Yeah I made this list of rain storms that I would take over most snow storms (outside of the 20+ inch snowstorms, those are in their own category.)
This is in chronological order (if I had to rank them by severity I think I'd put Dec 1992 first, for its longevity, sustained high winds, rainfall and widespread flooding.)
1. Hurricane Gloria (1985)
2. November severe weather event (1989)
3. Hurricane Bob (1991)
4. Perfect Storm (1991)
5. December noreaster (1992)
6. July Hailstorm (1994)
7. Tropical Storm Bertha (1996)
8. May Derecho (1998)
9. Labor Day Tornado (1998)- an F2 only 2 miles from my house!
10. Hurricane Floyd (1999)
11. October rainstorms (2005)- rainiest month EVER here, around 20" of rain!
12. March noreaster (2010)
13. September derecho/tornadoes (2010)
14. August rainstorm (2011)- rainiest single storm here, around 10" of rain!
15. Hurricane Irene (2011)
16. Hurricane Sandy (2012)
There's probably a lot more I missed, but these come to mind right away.
edit- I added some severe wx events that came to mind.
