Lightning Detector Map and Data |
|
|
|
The data presented in the Lightning Map, Detector Summary and Storm Cell
Analysis is color keyed to indicate the relative strength of the storms.
This color scale is shown in the Storm Strength Key below the Lightning Map with
the associated storm classes below ranging from thundershowers to strong
thunderstorms.
On the map, storms are represented by a box indicating the relative distance of
the strokes associated with the storm. The border color of the box of the
fill color of the box represent the intensity of the storm. If the box is
a solid color, that indicates a high content of positive cloud to ground strokes
which generally indicates that the storm is or has the potential to become
severe. Below is an example of some strong and severe thunderstorms, two
of which have a high content of positive cloud to ground strokes. |

When a storm is represented by a circular or oval shape, the indication is of
more tightly grouped strokes and that lightning is extremely likely in the
immediate area. Below is an example of such a storm depiction. In
addition, if there are storms within the yellow range ring (30 miles of
Bentwater), the border of the
map will be yellow ("yellow alert"). If there are storms within the red
range ring (10 miles of Bentwater), the border of the map will be red ("red alert"). |

The Storm Cell Analysis will show information for each of the storm boxes
presented on the Lightning Map. There may be storms indicated in the Storm
Cell Analysis that do not have a corresponding box on the Lightning Map if the
storms are distant enough to be beyond the limits of the map. The Analysis
contains some specific information regarding the relative strength of the
strokes in the storm. |

REMEMBER! Do not make safety decisions based solely on the information
shown on the Lightning Detection page. These images and analysis are for
informational purposes only. Seek further information from the National
Weather Service and/or radio and television before you expose yourself to
potential thunderstorm activity! |
