GMS-5 images were obtained in near real time via anonymous ftp from the Department of Information and Computer Sciences at the University of Hawaii. Surface synoptic reports were acquired in near real time via the Meteorology Department gopher server at The Florida State University. Brian Getzewich assisted with the data processing. We thank two anonymous reviewers for suggestions that led to significant improvements in the manuscript. This study was supported in part by NASA Grant NAGW-3944.
