Storm Cells 
Storm activity is displayed on the 
moving map with cells measuring 
from 2km to 12km in size.  The detail 
levels vary depending on many 
factors, including size of requested 
area, amount of weather, and 
distance from center of picture.  
Although a higher level of detail can 
be displayed, due to the 5 to 10 
minute age of the weather and storm 
movement it does not provide 
additional useful navigational 
information.  Cells are displayed with 
three levels of intensity. 
The three levels of intensity are:

You should always assume that weather intensity 
levels have increased since the image was received. You should 
not fly close to any activity, including the green cells!

NexRAD Picture Boundaries 
Two concentric dashed circles  
denote the boundaries of the 
current weather picture on the 
moving map.  The inner green 
circle indicates the area where 
weather is represented in the 
most detail. The outer yellow 
circle indicates where the 
weather is represented in less 
detail.  Any weather 
completely outside of the 
outer yellow circle will not be displayed. Cells display when 
any part contacts the outer yellow circle, so large cells can extend 
beyond the circle.
