Legend
(1) Solid line indicates terminal areas with
ceilings less than 1,000 ft and/or visibility
less than 3 miles (IMC) - colored red
(2) Scalloped line indicates terminal areas
with ceiling between 1,000 ft but less than
3,000 ft and/or visibility greater than
3 miles but less than 5 miles (MVFR) -
colored blue
(3) Bold long-dashed lines indicate areas of
moderate or greater turbulence
NOTE: The chart does not depict light
turbulence. Moderate turbulence is
symbolized by an inverted V, severe
turbulence uses the same inverted V
with a second inverted V above.
(a) The numbers to the left of a slash (/)
indicate tops of forcasted turbulance,
and numbers to the right indicate the
base of the forcasted turbulance in
hundreds of feet MSL
(b) No figure to the right of the slash
indicates turbulance from surface
upward, while absence of a figure to
the left of the slash indicates
turbulance above the limits of the chart
(24,000 feet MSL)
(4) The surface 32-degree isotherm is depicted
with a dotted line and is labeled
