During the remainder of the day on 31 August, there was some evidence of an eye structure on polar-orbiting satellite (POES) microwave imagery, even though no eye was obvious on conventional geostationary satellite (GOES) visible or IR imagery (below,<\/em><\/strong> courtesy of the CIMSS Tropical Cyclones<\/a><\/strong> site)<\/em>.<\/p>\n
