Abstract: The Coastal Coupling CoP Total Water Level (TWL) Working Group, led by Dr. Margaret Palmsten (USGS) and Dr. Hassan Mashriqui (NOAA/NWS), is hosting a TWL Town Hall focused on the challenges and areas of opportunity of operational TWL modeling. Three lightning talks (from a private, federal and academic perspective) will start off the town hall, followed by a short panel discussion and then the audience will be encouraged to participate in a 30-minute question and answer period.
