The National Weather Service in State College is developing and testing a new display for Severe Convective Warnings and Local Storm Reports based around the Google Map API.
During a severe weather event NWS polygon warnings will be plotted using the Google Map background. The Google Map background allows the user to zoom in and out, pan, and switch between Terrain and Road backgrounds.
The polygon warnings plotted are color coded: red for Tornado, yellow for Severe Thunderstorm, and green for Flash Flood. A summary of the warnings, in chronological order, is listed to the right of the plot. The summary includes the type of warning, which county the warning is in effect, and the period of time encompassing the warning. Detailed information for the warnings can be displayed by clicking on the summary or by clicking on the red ballon which is centered on the county or group of counties the warning is in effect for. Each severe weather event is displayed and archived for a calendar day. Links to archived events are displayed on the bottom of the page.
In addition, actual Local Storm Reports (LSR) received at the office are plotted on the map. The type of report is indicated by various color-coded icons. Clicking on the icon reveals detailed information from the report including the type of report, where the damage occurred, and when it occurred. The reports are also listed in chronological order in a pane to the right of the map. Users can toggle on/off reports for specific categories by clicking on the checkbox for that category at the bottom of the page.
The page will update every 5 minutes during a severe weather day. During the next day after an event the display will update every hour to accommodate late LSR reports that come in from post storm investigation or storm surveys.
