2009-09 · NASA ASRS report 850201
A B767-300 flight crew received approval for a weather deviation from ATC. The next Controller was made aware of the deviation upon check in but apparently did not note this fact.
During cruise; FL360; asked Minneapolis Center for clearance to deviate right of course for a thunderstorm approx 80NM in front of us. Received clearance to deviate; followed by a frequency change with instructions to inform them of our deviation. The Captain checked in and informed Center of our deviation right (north) of course for weather. Center acknowledged our check in. Soon after; Center called out the thunderstorm ahead of us that we were already deviating for. The Captain again acknowledged and said we were deviating. Maybe five or ten minutes after that; Center called and said we were north of course. The Captain said that we were because we were deviating to the right because of a thunderstorm. Center then asked if we received clearance to deviate and we said yes; from the previous controller. She apparently then called the previous controller and then told us that the previous controller had failed to inform her that we were deviating. After passing the thunderstorm we returned to course with no further incident. I never felt that we had deviated from an ATC clearance; but I was left with the impression from the controller that she thought we had until she spoke to the previous controller.
When I checked in with this Controller I told her we were right or course for weather. A couple minutes later; Controller asked why we were right of course. I told her I said right of course for weather when I checked on. No reply from Controller about that. We double-checked we were cleared right of course for weather and all normal after that.
