WeatherBug Total Lightning



The WeatherBug Total Lightning data layer has a number of options in displaying the lightning information. Strikes in the last 1, 15, 30 and 60 minutes can be displayed. Each of these intervals has the option to display Cloud-to-Ground (CG), In-Cloud (IC), or both as well as the Flashes or Strokes.
Strokes are the various discharges that make up a single flash. There are multiple strokes associated with a flash.
At this time, only CG flashes and strokes can have the polarity indicated. This is done by displaying the location of the flash with a positive or negative symbol. The legend displays the type of strike by color with the Cloud-to-Ground showing both positive and negative parameters.
The Animate radio button will allow the user to animate the lightning. The animation can be stopped and cleared by clicking on the selected radio button. The radio button will become unselected and any animation currently displayed on the map will be removed.

The user can operate the animate using the buttons on the legend bar. The animation can be pause, advanced forwards or backwards or jumped to the beginning or end. This area is also the place where selection of the animation duration is done. One and three hour animations can be selected.



The age of the lightning stroke or flash is color coded as indicated in the legend on the animation bar. As the animation is played, the strike colors will change as the lightning animation continues to move forward in time. An example of a three hour animation is shown below.



The user must be zoomed into zoom level 9, 10 or 11 to be able to access map-tip information on the strike. The map tip for lightning displays the location, time and amperage.




Clicking on Details allows the user to see a complete table of lightning data that is being viewed on the current zoom level.


Clicking the Lightning Archive link will open a page that will allow the user to access lighting data up to 6 months in the past. Follow the directions carefully as attempting to download too much data may sometimes not be allowed.
(Important: Viewing of the data is done through Google Maps. The user must have this application downloaded and operational on their desktops to be able to view archive data.)


Flash Flood Guidance - Flash Flood Guidance estimates the average number of inches of rainfall for given durations required to produce flash flooding in the indicated county issued by the National Weather Service (NWS) River Forecast Centers. These estimates are based on current soil moisture conditions. Note, in urban areas, less rainfall is required to produce flash flooding.
Significant River Flood Outlook - This Flood Outlook is intended to provide a general outlook for significant river flooding provided by the NWS Hydrometeorological Prediction Center
Current Fire Perimeters – location of active fire perimeters provided by the Geospatial Multi-Agency Coordination Group (GeoMAC)

Custom Setting Buttons


Views


Each user can save custom views that include the preferred map extent and active data layers. The user can quickly switch between any custom view for rapid visualization of changing weather conditions.

Any view can be set as the ‘default’, which will result in that view getting loaded each time on login. In addition, a view can be selected as ‘Enable 6hr and 12hr animation’.

Views can be ordered by holding down the left mouse button and then dragging and dropping the view name into the desired order.

Upon initial creation of a view with 6 & 12 hour animation enabled, images will begin accumulating for the view at 15 minute intervals. The view must be defined 6 to 12 hours prior to accessing it for playing a complete 6 or 12 hour animation.

When enabling 6 & 12 hour animation for a view, all animate-able layers shall be available for the map extent defined in the view not just the layers that were selected at the time the view was saved.

Select View Button – View names are hot linked so you can quickly switch to a new custom view.



Select Create New View Button – Enter a new name for custom view to save the map extent and active layers.


Slideshow


Custom views can be grouped into a slideshow presentation. The user can configure which custom views to add into a slideshow and which order the views will display as well as how long each view will display.

Select New Slideshow – Select your predefined custom views to add to a new slideshow. The Add View button allows the user to add additional custom views for the slideshow.



Select Slideshow – Slideshows are available for easy selection and will begin playing immediately.



Data View Pane

When a weather data layer is enabled from the Data Menu, the data layer is displayed in the Data View Pane. The Data View Pane provides easy access for the user to view which data layers are displayed on the map and provides additional functions for that data. The Data View Pane can be expanded and collapsed by left clicking on the left edge of the window.




View Data Layer


The first checkbox entry allows the user to turn off a layer from the map, but keeps the data layer entry in the Data View Pane for easy access to turn on when needed.
