Subject:  EMWIN FTP Logon Changes Effective June 10, 2013


Effective June 10, 2013, EMWIN FTP users must apply for a

username, a password and provide the IP addresses of systems that

retrieve files from the EMWIN FTP server. This change DOES NOT

affect satellite broadcast or ByteBlaster users.


The IP addresses will be used to obtain access to the server.

Users will need to ensure they use a static IP address, one that

remains the same and is not assigned dynamically and therefore

changes between user sessions.  If users are unsure if they have

a static IP address or need to have one established, they should

contact their Internet provider.


After June 10, users will be required to use their new username

and password to continue to retrieve data from the EMWIN FTP

server. It is strongly recommended that users transition to their

new username and password as soon possible to avoid loss of

service after June 10, 2013.


To apply for a username and password or for other questions,



Rob Wagner


Office of Operational Systems

EMWIN is a low cost satellite weather data broadcast service that

provides one of the most resilient methods of receiving NWS

weather information. The service includes warnings, forecasts,

graphics and imagery. The goal of EMWIN is to provide emergency

managers the capability to respond faster to severe weather,

tsunamis and other hazards.
