Narrative

LOCATION: B24; BTWN LYNUS AND CHAMP. FLYING ENRTE FROM PHL TO SJU ON B24 BTWN LYNUS AND CHAMP WE NEEDED TO DEVIATE TO THE W AROUND A LONG LINE OF TSTMS WHILE FLYING AT FL290. INITIALLY WE ASKED FOR FL330; AS THIS WOULD HAVE PLACED US OVER THE WX. FL 330 WAS UNAVAILABLE ACCORDING TO NY COMMERCIAL RADIO AND WE THEN ASKED FOR DEV W OF COURSE; AND THEN LATER ASKED AGAIN FOR FL330. WE WERE TOLD TO CONTACT NY ON HF AND DID SO. WE INFORMED NY ON HF OF OUR DEV TO THE W FOR WX AND THEN LATER ASKED FOR DIRECT DOWNT. WE ALSO REQUESTED FL330 AGAIN WITH NY ON HF. WE GAVE NY OUR POS RPT; AFTER BEING CLRED DIRECT HUBER; IN LATITUDE/LONGITUDE -- FOR PRESENT POS -- AND GAVE ESTIMATES FOR HUBER AND HOLMA; THE NEXT 2 POINTS ON OUR RTE OF FLT. NY ASKED US TO CONFIRM OUR POS AT THIS TIME; WHICH WE DID AGAIN WITH LATITUDE/LONGITUDE. HE ALSO ASKED US WHO GAVE US CLRNC TO DEVIATE; AND WE TOLD HIM THE CLRNC HAD BEEN GIVEN BY A PREVIOUS CTLR; NAMELY NY COMMERCIAL RADIO ON FREQ 129.9. WE RPTED THE FACT WE WERE DEVIATING W OF COURSE FOR WX TO EACH CTLR WE SPOKE WITH AFTER OUR INITIAL CLRNC WAS GIVEN TO US ON 129.9. EVIDENTLY THE CTLR ON THE HF FREQ WAS UNAWARE OF OUR DEV. HE MADE NO REF TO IT AFTER ASKING US WHO GAVE US CLRNC TO DEVIATE.
