Although it's not known yet how many Fredericksburg residents are without power, at least one transformer blew in the 800 block of Charlotte Street this afternoon.

Fredericksburg Deputy Fire Chief Mike Jones said they got a report of a second blown transformer, but crews were unable to find it.

Dominion Virginia Power has been notified. All of Cobblestone Apartments are without power and other parts of Lafayette Boulevard.

Dominion said there is a tree on a power line that is causing some of the outages. The utility company expects power to return between 6 p.m. to 8 p.m.
