Radar Facts
AVOID VNOTCH BY 20 MILES
A large isolated echo sometimes has the configuration that is shown
in figure 541. This echo is called Vnotch or flying eagle although
some imagination may be needed by the reader to see the eagle.
V–notch echoes are formed by the wind pattern at the leading edge (left
front) of the echo. Thunderstorm echoes with Vnotches are often
severe, containing strong gusty winds, hail, or funnel clouds, but not all
V–notches indicate severe weather. Again, severe weather is most
likely at S in figure 5–41.
