The Alaska Low Level Significant Weather Graphic
(SWL) is a graphic product providing an outlook
forecast of significant weather for aviation
below 25,000 ft (FL250). |

| Alaska Graphic Area Forecast |
The Alaska Graphic Area Forecast (GFA) is a
graphical representation of forecasts contained
in the text Area Forecasts (FA) for Alaska. The
GFA is comprised of four separate graphics
produced using NMAP software at the Alaska
Aviation Weather Unit (AAWU). |

| Graphical Severe Weather Warnings |
The Graphical Severe Weather Warning (GSWW)
combines the polygon generated
by WARNGEN for a TOR or SVR issuance with a
current radar reflectivity image, high-detail GIS
map backgrounds showing roads, cities, and
terrain, and a summary of demographic information
for the population at risk. The GSWW also contains
the text of the warning and any subsequent SVSs
issued for that warning.... |

| Marine Forecast Matrix |
The National Weather Service (NWS) Marine Forecast
Matrix (MFM) provides a tabular forecast of wind
direction and speed, swell direction and height,
wind wave height, significant wave height, cloud
cover, probability of precipitation, and areal
precipitation coverage. |

| NDFD Quantitative Precipitation Forecast (QPF) for Hawaii |
On November 1, 2006, the National Oceanic and
Atmospheric Administration (NOAA) National
Weather Service (NWS) will introduce Quantitative
Precipitation Forecast (QPF) for Hawaii to the
National Digital Forecast Database (NDFD) as an
experimental element. QPF is already available in
NDFD on an experimental basis for the conterminous
U.S. (CONUS), the 16 pre-defined NDFD CONUS
subsectors, Puerto Rico, and the U.S. Virgin
Islands. |

| ABRFC Recreational Forecast Graphics |
The National Weather Service (NWS) is the agency
responsible for issuing river forecasts and flood
warnings for the United States. This information
is provided in order to protect life and property
as well as to enhance the national economy. In
cooperation with national, state and local
agencies, as well as private organizations and
the public, the NWS determines the river levels
which correspond to the beginning of significant
damage from high water. This level of water at a
given river location is termed flood stage. The
NWS issues special river forecasts and flood
warnings when levels are expected to equal or
exceed flood stage. In addition to problems
caused by flooding, various users have danger and
incur risk due to river fluctuations and river
levels lower than flood stage. Examples of these
types of users of river forecast information
include navigation interests or the general
public who use the river and river banks for
recreational purposes. The experimental
Recreational Forecast graphics are Internet web
pages that depict the expected river levels for
the Illinois River of Oklahoma, a very popular
canoe and raft float stream. These expected
stream flow levels are translated to a river
floatability index based on guidelines provided
by the Illinois River Association and the State
of Oklahoma Scenic Rivers Commission.
Recreational interests can use the information to
better insure a safe experience on and near the
river. |

| Red Flag Potential Index |
The Red Flag Potential Index (RFPI) is a graphical
product produced by forecasters at WFO Las Vegas
(VEF) using GFE/IFPS. Ratings of Red Flag
potential (numbers 1 through 4) for the next
three days (today, tomorrow and the next day) are
calculated using forecasts of relative humidity
and prevailing 20-ft, 10-minute average surface
wind, along with forecaster knowledge of other
factors such as critical fire conditions and the
existence of active wildfires. The RFPI is
intended to be used as general guidance,
primarily for planning purposes. Since the
southern half of our forecast area operates an
aggressive, proactive prescribed burn program,
this product will be issued year-round.

| Probability of Meeting or Exceeding Specific Temperature Thresholds |
The Probability of Meeting or Exceeding Specific
Temperature Thresholds (e.g. Freezing or 100
degrees) is a graphical display on the Internet
of the probability (in percent) that temperatures
will either rise above or fall below the desired
threshold in a given county Warning Area (CWA)
for the Day 1 and Day 2 forecast time periods. It
will be updated as necessary, but will be issued
at a minimum with each major Zone Forecast
package at 3 pm and 4 am local Pacific time. |
Carl Gorski |
| Probability of Freezing Temperatures |
The Probability of Freezing Temperatures product
will be a graphical display on the internet of
the probability (in percent) that overnight low
temperatures will fall to freezing or below
across the (PDT) County Warning Area (CWA) for
the ?tonight? and ?tomorrow night? time periods.
It will be updated as necessary, but at a minimum
with each major Zone Forecast issuance at 3 pm and
4 am local Pacific time. The product will be
issued seasonally in the fall from September 15th
until November 30th and in the Spring from March
15th until May 31st. |

| Dry Lightning Potential Index |
The Dry Lightning Potential Index (DLPI) is a
graphical product produced by forecasters at WFO
Las Vegas (VEF) using GFE/IFPS. Ratings of Dry
Lightning potential (numbered from 0 through 6)
for the next three days (today, tomorrow and the
next day) are calculated using forecasts of
boundary layer relative humidity and static
stability. The DLPI is intended to be used as
general guidance, primarily for planning
purposes. The DLPI is intended as a seasonal
product, issued from June through October, when
active wildfires are most likely to occur in our
forecast area |
Carl Gorski |
| Hours of Sunshine and Percent of Possible Sunshine Products |
The Hours of Sunshine and Percent of Possible
Sunshine Products will be graphical displays on
the Internet of the number of hours of sunshine
expected and the percent of total possible
sunshine expected across the (PDT) County Warning
Area (CWA). The products will be updated with
each major Zone Forecast issuance. At 4 AM local
Pacific Time, the forecasts will be for today and
tomorrow. At 3 PM local Pacific Time, the
forecasts will be for tomorrow and the day after
tomorrow. |

| Blowing Dust Potential Product |
The Blowing Dust Potential graphical forecasts are
designed to provide customers enhanced information
on the potential for blowing dust (low, moderate,
high, very high) to reduce visibilities below 1
statute mile during the next two days for areas
in the Pendleton County Warning Area (CWA) prone
to blowing dust (primarily the Columbia Basin and
Blue Mountain Foothills). |
