Rapid snowmelt from a few day period of well above normal temperatures focused on the 11-13th of April resulted in moderate to locally major flooding through much of the James River Basin. Some areas north of I-90 lost between 2 to 5 inches of snow water equivalent (SWE) from the first to second week of April, but antecedent drought conditions resulted in only a percentage of this water actually making it into the river system.
