A coastal storm will bring a multi-faceted set of hazards to the region. The headlines depict the current thinking. Key factors include:

1.) Rain-snow line and level of elevation for heaviest snow in the Winter Storm Warning area along with any extent of wet snow damage that could be enhanced by strong to damaging winds in these areas. Same is true in the Winter Weather Advisory area.
2.) Extent of flooding from heavy rainfall and how widespread the heaviest rainfall is across lower elevations of Southern New England
3.) How widespread strong to damaging winds are in the High Wind Warning and Wind Advisory areas.
4.) Extent of coastal flooding that will depend on the strong winds and how close those winds are to the high tide cycles
5.) Extent of rainfall and river flooding as well as any flooding of urban and poor drainage areas if heavy rain falls over a short enough period of time
