Not surprisingly, the wettest days occurred when tropical cyclone made landfall, like in 1945 with Hurricane #5. 1949 happened a few days after Hurricane #10 made landfall. Some of the heaviest rains occurred in fall or winter. The date that stands out is 1929 as there was massive flooding in April and May of that year. Flooding is known to occur in January like 1891, 1979, 1980, and 1989.
