Subject: Changes to RWRTX Products in Texas Effective
 July 26, 2017

Effective Wednesday, July 26, 2017, at 1800 Coordinated
Universal Time (UTC), 200 PM EDT, the NWS Texas Weather Forecast
Offices (WFO) in Lubbock (LUB), Austin/San Antonio
(EWX) and Dallas/Fort Worth (FWD) will issue their current
Regional Weather Roundup (RWRTX) product under new AWIPS IDs.
The NWS created new AWIPS IDs specific for each office for ease
in parsing and locating the product easier on websites.

NWS partners and users will need to make necessary changes to
their communications systems to receive the new AWIPS IDs listed
in Table 1 by July 26, 2017.

The waiver is requested to implement this change before the
forecaster refractor date of August 14, 2017 when it will become
more difficult for users and NWS staff to locate the correct
office product under the RWRTX. Additionally, since only three
field offices are impacted by this proposed change and the
change itself is minimal, a 30 day (in contrast to a 75 day)
notice is sufficient time for partners and users to make
necessary changes to their communication systems to receive the
new AWIPS IDs provided the Service Change Notice.
The effective date of this change is sooner than specified by
NWS Policy (NWS Instruction 10-1805).  The shorter advance lead
time was approved because only three field offices are impacted
by this proposed change and the change itself is minimal.
Starting on July 26, 2017, users can find the products via the
new AWIPS IDs at:

On or about August, 14, 2017 the link will change to the
