a Date/time is for sustained wind when both sustained and gust are listed. b Except as noted, sustained wind averaging periods for C-MAN and land-based ASOS reports are 2 min; buoy averaging periods are 8 min. c Storm surge is water height above normal astronomical tide level. d Storm tide is water height above National Geodetic Vertical Datum (1929 mean sea level). f 10-minute average. g 6-minute average. h 15-minute average. i South Florida Water Management District (SFWMD) site. j Carolinas Coastal Ocean Observing and Prediction System (Caro-COOPS) site. k University of South Florida site. l North Carolina Environment and Climate Observing Network (ECONET) site. Table 4. Preliminary track forecast evaluation (heterogeneous sample) for Hurricane Ernesto, 24 August – 1 September 2006. Forecast errors (n mi) are followed by the number of forecasts in parentheses. Errors smaller than the NHC official forecast are shown in bold-face type. Verification includes the depression stage but does not include the extratropical stage.
Table 5. Preliminary intensity forecast evaluation (heterogeneous sample) for Hurricane Ernesto, 24 August – 1 September 2006. Forecast errors (kt) are followed by the number of forecasts in parentheses. Errors smaller than the NHC official forecast are shown in bold-face type. Verification includes the depression stage but does not include the extratropical stage.
Table 6. Watch and warning summary for Hurricane Ernesto, 24 August – 1 September 2006.
Figure 1. Best track positions for Hurricane Ernesto, 24 August – 1 September 2006. Track during the extratropical stage is based in part on analyses from the NOAA Ocean Prediction Center and the NOAA Hydrometeorological Prediction Center. 
Figure 2. Selected wind observations and best track maximum sustained surface wind speed curve for Hurricane Ernesto, 24 August – 1 September 2006. Aircraft observations have been adjusted for elevation using 90%, 80%, and 80% reduction factors for observations from 700 mb, 850 mb, and 1500 ft, respectively. Dropwindsonde observations include actual 10 m winds (sfc), as well as surface estimates derived from the mean wind over the lowest 150 m of the wind sounding (LLM), and from the sounding boundary layer mean (MBL). Estimates during the extratropical stage are based on analyses from the NOAA Ocean Prediction Center and the NOAA Hydrometeorological Prediction Center.
