Back to Icing Page or
The Current Icing
Product (CIP) and Forecast Icing Potential (FIP) are
computer-generated three-dimensional analyses of information related
to the likelihood of encountering icing conditions. This information
is available for the 48 contiguous United States, much of Canada and
Mexico, and their respective coastal waters.
The CIP/FIP graphics suite is automatically produced with no human
modifications. Information on the graphics is determined from
observational data including WSR-88D radar, satellite, pilot weather
reports, surface weather reports, lightning and Numerical Weather
Prediction model output.
CIP/FIP graphics may be used as a higher-resolution supplement to
AIRMETs and SIGMETs, but not as a substitute for the
icing severity and other information they provide. CIP/FIP are
authorized for use as an unrestricted, supplementary weather product.
Page 4 for a definition of these terms.
The Icing Page contains 4 major sections:
- The first section contains a thumbnail of the current icing AIRMETs in
dashed blue lines and SIGMETs
(if any) in solid red lines. Clicking on the thumbnail image will
produce a larger view.
- The latest voice PIlot REPorts (PIREPs) of
icing are available in the second section and can be obtained by
clicking on the desired map region. These images are updated about
every 15 minutes and depict location and severity of aircraft icing
as reported by pilots.
- The third section contains a link to CIP/FIP icing products. The
Icing Product (CIP) represents the latest analysis
of potential icing regions. Besides the most-recent analyses, a
forecast of anticipated icing conditions is available in the Forecast
Icing Potential (FIP) product.
- The last section contains links to graphics depicting the height
of the lowest freezing level. The colors represent the height in
hundreds of feet above mean sea level (MSL) of the lowest freezing
level. Regions in white indicate that the surface and the entire
depth of the atmosphere are below freezing. Hatched regions (if
present) represent areas with multiple freezing levels and a more
description is available.
