Narrative:

While flying the heatt 5 arrival into miami on the vrb 162 degree radial, we observed some thunderstorms ahead and to the ese. We requested a right turn off the arrival to deviation around the WX that we were about to encounter. ZMA granted our request for a turn to the right. ZMA also requested a speed of 320 KTS or greater and an expedited descent through FL190 as we were on our way to 16000 ft. The first officer acknowledged all clrncs to ZMA. The right turn that we made ended up being a heading of 240 degrees to avoid the thunderstorms. We were then handed off to mia approach at which time we received an RA on our TCASII. Approach control asked who gave us the approval for a right turn and the first officer replied 'ZMA approved our deviation.' captain and first officer observed traffic in a climb to our left (an air carrier jet). As we were leveling at 16000 ft, we received a TCASII RA of 'climb.' the captain disengaged the autoplt, but didn't take any evasive action because he had the traffic in sight and felt there would not be a conflict. TCASII came back with 'monitor vertical speed,' and 'clear of conflict.' first officer told approach control that traffic was in sight and they replied 'maintain visual separation.' mia approach told us there was 'no problem.' we turned left 180 degrees and then 120 degrees to rejoin the arrival as requested by mia approach. I think that what led to the problem was the fact that we were flying very fast per ZMA and flew into the departure corridor from mia airport. Maybe there was a loss of communication between ZMA and mia approach as it seems approach didn't realize we were in an unexpected place. By 'fast,' I am referring to what seemed like a busy situation. The frequency was very congested also. Supplemental information from acn 538253: ZMA had previously requested 320 KTS or greater (high noise level in cockpit). Center then cleared us to 16000 ft and expedite through FL190 and report passing through FL190, fly heading 180 degrees when able. We turned to a 240 degree heading to avoid the thunderstorms. First officer informed approach that traffic was in sight and approach replied 'maintain visual separation.'

Title: B727 FLC RECEIVE TCASII ALERT WHEN DEVIATING FOR WX, TURNING BEYOND COORD HDG AND CHANGED FREQ FROM ZMA TO MIA APCH.

Narrative: WHILE FLYING THE HEATT 5 ARR INTO MIAMI ON THE VRB 162 DEG RADIAL, WE OBSERVED SOME TSTMS AHEAD AND TO THE ESE. WE REQUESTED A R TURN OFF THE ARR TO DEV AROUND THE WX THAT WE WERE ABOUT TO ENCOUNTER. ZMA GRANTED OUR REQUEST FOR A TURN TO THE R. ZMA ALSO REQUESTED A SPD OF 320 KTS OR GREATER AND AN EXPEDITED DSCNT THROUGH FL190 AS WE WERE ON OUR WAY TO 16000 FT. THE FO ACKNOWLEDGED ALL CLRNCS TO ZMA. THE R TURN THAT WE MADE ENDED UP BEING A HDG OF 240 DEGS TO AVOID THE TSTMS. WE WERE THEN HANDED OFF TO MIA APCH AT WHICH TIME WE RECEIVED AN RA ON OUR TCASII. APCH CTL ASKED WHO GAVE US THE APPROVAL FOR A R TURN AND THE FO REPLIED 'ZMA APPROVED OUR DEV.' CAPT AND FO OBSERVED TFC IN A CLB TO OUR L (AN ACR JET). AS WE WERE LEVELING AT 16000 FT, WE RECEIVED A TCASII RA OF 'CLB.' THE CAPT DISENGAGED THE AUTOPLT, BUT DIDN'T TAKE ANY EVASIVE ACTION BECAUSE HE HAD THE TFC IN SIGHT AND FELT THERE WOULD NOT BE A CONFLICT. TCASII CAME BACK WITH 'MONITOR VERT SPD,' AND 'CLR OF CONFLICT.' FO TOLD APCH CTL THAT TFC WAS IN SIGHT AND THEY REPLIED 'MAINTAIN VISUAL SEPARATION.' MIA APCH TOLD US THERE WAS 'NO PROB.' WE TURNED L 180 DEGS AND THEN 120 DEGS TO REJOIN THE ARR AS REQUESTED BY MIA APCH. I THINK THAT WHAT LED TO THE PROB WAS THE FACT THAT WE WERE FLYING VERY FAST PER ZMA AND FLEW INTO THE DEP CORRIDOR FROM MIA ARPT. MAYBE THERE WAS A LOSS OF COM BTWN ZMA AND MIA APCH AS IT SEEMS APCH DIDN'T REALIZE WE WERE IN AN UNEXPECTED PLACE. BY 'FAST,' I AM REFERRING TO WHAT SEEMED LIKE A BUSY SIT. THE FREQ WAS VERY CONGESTED ALSO. SUPPLEMENTAL INFO FROM ACN 538253: ZMA HAD PREVIOUSLY REQUESTED 320 KTS OR GREATER (HIGH NOISE LEVEL IN COCKPIT). CTR THEN CLRED US TO 16000 FT AND EXPEDITE THROUGH FL190 AND RPT PASSING THROUGH FL190, FLY HDG 180 DEGS WHEN ABLE. WE TURNED TO A 240 DEG HDG TO AVOID THE TSTMS. FO INFORMED APCH THAT TFC WAS IN SIGHT AND APCH REPLIED 'MAINTAIN VISUAL SEPARATION.'
