A wide area of San Francisco has been hit by a power outage.

The blackout hit at midmorning Friday in the Financial District and other areas.

The Bay Area Rapid Transit tweeted that its downtown Montgomery Station is closed due to the outage.

The San Francisco Chronicle says (http://bit.ly/2pN3o6b ) the outage is also affecting the Presidio, and KRON-TV reports the outage stretches to the Marina/Cow Hollow area.

A call seeking comment from Pacific Gas & Electric was not immediately returned.
