SUBJECT:  WIND PROFILER DATA PRODUCTS TEMPORARILY
          DISCONTINUED

EFFECTIVE OCTOBER 1 2008 ALL NWS WIND PROFILER PRODUCTS WILL 
BE UNAVAILABLE FOR APPROXIMATELY 3 TO 5 WEEKS.

THE SUSPENSION IN AVAILABILITY OF WIND PROFILER DATA IS 
NECESSARY BECAUSE OF RECENTLY INDENTIFIED IT SECURITY 
THREATS.  THE WIND PROFILER NETWORK CURRENTLY OPERATES ON 
OBSOLETE EQUIPMENT THAT CAN NOT SUPPORT NECESSARY IT 
SECURITY METHODS. INTERCONNECTION TO MAJOR NWS SYSTEMS 
EXTENDS THE VULNERABILITY TO OTHER NWS IT SYSTEMS.

NWS IS WORKING ON AN ALTERNATE PLAN WITHIN NOAA /WITH THE 
METEOROLOGICAL ASSIMILATION DATA INGEST SYSTEM GROUP IN NOAA 
RESEARCH/ THAT WILL ALLOW HOURLY WIND PROFILER DATA TO BE 
AVAILABLE FROM EACH SITE. NWS IS CONTINUING TO WORK TO MAKE 
SIX MINUTE DATA AVAILABLE AND WILL UPDATE PROGRESS AT A 
LATER DATE.
