The power went out around 3 a.m. Thursday morning for neighborhoods north of Herndon between Brawley and Marks.
PG&E says it immediately sent crews to the area to fix the problem.
The power turned back on for most customers just after 4 a.m.
Thousands of Valley residents were without power on Wednesday morning and officials said those outages were related to the rainy weather that was moving through the area at the time. City crews told Action News they would be on-call overnight just in case the rain caused any additional power problems.
However, they say it is still not known if weather is to blame for this most recent outage.
