Subject:  Corrected: Changes to the county name and the Federal
          Information Processing Series (FIPS) code for
          Shannon County, SD, Effective for NWS
          Products and Services on October 1, 2015

Corrected to add an effective time of 1600 Coordinated
Universal Time (UTC), 10:00 AM Mountain Daylight Time (MDT),
October 1, 2015.

The name of Shannon County, SD, changed to Oglala Lakota County,
SD, effective May 1, 2015. Because of the extensive coordination
and planning required by the weather enterprise and the
emergency management community to successfully complete this
change, the official date of change for NWS products and
services for the county name change and the FIPS code change
will be October 1, 2015, at 1600 UTC, 10:00 AM MDT.

Major points to be aware of for NWS products and services:

The county name will change from Shannon to Oglala Lakota.  The
existing county boundaries will not change.

-The FIPS code changes from 46113 to a 46102. FIPS codes are
assigned and maintained by the U.S. Census Bureau.

-The Universal Geographic Code by County (UGC-C) will change
from SDC113 to SDC102.

-The NWS public forecast zone name will change from Shannon to
Oglala Lakota. The existing UGC by Zone (UGC-Z), SDZ042, remains

-No NWS fire weather zone names or numbers will change.

The UGC-C, used in some NWS products and the county portion of
the NOAA Weather Radio All Hazards (NWR) Specific Area Message
Encoding (SAME) code, is derived from the FIPS code. Therefore,
on October 1, 2015, the NWS will discontinue using the current
FIPS code for Shannon County (46113) and begin using the new
FIPS code (46102) for Oglala Lakota County.  The correct county
code is critical for receiving tornado, severe thunderstorm, and
flash flood watch, warning, and follow-up products.

convenience, keep the current code (46113) in their systems
until October 1, 2015, and delete the old code (46113) after the

All NWS partners and users who receive NWS products and parse

Lakota County in their software and systems operations.

In the event October 1, 2015, is declared a Critical Weather Day
(CWD) or significant weather is occurring, or forecast to occur,
in or near Oglala Lakota County, SD, implementation of this NWS
change will occur at 1600 UTC on the next weekday not declared a
CWD Day and when no significant weather is occurring in or near
