U.S. Weather Research Program, Hurricane Landfall Workshop Report

This report contains the results of workshop participants who prioritized research and observational opportunities to achieve pre-landfall track forecast gains of this track-related research to provide NHC forecasters improved track guidance that will: (i) increase the preparation lead time by at least 12 h; (ii) extend the length of forecasts to 96 h with the same accuracy as the present 72-h guidance, and (iii) use new techniques that provide measures of confidence that will reduce the present 4:1 overwarning of coastal areas to a ratio of 2:1 in 90% of hurricane landfalls that are essentially perpendicular to the coastline.
