I'm not referring to frequency but the water content in each storm. There are a lot of sources, but here is a preliminary data report that was put together by NOAA[1]. There is commentary by scientists at NOAA[2].
Overall this isn't rocket science. You have warmer temperatures over the ocean, which yields more water in the air to get caught up in passing hurricanes. The net result is more rainfall when it hits land. It is what it is.
