A notable increase in the areal coverage of deep convection was seen around the center of Julia as it approached the coast, suggesting a trend of further intensification just prior to landfall.<\/p>\n Julia was upgraded from a Tropical Storm to a Hurricane at 2300 UTC<\/strong><\/a> on 08 October — an analysis of deep-layer wind shear<\/strong><\/a> at that time from the CIMSS Tropical Cyclones<\/strong><\/a> site (below)<\/strong><\/em> indicated that Julia was moving through an environment of very low shear (which favored further intensification). The tropical cyclone was also traversing warm water with Sea Surface Temperature<\/strong><\/a> values around 29\u00baC.<\/p>\n GOES-16 Infrared Window (11.2 \u00b5m) images, with contours of deep-layer wind shear valid at 2300 UTC [click to enlarge]<\/p><\/div>A DMSP-17 SSMIS Microwave (85 GHz) image at 2353 UTC (below)<\/strong><\/em> showed that a closed eyewall was beginning to develop, but still remained open to the west-southwest.<\/p>\n<\/a>
