SILVER SPRING, MARYLAND 20910-3283
Operations Manual Letter 4-99

In order to reflect the changes that each office's operations will undergo as its Advanced Weather Interactive Processing System (AWIPS) is commissioned, this OML outlines the following changes in terminology that shall be applied:

The facilities identified as NEXRAD Weather Service Forecast Office (NWSFO) and NEXRAD Weather Service Office (NWSO) will be renamed to reflect their status as Weather Forecast Offices (WFO) once the AWIPS is commissioned. The policy and procedures detailed in the reference chapters apply to offices with commissioned AWIPS.
The term AWIPS may be applied to all instances where the term Automation of Field Operations and Services (AFOS) is used in the chapter with no impact on the policy or procedure(s) being defined.

Assistant Administrator

for Weather Services
