Subject: Corrected Date: Forecast Icing Severity Product
To Be Converted From Experimental To Operational:
Effective January 18 2011
Corrected to change date in subject line to 2011.
The following changes have no impact on NOAA Weather Wire
Service Subscribers
This amends a previous TIN 10-51 to note the FIP Potential Icing
Forecast Product has changed to a probability icing forecast
product
Effective Tuesday, January 18 2011 at 1300 Coordinated Universal
Time (UTC), the NWS Aviation Weather Center (AWC) in Kansas
City, MO, will convert the gridded Forecast Icing Severity (FIS)
from experimental to operational status. The FIS provides
forecasts for the potential occurrence of aircraft icing. In
addition the FIP Potential Icing Forecast Product has changed to
a Probability Icing Forecast Product. See the link below for
details on GRIB file changes.
http://aviationweather.gov/notice/fip_severity.php
The FIS domain covers the contiguous 48 United States and
adjacent coastal waters in 1000 foot increments between 1000 and
30,000 feet above Mean Sea Level. The FIS is a forecast
extension of the current icing severity (CIP) product and
predicts the icing severity out to 12 hours. Forecast hours
include H+01, H+02, H+03, H+06, H+09, and H+12. The FIP is
produced automatically from the 20 km Rapid Update Cycle (RUC)
model runs.
The WMO Headings for the FIP Icing Severity are as follows.
