Narrative:

The WX at ack at XA00 was reported 1500 ft overcast and 9 mi visibility when I called. The WX at hya (my departure) was MVFR, so I opted to go IFR to ack. There was heavy rain moving in from the west and it started to rain in hya. There was one other C402 IFR to ack ahead of me and one C402 who left ahead of me VFR. The WX at ack began dropping rapidly. The first C402 went missed after shooting the VOR 24 circle to land runway 33, stating dropping visibility due to heavy rain. The VFR C402 called to pick up an IFR clearance. The first IFR C402 was vectored in ahead of me, shot the approach with circle and landed. The WX was being called 3 mi with heavy rain, but the visibility was dropping fast. I shot the approach, saw the runway and commenced the circle. I called tower to tell them I was circling and requested a wide base due to 30 KT winds pushing me wide. Tower approved request. After lining up with the runway 33, I saw visibility had dropped more and felt a go around would be wise. I alerted tower and requested runway heading on departure. Request ok'ed by tower. On my climb out on runway 33, the C402 that had called for a pop-up IFR began to circle for runway 33 by crossing the runway to enter a left downwind. We crossed over the intersection of runway 24 and runway 33. He saw me, but I never saw him. Apparently, tower thought I asked for runway 24 when I meant runway 33.

Title: C402 LNDG ACK EXECUTES WX GAR AND CONFLICTS WITH OTHER ACFT MAKING APCH.

Narrative: THE WX AT ACK AT XA00 WAS RPTED 1500 FT OVCST AND 9 MI VISIBILITY WHEN I CALLED. THE WX AT HYA (MY DEP) WAS MVFR, SO I OPTED TO GO IFR TO ACK. THERE WAS HVY RAIN MOVING IN FROM THE W AND IT STARTED TO RAIN IN HYA. THERE WAS ONE OTHER C402 IFR TO ACK AHEAD OF ME AND ONE C402 WHO LEFT AHEAD OF ME VFR. THE WX AT ACK BEGAN DROPPING RAPIDLY. THE FIRST C402 WENT MISSED AFTER SHOOTING THE VOR 24 CIRCLE TO LAND RWY 33, STATING DROPPING VISIBILITY DUE TO HVY RAIN. THE VFR C402 CALLED TO PICK UP AN IFR CLRNC. THE FIRST IFR C402 WAS VECTORED IN AHEAD OF ME, SHOT THE APCH WITH CIRCLE AND LANDED. THE WX WAS BEING CALLED 3 MI WITH HVY RAIN, BUT THE VISIBILITY WAS DROPPING FAST. I SHOT THE APCH, SAW THE RWY AND COMMENCED THE CIRCLE. I CALLED TWR TO TELL THEM I WAS CIRCLING AND REQUESTED A WIDE BASE DUE TO 30 KT WINDS PUSHING ME WIDE. TWR APPROVED REQUEST. AFTER LINING UP WITH THE RWY 33, I SAW VISIBILITY HAD DROPPED MORE AND FELT A GAR WOULD BE WISE. I ALERTED TWR AND REQUESTED RWY HDG ON DEP. REQUEST OK'ED BY TWR. ON MY CLBOUT ON RWY 33, THE C402 THAT HAD CALLED FOR A POP-UP IFR BEGAN TO CIRCLE FOR RWY 33 BY XING THE RWY TO ENTER A L DOWNWIND. WE CROSSED OVER THE INTXN OF RWY 24 AND RWY 33. HE SAW ME, BUT I NEVER SAW HIM. APPARENTLY, TWR THOUGHT I ASKED FOR RWY 24 WHEN I MEANT RWY 33.
