subject: new fire and public forecast zones and boundary changes
for central and northeast Virginia, effective April 7, 2015

effective Tuesday, April 7, 2015, at 900 am eastern daylight
time (edt), 1300 coordinated Universal time (utc), several changes
will be made to existing fire and public forecast zones in
Central, Northeast and southeast Virginia.

These changes include splitting 7 existing fire and public
forecast zones in central and northeast Virginia into 14 zones.
In addition, 2 fire and public zones in southeast Virginia will
be split into 3 zones. The new zones are shown below in table 1.

In all cases, fire and public zones are identical in zone name,
zone number and geographic extent.

A graphic depicting these changes is online at:

http://www.NWS.NOAA.Gov/os/public/akq_zones.Pdf

these zones are being changed to improve warning accuracy in
highly populated areas in central and northeast Virginia. These
zones have climatological differences affecting precipitation
type during winter weather events. The changes will result in
more geographically precise forecasts, watch and warning
products and will enhance web-based graphical product
consistency and appearance.

The zone change in southeast Virginia will also result in more
geographically precise watch, warning and advisory products, and
improve warning accuracy during tropical cyclone and winter
storm events.

These zone changes require partners and users to take
appropriate action to receive the new zone products using the
Universal generic code (ugc) zone code format (z) listed in
table 1.

Products affected by this change are listed in table 2. This
list of products may not be exhaustive and other products which
contain ugc (z) may also be affected.
