Narrative:

Our clearance was the tus 6 departure, gbn transition, direct to psp, kayoh 4 arrival to sna. After takeoff, tus departure had us 'deviate as necessary, direct to gbn when able.' there were multiple thunderstorms in the area. We were south of the tus 6 departure corridor on approximately a 280 degree heading to get around the WX. Between FL240 and FL250, ZAB told us to 'squawk 7700, you are in restr airspace.' the controller said a 330 degree heading would get us clear of the restr airspace, but the best I could give them, considering the WX, was a 300 degree heading. Approximately 10 mi later, we were able to go direct gbn, we then advised ZAB center of that. Soon after, ZAB told us to go back to our original squawk code, and we did.
