake hit 12 hours ago, about 70,000 people were without power, he said.
2:46 p.m. PDT
Pacific Gas and Electric Co. is working to restore power to 30,000 customers after the earthquake, spokesman Jeff Smith said.
There have been "no reports of significant damage" to the company's equipment, Smith said. Crews are continuing to assess the situation, he added.
If customers smell gas or experience an emergency, they should call the company immediately, Smith said.
Customers should not try to turn their gas on themselves, he said. Customers should call Pacific Gas and Electric "to get your gas back on" to avoid a potentially dangerous situation, Smith said.
2:25 p.m. PDT
The California Department of Transportation has inspected San Francisco Bay Area state highways and structures and says all damage appears to be minor.
The agency says bridges and roadways are open and safe for travel.
2:14 p.m. PDT
All Napa Valley Unified School District campuses will be closed Monday. Justin Siena High School will also be closed.
2:14 p.m. PDT
U.S. Sen. Barbara Boxer, D-Calif., said in a statement that she will be sending staffers to hard-hit Napa on Monday and said: "I will be talking to local officials about how we can help ensure that residents, businesses and communities have the resources they need to recover and rebuild."
2:14 p.m. PDT
Queen of the Valley Medical Center in Napa, which treated 120 people, has some damage from the earthquake. That included burst pipes in a non-patient area, ceiling tiles falling off in office areas and minor structural damage to an outbuilding.
Spokeswoman Vanessa DeGier said: "We are open 24 hours a day and so some of our staff did sustain some injuries," which she characterized as minor.
