THE LABOR DAY 1998 DERECHO

This slide show was adapted from presentations made for the Central New York Chapter of the Aerican Meteorological Society, and the 24th Lyndon St. College AMS/NWA Northeastern Storm Conference. It is designed to be run using a screen resolution of 1024 x 768 or higher. Lower resolutions will work, but will increase the scrolling needed to view the presentation. You can increase the size of the veiwing window (to help reduce the scrolling) by deactivating or minimizing the button bars on your browser (F11 for Internet Explorer). Comments and suggestions are greatly appreciated.
