Hi Julie,

Have you received word from Mike Carelli or others at NWS regarding delays
in the dissemination of the NIDS data to be made available on 1 Jan 2001?
To my knowledge, there has not been an official statement and yet we have
heard there is a possibility of delays due to de-encryption methods at
some NEXRAD radar sites.

Will you be sending out advance information pertaining to the
distribution, e.g., which sites are included or excluded and the number of
products being made available?

stream.
Happy New Year!
Linda
