Figure 12-50 Cell Irregularities
Thunderstorm development is rapid. A course may become blocked within
a short time. When displaying shorter ranges, periodically select a longer range
to see if problems are developing further out. That can help prevent getting
trapped in a “blind alley” or an area that is closed at one end by convective
weather.

In areas of multiple heavy cells, use the Vertical Scan feature along with
antenna tilt management to examine the areas. Remember to avoid shadowed
areas behind targets.
