After the storms this evening we found a puddle on 3rd floor in the stairwell behind reference. I’ve placed a wet floor caution sign on the stairwell door and we will attempt to snag the cleaners as we leave at close and alert them. It should not pose any danger to patrons as they should not be entering the stairwell anyway and it is far from any book ranges. There is a slight possibility the puddle could grow larger if rains return during the night but if the cleaners can mop it while here I think it will be okay.
