Per a NWS Consult –
 
Overview:
 
As high pressure remains perched well to the north…a series of low pressure systems will pass to our South through Sunday. This will result in persistent wet weather and gusty winds. Temperatures will average 20 to 25 degrees below normal over the next several days.
 
Precipitation:
 
Rainfall has overspread the region and will continue through the early hours on Friday. Rainfall totals of 1 to 1.5 inches are possible in New York City during this time. As the rain is predicted to fall over a prolonged period, there is no widespread rainfall flooding concerns at this time. However, as we are in the Autumn season, areas of the City where leaves have begun to fall from trees and accumulate alongside roadways and catch basins may experience some localized nuisance-type minor flooding conditions.
 
There is a chance of some light rainfall on Friday in between the passage of both storm systems.
 
Rainfall will pick up in intensity and may be heavy at times on Saturday. Rainfall forecasts are currently calling for approximately 1 to 3 inches of rain for the NYC area. The potential for rainfall flooding exists and will be closely monitored as we approach the second storm period on Saturday. 
 
Winds:
 
Northeast winds will increase during the day as the first storm system intensifies. Sustained winds of 15 to 25 MPH with some gusts to 30 MPH are expected through the overnight and into Friday. The winds will die down midday on Friday, but are expected to intensify again as the second storm system moves closer to the area.
 
Coastal Flooding:
 
There are some coastal flooding concerns associated with this Nor’easter. A high astronomical tide cycle associated with a new moon, coupled with the persistent northeasterly winds will result in tidal piling that will cause tidal departures of 2 to 2-1/4 feet above normal during periods of high tide on Friday. These tidal departures will result in minor to moderate coastal flooding along immediate coastal areas. The tidal departures will lessen late Friday night, however coastal flooding will become a threat again as the second Nor’easter arrives on Saturday. It is still too early to forecast tidal departures for the Saturday event.
 
Products:
 
A Coastal Flood Watch remains in effect for New York City from late tonight through Friday morning. There are currently no other products in effect for City. 
 
YWN Watch Command will continue to monitor meteorological conditions and additional forecast updates will be issued as necessary.
