Caption: +(upper left) DT pressure (shaded in hPa), DT-850-hPa vertical wind shear (standard barbs in kt; red < 20 kt; black >= 20 kt), and 925-850-hPa layer-average relative vorticity (solid green contours every 2.0x10-5 s-1 starting at 2.0x10-5 s-1). +(upper right) Total column PW (shaded in mm), 1000-700-hPa thickness (solid contours every 3 dam), and 1000-700-hPa layer-average wind (standard barbs in kt). +(lower left) 900-700-hPa layer-average relative humidity (shaded in %), 850 hPa streamfunction (solid black contours every 3.0x106 m2 s-1), and 850 hPa vertical motion (solid magenta contours every 2.0x10-3 hPa s-1 starting at -2.0x10-3 hPa s-1; negative values only). The vertical motion field was smoothed using a Gaussian filter with a weight of 9. +(lower right) 700-500-hPa layer-average relative humidity (shaded in %), 600 hPa streamfunction (solid black contours every 6.0x106 m2 s-1), and 600 hPa wind (standard barbs in kt). +Image was generated from 0.5x0.5o NCEP CFS Reanalysis data; TC position and NHC best track statistics are plotted when available.
