We thoroughly briefed all applicable departure procedures after requesting zip 1 departure, due to WX, ndbs did not point accurately after takeoff. We had tuned and idented prior to takeoff and they pointed correctly as we initiated the departure roll. ATIS did not reflect station passage. We continued normally, but this could have been a serious problem.
