Rialto Power Outage Today: Storm-Related Disruption Claims Not Confirmed on November 10
Reports claiming that stormy weather has caused widespread power outages and infrastructure disruptions in Rialto, California, on November 10, 2026, have not been independently confirmed.
The claims appear to combine information from a separate Southern California incident that occurred in September. On September 6, outages in Arcadia disrupted several traffic signals and affected the city’s police department’s non-emergency telephone and business lines during weather associated with Hurricane Marie.
That incident was reported in Arcadia, not Rialto.
What Happened During the September Storm?
Hurricane Marie generated tropical moisture, rain, gusty winds and hazardous coastal conditions across parts of Southern California in early September.
During the September 6 outage, Arcadia experienced disruptions affecting traffic signals and police administrative telephone services. Emergency 911 calls remained operational, with Monrovia Police assisting with call answering and dispatch arrangements.
Southern California Edison said at the time that it had not experienced a significant increase in outages across its service territory as a result of the weather.
Current Rialto Power Outage Status
Available city-level outage information showed no customers without power in Rialto in the latest reported update reviewed for this article.
Southern California Edison’s November 10 public-safety power-shutoff dashboard also listed San Bernardino County under normal conditions, indicating that a weather-related safety shutoff was not expected at that time.
These figures do not rule out every brief or local interruption, but they do not support claims of a widespread storm-related outage in Rialto.
Safety Guidance for Residents
Residents who experience an electricity interruption should check their utility’s official outage information for updates.
Anyone encountering a fallen power line should stay well away and contact emergency services. Drivers should treat traffic signals that are completely dark as four-way stops and proceed carefully.
There is currently no verified basis for describing Hurricane Marie as the cause of a new Rialto power outage on November 10, 2026.
