Post-Tropical Storm Hermine Remains A Threat For the Coastal Northeast! (credit: NWS Upton, New York)

DISCUSSION: As of late this evening, the forecast (i.e., the projected track for what still remains to be Post-Tropical Storm Hermine) has changed somewhat from earlier forecast thinking for Hermine.  The main difference is characterized by the most likely future track of this system to take more of a westerly track than previously expected over the past 24 to 36 hours.  The main result of this newer thinking in the future trajectory of this re-strengthening sub-tropical (but what soon re-gain status as a tropical) system will be the proximity of the worst impacts from Hermine to the greater tri-state area over the next 48 to 72 hours.  

As discussed in the graphic above (courtesy of the National Weather Service off in Upton, New York), the official status of the storm being defined as either tropical as opposed to sub-tropical will not make a tremendous difference overall with respect to the coastal and semi-inland impacts from this low pressure system.  More specifically, aside from breezy to gusty winds episodically moving through the tri-state area, there will be a substantially increased threat for coastal flooding when the larger wave action (and potentially lower-end storm surge influence) becomes synchronized with the high tide cycles that come about between later in the day on Sunday and likely through earlier in the day on Tuesday.  To learn more about other high-impact weather events from across North America, be sure to click here!
