If I read the turnchat log right, there are two barbs. My recollection of barb behavior on this patch level is that they will both come our way, as opposed to ptw which is slightly more random.
Need to decide how to handle the worker as well... If one or both barbs heads in its direction, we could either send it with the settler at the risk of losing both if 2 barbs overwhelm the warrior, or to safety in Noshuret, at the expense of some idle turns until the barb threat is eliminated.
Also, are there future plans for this worker? Noshuret won't need extra food for another 27 turns, but at that point we will need to choose between irrigating to grow beyond size 4, or keeping the size down. The 27 turns are plenty to road over to the BG and do whatever tile improvements the 2nd town takes.
