SAN DIEGO (FOX 5/KUSI) — San Diegans are bracing for potential public safety power shutoffs Tuesday as a new round of strong Santa Ana winds are expected to develop, setting the stage for potentially critical fire danger in the county. San Diego Gas & Electric says it could begin cutting power in high-risk areas as early as noon and last until early Friday evening. A Red Flag Warning signaling conditions ideal for rapid fire spread is set to go into effect at 4 a.m. on Wednesday. More than 64,000 customers in San Diego's backcountry and exurbs were alerted to potential service disruptions over the weekend — nearly a month after the last round of public safety power shutoffs during risky fire conditions.

(San Diego Gas & Electric) Similarly with the last event, wind speeds are anticipated to reach speeds between 25 to 35 miles per hour with individual gusts hitting up to 55 miles per hour. However, since then, fuels for wildfires have continued to dry out, given an absence of any significant rainfall. Should this pattern hold, fire officials say this bout of Santa Anas could serve as a sign of what might be in store for the rest of the year. "We truly are in a fire year," Cal Fire San Diego Captain Mike Cornette said. "Years in the past where we haven't had any rain, we've had wind and dry conditions and we've had large fires almost every month in this county." With this wind event, fire officials encourage people regardless of whether they are in a high-risk area to monitor conditions and emergency notifications for situational awareness. They also urge people to be proactive in the event a wildfire sparks nearby by alerting fire officials and getting to safety. Community resource centers will become available if any shutoffs are carried out to give those impacted access to electricity to charge phones and other devices, such as medical tools. The centers also have Wi-Fi connectivity, water, ice and snacks, among other resources. Can San Diegans who lost power get reimbursed for spoiled groceries? A map of community resource centers will become available on SDG&E's website as soon as they are launched. San Diegans are similarly advised to prepare for the possibility of any outages — both precautionary and unplanned — and generally unsafe conditions with the onset of this Santa Ana wind event Tuesday afternoon. This includes avoiding driving through areas with strong winds, especially those with high profile vehicles, and taking steps to secure loose outdoor items that could interact with power lines in the event they are blown away.
