Subject: The National GIS Map Viewer (the Viewer) Tropical
Program Site
 Will Become Operational Effective on or about Tuesday,
 May 21, 2024

Effective on or about Tuesday, May 21, 2024 at 1300 Coordinated
Universal
Time (UTC), the National Weather Service (NWS) National Geographic
Information System (GIS) Map Viewer (the Viewer) tropical
program site
hosted on the Amazon Web Services public cloud will transition from
experimental to operational status. This is in addition to the
operational
sites from SCN 22-92:
https://www.weather.gov/media/notification/pdf2/scn22-
92_national_map_viewer_t2o.pdf.

The remaining program sites (Fire, Severe, Winter, Space, Climate,
Aviation, and Marine) will remain experimental at this time.  Once
the
remaining program sites are ready to transition to operational
status, an
additional Service Change Notice will be issued.

As NWS data and sources increase in size and frequency, providing the
capability for assimilating the data and making it more easily
accessible
and viewable by NWS users and partners/stakeholders is paramount.

Interactive, web-based geospatial products, including geospatial
services
and map viewers, are universal methods to serve many of these
assimilation
needs. Interactive maps driven by geospatial services can serve all
data
from rapidly updating products (e.g., Multi-Radar Multi-Sensor [MRMS]
data) to more traditional products (e.g., precipitation forecasts and
event-driven watches and warnings).  The NWS has developed the Viewer
and
program sites based on the aforementioned functional and data
requirements
provided by NWS staff based on feedback from their stakeholders.

The Viewer is the result of a NWS partnered effort with NOAAs
National
Ocean Service to leverage the Environment Response Management
Application
(ERMA) software and customize it to meet NWS functional
requirements.
The following GIS program sites are transitioning to Operational
status:



Tropical URL: https://viewer.weather.noaa.gov/tropical

The following GIS program sites will remain experimental at this
time:

Fire URL: https://viewer.weather.noaa.gov/fire

Severe URL: https://viewer.weather.noaa.gov/severe

Winter URL: https://viewer.weather.noaa.gov/winter

Space URL: https://viewer.weather.noaa.gov/space

Climate URL: https://viewer.weather.noaa.gov/climate

Aviation URL: https://viewer.weather.noaa.gov/aviation

Marine URL: https://viewer.weather.noaa.gov/marine

Technical functionality and the look and feel will be
consistent across
all the Viewer program sites, but each program site will feature data
most
relevant to the type of weather, water, and/or climate focus areas
represented by the program site.

Recent changes to the Tropical Program Site include:
1. Dynamic legend only displays the hazards in effect
2. Plain language field names (attributes)
3. Peak Storm Surge Graphics added as a new service
4. Improvements to Point Weather Forecast button functionality

Additional data and functionality will be added periodically in the
future.
