ZLA CTLR ADVISES B737-500 FLT CREW THAT THEY HAVE ENTERED A RESTR AREA AFTER APPROVED WX DEV; AND TO SQUAWK 7700.

Narrative

APPROX 50 MI W OF DAGGETT (DAG) ON AN EASTERLY HEADING; OUR RADAR SHOWED WX AT DAG AND SLIGHTLY N AND S; SO WE REQUESTED DEV TO THE L (N) OFF COURSE AROUND IT. ZLA CHKED; BUT WAS UNABLE TO APPROVE IT DUE TO RESTR AREAS N OF DAD BEING HOT. CONTINUING EBOUND; WE THEN REQUESTED TO CIRCUMVENT THE WX S NEAR OR JUST S OF HECTOR (HEC). DEVIATE AS NECESSARY WAS APPROVED; AND WE HAD TO TURN ALMOST DUE S TO GET AROUND THE FIRST CELL THAT WAS W OF HEC. AS WE TURNED EASTERLY; AIMING JUST S OF HEC FOR WX AVOIDANCE; CTR SAID TO TURN L TO 030 DEGS; BUT WE WERE UNABLE DUE TO WX. HE FINALLY SAID 'COME R; DO WHAT YOU NEED TO DO; MAYBE A 360 DEGS. YOU'RE IN THE HOT RESTR AREA; SQUAWK 7700.' IN FURTHER DISCUSSION WITH ATC DURING OUR TURN R; WE TURNED 180 DEGS AND HEADED W; AWAY FROM THE RESTR AREA AND WX; EVENTUALLY GETTING VECTORS BACK AROUND TO THE N OF DAG; OUR REQUEST IN THE FIRST PLACE. SUPPLEMENTAL INFO FROM ACN 591957: AS WE PROCEEDED AROUND THE S OF THE WX THE CTLR SEEMED CONCERNED OVER OUR COURSE HE ASKED IF WE COULD TURN TO 030 DEGS AND WE SAID NO 050 DEGS WAS BEST WE COULD DO. HE SAID MAKE A R TURN. AFTER WE DID; HE SEEMED CONFUSED AND CONCERNED AGAIN AND SAID WE WERE FLYING INTO A HOT RESTR AREA. HE WOULD NOT LET US GO STRAIGHT. WE COULDN'T GO L; SO WE WENT R; AT HIS INSTRUCTIONS. HE SAID TO SQUAWK 7700 (WE DID NOT DECLARE AN EMER). HE THEN TOOK US AROUND THE N SIDE OF WX WHERE WE WERE GOING IN THE FIRST PLACE. THIS CTLR SEEMED UNABLE TO DEAL WITH THE NORMAL OCCURRENCE OF WX DEVS; AND HIS INSTRUCTIONS PUT US IN HARM'S WAY.
