Narrative:
While working final approach radar; visual approachs runways 18L and 18R; A320 was cleared for visual approach to runway 18R and told simultaneous approachs were in progress. Meanwhile; a B737 was being vectored 240 degree heading to runway 18L final approach course; descending to 4000 ft. This pilot did not see the airport; so I turned him to a 180 degree heading about 4 mi from runway 18L localizer. Aircraft was rather slow to turn; and was approximately 3 mi east of the A320 when pilot of B737 called airport in sight. He was then cleared for the visual approach to runway 18L; with simultaneous approachs. B737 continued sswbound and crossed the runway 18L localizer abeam A320 on runway 18R localizer. Conflict alert sounded and was manually silenced; whereby I notified the TRACON supervisor of the conflict alert. When I asked later about the separation; the supervisor said I had divergence until the B737 had the airport in sight.

Title: TPA CTLR DESCRIBED CONFLICT BTWN VISUAL APCHS ON RWY 18L AND RWY 18R WHEN TFC FOR RWY 18L OVERFLEW TURN TO FINAL.
Narrative: WHILE WORKING FINAL APCH RADAR; VISUAL APCHS RWYS 18L AND 18R; A320 WAS CLRED FOR VISUAL APCH TO RWY 18R AND TOLD SIMULTANEOUS APCHS WERE IN PROGRESS. MEANWHILE; A B737 WAS BEING VECTORED 240 DEG HDG TO RWY 18L FINAL APCH COURSE; DSNDING TO 4000 FT. THIS PLT DID NOT SEE THE ARPT; SO I TURNED HIM TO A 180 DEG HDG ABOUT 4 MI FROM RWY 18L LOC. ACFT WAS RATHER SLOW TO TURN; AND WAS APPROX 3 MI E OF THE A320 WHEN PLT OF B737 CALLED ARPT IN SIGHT. HE WAS THEN CLRED FOR THE VISUAL APCH TO RWY 18L; WITH SIMULTANEOUS APCHS. B737 CONTINUED SSWBOUND AND CROSSED THE RWY 18L LOC ABEAM A320 ON RWY 18R LOC. CONFLICT ALERT SOUNDED AND WAS MANUALLY SILENCED; WHEREBY I NOTIFIED THE TRACON SUPVR OF THE CONFLICT ALERT. WHEN I ASKED LATER ABOUT THE SEPARATION; THE SUPVR SAID I HAD DIVERGENCE UNTIL THE B737 HAD THE ARPT IN SIGHT.
