Classes could be cancelled Monday at Woodrow Wilson High School in Dallas after a power outage Sunday night, according to Dallas ISD.

A truck struck a power line in the 6000 block of Reiger Avenue, cutting power to Wilson High School and Long Middle School. Power was restored to Long Middle School, but it was taking longer to restore at Wilson High School, a district spokesman told News 8.

Dallas ISD hopes to have a decision on cancelling school by late Sunday night, but that call could come Monday morning.
