Radar Facts
To find a safe and comfortable route through the precipitation area,
study the radar image of the squall line while closing in on the
thunderstorm area. In the example shown in figure 5–30, radar
observation shows that the rainfall is steadily diminishing on the left
while it is very heavy in two mature cells (and increasing rapidly in a third
cell) to the right. The safest and most comfortable course lies to the left
where the storm is decaying into a light rain. The growing cell on the
right should be given a wide berth.
