Current Deep Thunder Forecast for New York Products for Consolidated Edison Operations Storm Classification at 4 km between Data Points Description This page contains an animation that is a visualization of the Deep Thunder forecast focused on Bronx and Westchester Counties.   It uses data from the intermediate nest at 4 km resolution.   Each time step corresponds to twenty minutes of forecast time.   The specific data and representation shown are for potential use for ConEd operations and planning.   In this case, there are maps of a forecasted storm classification scheme as color contour bands, following the legend at the lower right.   The map is accompanied by a number of overlays, including coastlines and state boundaries in black, county boundaries in dark gray and ConEd feeder cell boundaries in light gray, and cities or other locations in black.  Water bodies are shown in gray.   Instructions The animation on this page is composed of a set of individual JPEG images with one hour of forecast time between each frame.   Depending on your connection speed and that of your computer, the animation may take a few minutes to load and decompress in your browser.   When it is completed, the animation will play.   There are VCR-like controls under the animation to enable you to stop playback, play forward or backward, or step through the frames one at a time, control the speed of playback, etc.   If you are having problems viewing or interacting with this animation, make sure your browser has Javascript enabled.
