7-3-12. County Warnings
The County Warning weather product provides specific
public awareness and protection weather warnings from
the National Weather Service (NWS). This can include
information on tornadoes, severe thunderstorms, and
flood conditions.
7-3-13. Cyclone
The Cyclone weather product shows the current location
of cyclones (hurricanes), tropical storms, and their
projected track date and time (DD/HH:MM).
7-3-14. Icing (CIP and SLD)
Current Icing Product (CIP) data shows a graphical view of
the current icing environment. Icing severity is displayed
in four categories: light, moderate, severe, and extreme
(not specific to aircraft type). The CIP product is not a
forecast, but a presentation of the current conditions at
the time of the analysis.
Supercooled Large Droplet (SLD) icing conditions are
characterized by the presence of relatively large, super
cooled water droplets indicative of freezing drizzle and
freezing rain aloft. SLD threat areas are depicted as
magenta dots over the CIP colors.
7-3-15. Turbulence
The Turbulence weather product identifies the potential
for erratic movement of high-altitude air mass associated
winds. Turbulence is classified as light, moderate, severe
or extreme (not specific to aircraft type), at altitudes
between 21,000 and 45,000 feet. Turbulence information
is intended to supplement AIRMETs and SIGMETs.
7-3-16. PIREPS and AIREPS
Pilot Weather Reports (PIREPs) are in-flight weather
reports collected from pilots. When significant weather
conditions are reported or forecast, Air Traffic Control
(ATC) facilities are required to solicit PIREPs. A PIREP may
contain adverse weather conditions, such as low in-flight
visibility, icing conditions, wind shear, or turbulence. The
report may also include pilot remarks and type of aircraft
flown. PIREPs are issued as either Routine (UA) or Urgent
(UUA).
