The P-ETSS model will be upgraded to: - At 0000 Coordinated Universal Time (UTC) and 1200 UTC, run ETSS v2.3 with the 3-hourly 0.25 degree wind and pressure fields from the new 31 member Global Ensemble Forecast System's (GEFS) and 3-hourly 0.5 degree wind and pressure fields from the 21 member Canadian Ensemble Forecast, instead of the original 3- hourly 0.5 degree 21 member GEFS. - At 0600 UTC and 1800 UTC, run ETSS V2.3 with the 3-hourly 0.25 degree wind and pressure fields from the new 31 member GEFS along with 1 cycle old 3-hourly 0.5 degree wind and pressure fields from the 21 member Canadian Ensemble Forecast, instead of the original 3-hourly 0.5 degree 21 member GEFS. - Increase the number of P-ETSS forecast stations from 333 to 520, while updating the current stations with the latest tidal and datum information. - Operationalize station bias adjustment post-processing and image production. The core ETSS model, which P-ETSS is dependent on, will be upgraded to ETSS v2.3 with the following updates: - Extend the East Coast basin to cover Puerto Rico and the Virgin Islands - Extend the Gulf of Mexico basin to cover the entire Gulf of Mexico - Add an initial water condition Additionally, the ETSS model will be upgraded to: - Increase the resolution of the input Global Forecast System's (GFS) winds from 3-hourly, 0.5 degree (i.e., 55-km) resolution to 1-hourly, 13-km resolution. - Increase the number of ETSS forecast stations from 333 to 520, while updating the current stations with the latest tidal and datum information. - Operationalize image production.
