Narrative:
WX was starting to impact our airspace and I was reassigned to another sector as a handoff man because our area was changing airspace. The sector I was handing off for I only had been checked out for 3 months and my total radar time since checking out was about 2 hours. When I got to the sector the radar controller had many aircraft deviating around WX and the sector was out of control. I plugged in right away but wasn't able to get a briefing due to the radar man being behind the problem. All that I could do was try to help pick up the pieces as we went along. We had many aircraft in our airspace west/O handoff. We also had some of our own aircraft in other sectors airspace west/O handoffs, and coordination was made to another sector to miss traffic etc. During my exchanges with other sectors, my phraseology went to pot and at times used profane language. Within this time we had a loss of sep.

Title: LOSS OF SEPARARTION OCCURRED BETWEEN ACFT DUE TO SECTOR OVERLOAD DURING AIRSPACE CONFIGURATION CHANGE.
Narrative: WX WAS STARTING TO IMPACT OUR AIRSPACE AND I WAS REASSIGNED TO ANOTHER SECTOR AS A HDOF MAN BECAUSE OUR AREA WAS CHANGING AIRSPACE. THE SECTOR I WAS HANDING OFF FOR I ONLY HAD BEEN CHKED OUT FOR 3 MONTHS AND MY TOTAL RADAR TIME SINCE CHKING OUT WAS ABOUT 2 HRS. WHEN I GOT TO THE SECTOR THE RADAR CTLR HAD MANY ACFT DEVIATING AROUND WX AND THE SECTOR WAS OUT OF CTL. I PLUGGED IN RIGHT AWAY BUT WASN'T ABLE TO GET A BRIEFING DUE TO THE RADAR MAN BEING BEHIND THE PROB. ALL THAT I COULD DO WAS TRY TO HELP PICK UP THE PIECES AS WE WENT ALONG. WE HAD MANY ACFT IN OUR AIRSPACE W/O HDOF. WE ALSO HAD SOME OF OUR OWN ACFT IN OTHER SECTORS AIRSPACE W/O HDOFS, AND COORD WAS MADE TO ANOTHER SECTOR TO MISS TFC ETC. DURING MY EXCHANGES WITH OTHER SECTORS, MY PHRASEOLOGY WENT TO POT AND AT TIMES USED PROFANE LANGUAGE. WITHIN THIS TIME WE HAD A LOSS OF SEP.
