Narrative:

Air carrier X departing mia, climbed to 7000 ft. Air carrier Y inbound to mia was descending out of 9000 ft for 8000 ft. Controller used anticipated separation and climbed air carrier X. Air carrier Y was deviating around WX. The TCASII went off on both aircraft. Air carrier X climbed to 7300 ft and then descended. Air carrier Y descended to 8400 ft and then climbed up to 9000 ft. The controller observed the situation and also took action by descending air carrier X. There was no loss of separation. During bad WX, pilots and controllers should be more aware of WX deviations.

Original NASA ASRS Text

Title: ACR X CLB TO SAME ALT, ACR Y DSCNT TO SAME ALT RECEIVED TCASII RA'S, EVASIVE ACTION TAKEN.

Narrative: ACR X DEPARTING MIA, CLBED TO 7000 FT. ACR Y INBOUND TO MIA WAS DSNDING OUT OF 9000 FT FOR 8000 FT. CTLR USED ANTICIPATED SEPARATION AND CLBED ACR X. ACR Y WAS DEVIATING AROUND WX. THE TCASII WENT OFF ON BOTH ACFT. ACR X CLBED TO 7300 FT AND THEN DSNDED. ACR Y DSNDED TO 8400 FT AND THEN CLBED UP TO 9000 FT. THE CTLR OBSERVED THE SIT AND ALSO TOOK ACTION BY DSNDING ACR X. THERE WAS NO LOSS OF SEPARATION. DURING BAD WX, PLTS AND CTLRS SHOULD BE MORE AWARE OF WX DEVS.
