| Enhanced Product National Implementation of the use of 1 inch Diameter Hail Criteria |
The Severe Thunderstorm Warning (SVR) is an
alphanumeric product providing short-fused
warning in¬formation on hazardous conditions
associated with thunderstorms which are expected
to pose a threat to life and/or real property.
This product is prepared by each National Weather
Service (NWS) Weather Forecast Office (WFO)
for their County Warning Area (CWA) of
responsibility. In the Western Region (WR) and
Central Region (CR) a Severe Thunderstorm Warning
is currently being issued experimentally based on
expectation of winds gusting to 58 mph or greater
and/or hail of one (1) inch diameter or greater.
Pending successful completion of this experiment,
all NWS sites will issue Severe Thunderstorm
Warnings based on these criteria.

| Enhanced Product- Use of 1 inch Diameter Hail as a Criterion for Severe Thunderstorm Warnings in NWS Central Region |
The Central Region Severe Thunderstorm Warning (CR
SVR) is an alphanumeric product providing
short-fused warning in¬formation on hazardous
conditions associated with thunderstorms which
are expected to pose a threat to life and/or real
property. This product is prepared by each
National Weather Service (NWS) Weather Forecast
Office (WFO) for their County Warning Area (CWA)
of responsibility. Traditionally the SVR has
been based on expectation of winds gusting to 58
mph or greater and/or hail of ¾ inch diameter or
greater. In the Central Region, the minimum hail
criterion is increased to one (1) inch in
diameter. This change is motivated by research
indicating significant damage does not occur
until hail size reaches 1 inch in diameter, and
in response to requests by core partners in
emergency management and the media |

| Experimental LSR Webpage Product Using Google Map Technology |
The purpose of this experimental web page is to
provide our customers and partners a simple way
to display NWS polygon warnings and LSR reports
on an interactive map that customers can use to
zoom in to their specific location. Right now,
most NWS warnings and LSR’s are in text form.
Those that are plotted are done so on a static
background map. By incorporating Google Map
technology the user can easily switch from a
terrain map to a road map background and quickly
zoom and pan around for their location. |

| Experimental Alaska Region NDFD Grids |
PDD updated to include new elements:
Hazards, Weather, Temperature, Dew Point, Wind
Gust, Sky Cover, Apparent TEmperature, RElative
Humidity, Quantitative Precipitation Forecast
(QPF) and Snow Amount.
Under statute, the National Oceanic and
AtmosphericAdministration (NOAA) National Weather
Service (NWS) is charged to collect data on
climate, water, and weather, provide forecasts
and warnings of severe weather in order to
protect life and property, and create and
disseminate forecasts and other weather
information for the benefit of a wide range of
weather sensitive businesses and activities. By
capitalizing on rapid advances in science and
technology and infusing these advances into its
operations, the NWS has taken steps to
proactively respond to ever changing and growing
demands of its users. The most
recent experimental digital datasets (and
associated graphic forecast displays) integrated
into NDFD are the following elements for Alaska:
Maximum Temperature, Minimum Temperature, 12-hour
Probability of Precipitation, Wind Speed, Wind
Direction, and Significant Wave Height. |

| Experimental Bulleted Winter Storm (WSW) and Non-Precipitation (NPW) Products National Optional |
Last year, WFO Reno issued bullet formatted WSW
and NPW products with a format similar to severe
thunderstorm and flash flood warnings. This
format is easier for users to read and quickly
gather vital watch, warning and advisory
information. During the 2009/2010 winter season,
the use of the bullet formatted WSW/NPW will be
expanded to all of Western and Central Region
offices plus selected offices in other regions |

| Experimental Carolinas Coast/Southeastern Marine Web Portal |
The National Weather Service's (NWS)Experimental
Carolinas Coast/Southeastern Marine Web Portal
provides marine observations, forecasts and short
and long-fuse warnings for the coastal waters of
North Carolina, South Carolina and northern
Georgia and the Atlantic and Gulf coast areas of
the Southern Region. The recent development of
regional and sub regional coastal ocean observing
systems under the national Integrated Ocean
Observing System (IOOS) initiativecreates new
opportunities for increased meteorological and
oceanographicdata availability. |

| Experimental Google Map Display Service of NWS Weather Data |
Utilization of Google Maps across National Weather
Service (NWS) web pages has proven very popular
for both users and NWS webmasters and Information
Technology Officers (ITO). An increasing number
of NWS webmasters and ITOs are creating diverse
Google Map service applications to display
various existing NWS data sets in a more
convenient manner for web users. It is
impossible to issue individual PDDs for the large
number of experimental Google Map applications
being developed across Western Region (WR). This
umbrella PDD, as defined in NWSI 10-102, allows WR
webmaster and ITO creativity in producing
experimental Google Map applications, while
managing implementation and project tracking and
information sharing. Requirements defined in PDD. |

| Experimental Graphical Area Forecast |
The Geographical Area FOrecast (GFA) product is a
graphhical representation of the current
operational production of aviation area
forecasts, which provide an overview of weather
conditions which could impact aviation
operations. The experimental graphical Airman?s
Meteorological Advisory (G-AIRMET) is a
BUFR-formatted time-series depiction of aviation
hazards occurring with occasional or greater
frequency throughout the conterminous U.S. and
adjacent coastal waters (NWS, 2005a). The
aviation hazards depicted in the experimental
G-AIRMET (FAA, 2006) are:
(1) Areas of surface visibility below three (3)
statute miles, including the weather causing the
visibility restriction.
(2) Areas of cloud ceilings with bases less than
1000 feet above ground level (AGL).
(3) Areas of widespread mountain obscuration
where Visual Meteorological Conditions (VMC)
cannot be maintained, including the weather
causing the obscuration.

| Experimental Grid-based Emergency Communications Center Dispatch Area (ECCDA) Forecast Summaries, or ECCDA Radio |
WFO Medford has developed a stand-alone ECCDA
formatter based on fire weather grids and
available on the Western Region server at 2.5 sq.
km resolution. This formatter produces the ECCDA
product automatically once all needed grids are
available and the ECCDA discussion is produced
(as is done currently). No additional forecaster
intervention required. ECCDA text resulting from
the grid-based formatter is written in a shorter,
conversational style. This style will be easier
for fire dispatchers to read on agency radio and
easier for listeners to understand and retain.
The new formatter will be tested at four WFOs
serving northern California fire weather user
(Medford, Eureka, Sacramento and Reno), from
approximately January 1 to October 1 2009.
Existing ECCDA products will continue to be
available and all other aspects of the ECCDA
program, including web availability, remain the
same. |

| Experimental Gridded Significant Wave Heights from the National Centers |
The traditional format for the significant wave
height products from the National Centers are
graphical depictions of the observed and forecast
wind-driven waves for the Atlantic and Pacific
Oceans adjacent to the coasts of the Continental
United States (US) and extending south over the
Caribbean Sea and the west coast of Central
America. These graphical products have been
prepared for many years in the raster format by
the Ocean Prediction Center (OPC) and the
Tropical Prediction Center’s (TPC) Tropical
Analysis and Forecast Branch (TAFB) and
transmitted via radiofax and the internet. The
production and dissemination of the traditional
raster format for the graphical significant wave
height products from the OPC and TAFB will
continue.
The experimental gridded products will be
prepared for the initial wave heights, the 24
hour and 48 hour forecast wave heights in a
gridded format. The experimental gridded
products will be disseminated by the National
Weather Service (NWS) Telecommunications Gateway
to the Weather Forecast Offices (WFOs), National
Centers, and other users.
