Narrative:

I received WX briefing on known level 5 and 6 thunderstorms from asic at approximately XA30. I asked if tmu would initiate a WX rerte to handle traffic filed over sji via J37. Asic replied a telecon was in place discussing this. At XB15 I had 4 aircraft from the northeast, filed over sji and to the iah/hou area into known WX. The aircraft had WX rerte in the remarks. All 4 requested a rerte around the WX and questioned the rerte. This has happened on multiple occasions this spring using the 'S2K+1' initiative. Callback conversation with reporter revealed the following information: the S2K+1 policy is an FAA/air carrier 'playbook' to address WX rertes. The reporter was advised that this program is based on a 30% WX forecasting probability. The controller's concern is that traffic was rerted by 'central flow' into a known and displayed WX 4 and 5 cell activity area. As the aircraft came into the controller's control area, they wanted further rerouting away from the cell activity that they, as well as the reporter, saw. The controller considers this unnecessary, and potentially dangerous, traffic management policy.

Title: ZTL CTLR CONCERNED WITH NATL TFC MGMNT INITIATIVE (S2K+1) WHEN ACFT ARE RERTED FROM PROPOSED WX PROBS INTO KNOWN WX PROBS.

Narrative: I RECEIVED WX BRIEFING ON KNOWN LEVEL 5 AND 6 TSTMS FROM ASIC AT APPROX XA30. I ASKED IF TMU WOULD INITIATE A WX RERTE TO HANDLE TFC FILED OVER SJI VIA J37. ASIC REPLIED A TELECON WAS IN PLACE DISCUSSING THIS. AT XB15 I HAD 4 ACFT FROM THE NE, FILED OVER SJI AND TO THE IAH/HOU AREA INTO KNOWN WX. THE ACFT HAD WX RERTE IN THE REMARKS. ALL 4 REQUESTED A RERTE AROUND THE WX AND QUESTIONED THE RERTE. THIS HAS HAPPENED ON MULTIPLE OCCASIONS THIS SPRING USING THE 'S2K+1' INITIATIVE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE S2K+1 POLICY IS AN FAA/ACR 'PLAYBOOK' TO ADDRESS WX RERTES. THE RPTR WAS ADVISED THAT THIS PROGRAM IS BASED ON A 30% WX FORECASTING PROBABILITY. THE CTLR'S CONCERN IS THAT TFC WAS RERTED BY 'CENTRAL FLOW' INTO A KNOWN AND DISPLAYED WX 4 AND 5 CELL ACTIVITY AREA. AS THE ACFT CAME INTO THE CTLR'S CTL AREA, THEY WANTED FURTHER REROUTING AWAY FROM THE CELL ACTIVITY THAT THEY, AS WELL AS THE RPTR, SAW. THE CTLR CONSIDERS THIS UNNECESSARY, AND POTENTIALLY DANGEROUS, TFC MGMNT POLICY.
