A fourth outage was reported around 9 p.m. Monday and was affecting 1,710 residents, according to Edison’s website.

Some residents had power returned to their home around 9:30 p.m. Monday, but Edison reported more than 1,000 people were still affected by blackouts as of The Signal’s press deadline.

Power was expected to be restored to most residents by 7 a.m. Tuesday, and the causes of the outages were not immediately available.
