Multiple power outages were reported in Palo Alto on Tuesday afternoon, including one that impacted 3,380 customers, the Utilities Department said. Thousands more have also been affected by outages in East Palo Alto and at Stanford.

An outgoing power outage has canceled classes Wednesday at Escondido and Nixon elementary schools, according to the Palo Alto Unified School District. Both campuses are in areas served by PG&E.

The largest outage in Palo Alto affected 3,380 customers in the city's Midtown area, where strong winds caused a tree branch to come down on power lines, the Utilities Department said on Twitter at 5 p.m. Service was restored to all but 83 of those customers as of 5:25 p.m.

All but 32 customers had their power restored as of 6:59 p.m. Power was restored for those remaining customers as of 1:37 a.m. Wednesday.

Another Palo Alto outage that affected 577 customers began at 3:12 p.m. in the area of Colorado Avenue and U.S. Highway 101, Palo Alto Utilities said in a tweet. All but 32 customers had service back as of 9:53 p.m. Crews plan to make repairs once the area is deemed safe, according to the Utilities Department. As of 10:30 a.m. Wednesday, the city's outage map showed all customers in the area had service back.

At 3:10 p.m., another outage impacting 54 customers was reported in the Leland Manor neighborhood. The outage was caused by a tree breaking a power pole. The pole was replaced and power was restored at 7:30 p.m.

About an hour earlier, around 2:20 p.m., a downed tree branch struck a power line near Lytton Avenue and Middlefield Road, resulting in a power outage for 207 customers in the Downtown and Crescent Park areas, according to the Utilities Department. As of 2:15 p.m., all but 17 customers had service back. The remaining customers had power back as of shortly before 10 p.m.

An outage in Old Palo Alto impacted 539 customers, some of whom had service restored around 6 p.m. The remaining customers had power back as of 11:01 p.m., the department said.

Another outage that impacted 11 customers in the St. Francis neighborhood started at 7:44 p.m. Tuesday. Those customers are estimated to have service around 2 p.m. Wednesday.

Tuesday's strong gusts also resulted in downed trees, including one that landed on a yard at Hawthorne Avenue and Tasso Street in the Downtown North neighborhood. Power in the 100 block of Tasso was restored as of 6:52 p.m., as the tree brought down power lines, Palo Alto Utilities said.

City crews were removed another large tree that came down in the 700 block of Southampton Drive near Greene Middle School on Tuesday afternoon. Large branches also snapped off, including at New Mayfield and Mimosa lanes in the California Avenue business district.

Thousands of PG&E customers were also without power in East Palo Alto and on the Stanford University campus, according to the utility.

In East Palo Alto, multiple outages affecting more than 7,279 customers began in three waves on Tuesday at 2:10 p.m. 2:25 p.m. and 3:05 p.m.

A possible live wire on University Avenue led East Palo Alto police to block the roadway between Purdue Avenue and Bayfront Expressway, the department shared on Instagram shortly after 5 p.m. Tuesday. The public was advised to take alternate routes due to the road closure, which also prevented access to and from the Dumbarton Bridge via University Avenue, police said. A PG&E crew was called to the scene to address the possible live wire. Police later said University Avenue been reopened as of about 6:30 p.m.

Stanford and surrounding foothill areas had 3,366 customers without power starting at 12:29 p.m. Tuesday. The core campus outage area stretched from the east side of the Oval west to Stanford Avenue. Much of the campus bordering Sand Hill Road to Page Mill Road and bounded by Junipero Serra Boulevard were also without power. Pockets of the interior campus have thus far been spared. Members of the Stanford community impacted by the outage were also directed to the Arrillaga Family Dining Commons or Lagunita Dining for assistance, the university said in an alert.

Stanford and Lucile Packard Children's hospitals and Stanford Shopping Center still had power as of late Tuesday afternoon.

PG&E's outage map showed no estimated restoration time for any of the impacted areas for most of Wednesday. On Thursday morning, no outages were reported at Stanford and pockets of East Palo Alto remained without power.

PG&E notified customers through phone and text message alerts, but the company didn't have an estimate of when power might be restored, owing to the large numbers of crews being pressed into service due to the windy weather.
