The US Northeast Coastal Ocean Forecast System (NECOFS): Applications for simulations of Hurricane- and Extratropic Storm-Induced Surges and Inundations Coastal “Hot Spots” During NorʻEasters Rockland: FS ~ 12.5+ ft/ waves not an issue Bath/Woolwich: FS ~ 12.5+ ft + heavy rains Portland: FS = 12 ft/commercial street floods at 13.5 ft Saco: Splash-over mainly with 10-15+ ft waves + moderate to high storm tides Wells/York: Splash-over mainly with 15-20 ft waves + moderate/high storm tides Hampton: [Hampton Bay floods at only 11.25 feet (Fort Point Gage)] Splash-over mainly with ~ 15 - 20 ft waves + moderate/high storm tide Scituate, MA Hampton Saco Northeast Coastal Ocean Forecast System (NECOFS) -‐ produces 3-‐day forecast of surface weather, waves, elevaQon, 3D currents, temperature, salinity Opera8on Components 1. Meso-‐scale meteorological forecast model (WRF), with horizontal resoluQon of 9 km. 2. Hydrodynamics-‐temperature, salinity, 3-‐D currents, sea level. GOM2: Cut oﬀ 300-‐m oﬀ the shelf break region; GOM3: Cut oﬀ 1500-‐m oﬀ the shelf break. The upstream boundary condiQons are speciﬁed by the wind-‐ induced ﬂux. Horizontal resoluQon varies from 25 km to 500 m. 3. Surface waves-‐ A nested WWIII-‐SWAVE system; 4. Mass Coastal FVCOM: High-‐resoluQon coastal model nested with GOM3, with horizontal resoluQon up to 15 m. 5. Scituate InundaQon FVCOM: A fully current-‐wave coupled model system, with horizontal resoluQons up to 10 m. 4/3/12 Domain 2 Domain 1 Domain 3 Domain 2 Regional Domain: 9 km Domain 3 Hindcast Local domain: 3 km Large domain: 27 km GOM3 Mass Coastal FVCOM (Finest resolution: 15 m) Element: 173224 Node: 103699 273 -2.0 WWIII-FVCOM-SWAVE Nesting 4/3/12 Web Map Server to display the hindcast data 4/3/12 4/3/12
