A warm front ahead of a developing coastal low pressure system positions itself over the area late on December 17th and into December 18th. As the low pressure intensified and approached, significant amounts of moisture focused along the warm front ahead of the coastal low resulting in widespread areas of heavy rainfall that occurred over a 12-18 hour period. PWATs were 1.5-1.7 inches which were near record values. A widespread 2-5 inches of rain fell over the area. This resulted in many areas of flash flooding as well as significant rises in rivers.
