SUBJECT: Amended, Comment Period extended through April 30,
 2017, on Lake Effect Snow (LES) Warning Polygons from
 Weather Forecast Office (WFO) Buffalo, NY

Amended to add new zones around Lake Erie and to extend comment
period through April 30, 2017

WFO Buffalo, NY, will produce experimental LES polygon warnings
around Lake Erie this winter and continue the polygons around
Lake Ontario per last year`s experiment. The experiment adds
latitude/longitude coordinates to segments of the Winter Weather
Message text product (BUFWSWBUF) and provides increased
specificity with polygons issued for sub-county areas.

These coordinates will be added to products containing the LES
Warning Valid Time Event code (LE.W) for certain zones in
western and north central New York along Lake Erie and Lake
Ontario. WFO Buffalo will begin issuing the experimental product
with the coordinates on or about Tuesday, December 6, 2016.

When a LES Warning is in effect for these areas, WFO Buffalo
will also produce a graphic displaying these polygons at:

Geographic Information Systems (GIS) users will be able to use
these coordinates to plot areas most prone to heavy LES.  NWS
Buffalo will also provide a downloadable file of the geographic
data on its website at:

The purpose of these polygons is to display small areas of
intense snowfall with low visibility at sub-zone levels in
upstate New York where the highest impacts to transportation and
commerce are expected.

Coordinates and polygons are only for experimental use. NWS
Buffalo will continue to issue operational zone-based LES
warnings for these areas.

The following WFO Buffalo Public Zones will be included in this

Zone Number    Zone Name
NYZ001    Niagara
NYZ002    Orleans
NYZ003    Monroe
NYZ004    Wayne
NYZ005    Northern Cayuga
NYZ006    Oswego
NYZ007    Jefferson
NYZ008    Lewis
NYZ010    Northern Erie
NYZ011    Genesee
NYZ012    Wyoming
NYZ013    Livingston
NYZ014    Ontario
NYZ019    Chautauqua
NYZ020    Cattaraugus
NYZ021    Allegany
NYZ085    Southern Erie

The feedback gathered from this experiment will help us provide
more precise watches and warnings in the future and will support
a decision on whether to make these warning polygons
