Monday’s storm hit KMUN’s transmission tower on Megler Mountain Monday morning.

The damage to the antenna means that station managers are shifting programming to sister station KCPB at 90.9 FM. The regular programming on KCPB will be pre-empted until further notice.

The storm damaged happened between 8 and 10 a.m. Monday at the transmission tower, which is on a ridge above the Washington side of the Astoria-Megler Bridge. The strong winds battering the North Coast blew the antenna off the tower.

A station spokesman said staff are working hard to restore normal broadcasting as soon as possible.
