Potential significant coastal storm Sunday night into Tuesday

NOAA reports that confidence is increasing that there will be a significant coastal storm bringing heavy precipitation, strong winds, and coastal flooding to the Tri-state area Sunday night into Tuesday. 
 
Potential exists for a period of accumulating heavy wet snow across the hills of NE NJ, Lower Hudson Valley and SW CT during the Sunday night into Tuesday morning time frame.
 
The following is a detailed breakdown of potential hazards and impacts from this storm:

Strong Wind

  • Moderate potential for easterly winds of 25 to 35 mph with gusts to 50+ mph along the coast during the Sun night to Monday night time frame.
  • Low potential for wind gusts of 60+ mph. 
  • Tree damage and power outages possible.
Rainfall/Flooding
  • Potential for rainfall of 1 to 3 inches with locally higher amounts Sunday Night into Tuesday.
  • Threat for minor urban and small stream flooding if high end rainfall amounts are realized. 
  • Rises on larger rivers are likely...but at this point the threat for minor flooding of adjacent areas is slight. 

Snow/Wintry Mix

  • Potential exists for a period of accumulating heavy wet snow across the hills of NE NJ, Lower Hudson Valley and SW CT during the Sunday night into Tuesday morning time frame.
Coastal Flooding
  • Moderate potential for minor coastal flooding during the Monday and Tuesdaymorning high tides, with potential for locally moderate coastal flooding if peak surge coincides with high tides. The highest threat for coastal impacts will be for flood prone locales along the south shore bays of LI/NYC...eastern bays of LI...lower NY/NJ Harbor...and western LI Sound. 
  • High surf will bring potential for dune erosion and localized washovers along the Atlantic Ocean beachfront Mon into Tue.
Marine Hazards
  • East to Northeast Gales likely Sunday night into Monday night on all waters.
  • Potential for storm force gusts on the ocean and Eastern LI Sound.
  • Seas could build to 15 to 20 ft on the ocean waters Mon into Mon Night...and 5 to 8 ft Sun Night into Mon Night on Long Island Sound.
Uncertainty
  • There is model spread in timing and track of the storm this far out, which will affect rainfall timing and amounts, wintry precipitation potential, and coastal flood potential.
