New Implementation (ETSS 2.2/P-ETSS 1.0)


The Extra-Tropical Storm Surge (ETSS) model is a modification of the Sea Lake and Overland Surges from Hurricanes (SLOSH) model to use 0.5 degree Global Forecast System (GFS) wind and pressure input to predict storm tide (surge + tide) from extra-tropical storms.  Four times a day, it creates storm tide guidance including overland calculation for extratropical storms in the continental U.S. and Alaska.


The Probabilistic Extra-Tropical Storm Surge (P-ETSS) model is a modification of the ETSS model to use 21 ensemble members from the Global Ensemble Forecast System (GEFS) to generate probabilistic storm surge products from extra-tropical storms.


Summary:

ETSS 2.2 (July 12, 2017) does the following:
