  Deep Thunder Forecast for New York

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 thirty 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.  





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.

If the forecast information presented on this page does not seem to be current and you have visited this site recently, the results of the previous visit may have been saved in your web browser's cache. If so, you should change your cache settings (e.g., File->Preferences->Advanced->Cache in Netscape and set the document comparison to "Every time"). When you restart your browser, the problem should be solved. For your current session, you should manually clear the cache and reload the page.  


The storm classification is based upon historical criteria that ConEd has defined for this portion of their service area as outlined in the table below.   Currently, this visualization of the forecasted storm classification is using storm intensity (winds and liquid precipitation) as criteria.  Predictions of storm duration, gusts and snow will be considered in later versions.
