WEATHER MAPPING AND INTERPRETATION
WEATHER DISPLAY INTERPRETATION
When evaluating various target returns on the weather radar display, the colors denote precipitation intensity
and rates shown in the table.
Weather Mode Color Intensity
Approximate
Precipitation Rate
(in/hr.)
Black < 23 dBZ < .01.
Green 23 dBZ to < 32 dBZ .01 - 0.1.
Yellow 32 dBZ to < 41 dBZ 0.1 - 0.5
Red 41 dBZ to < 50 dBZ 0.5 - 2
Magenta 50 dBZ and greater > 2

Updrafts and downdrafts in thunderstorms carry water through the cloud. The more severe the drafts, the
greater the number and size of the precipitation droplets. With this in mind, the following interpretations
can be made from what is displayed on the weather radar. Avoid these areas by an extra wide margin.

scanning and antenna tilt management may be necessary to identify areas of maximum intensity.
