SAN DIEGO (FOX 5/KUSI) -- Power was restored to all San Diego Gas & Electric customers Wednesday after thousands were left without electricity since the beginning of the week. The power outages were due to public safety power shutoffs that started on Monday to prevent the risk of wildfires during a Red Flag Warning. "The last three days brought our region extreme wildfire conditions and the strongest Santa Ana wind event in years, bringing wind speeds that approached and, in some cases, exceeded hurricane-strength levels," SDG&E said in a news release. Can San Diegans who lost power get reimbursed for spoiled groceries? Winds reached the 99th percentile in wind speeds ever recorded at more than 100 of SDG&E's weather monitoring stations, the utility company said, adding that the highest gust measured was at 95 miles per hour. SDG&E says around 50,000 customers did not have power Monday and Tuesday. Twelve community resource centers offering services such as Wi-Fi, food and phone and medical device charging were offered to impacted customers. Once weather conditions were deemed safe, crews inspected power lines to make sure they were safe to operate.
