September 26, 2023 - V2.1.3
General Updates
10% Public FIM Services: The following services will have their sharing status updated to be public:
Additionally, the 3 inundation extent services above received the following updates:
- Each FIM service layer now has an "(EXPERIMENTAL)" suffix added to it to emphasize it is an experimental product.
- Removal of FIM polygons outside of CONUS
- New and improved service descriptions

HAND wiki page.
New Services
Medium-Range NBM 10 Day Max Coastal Inundation (Internal): Depicts the inundation extent of the peak National Water Model (NWM) total water level forecast over
the next 3, 5, and 10 days. This service is derived from the medium-range NBM configuration of the NWM over the contiguous U.S. Updated every 6 hours. The new service pipeline and map files will be
pushed with this deployment, but the services will not be available until NWM 3.0 goes live.
Bug Fixes
Description Fixes: Updated "7 ensemble members" language to "6 time-lagged ensemble members".
RFC Workflow Restructuring: This deployment will update our replace and route workflow to be more database focused and easier to troubleshoot going forward. Because of the new way replace and route is processed, some bug fixes associated with thresholds have been addressed and fixed.

New Services
Medium-Range NBM 10 Day High Water Arrival Time (Internal): Depicts the forecast arrival time of high water over the next 10 days. This service is derived from the
medium-range NBM configuration of the National Water Model (NWM) over the contiguous U.S. Shown are reaches that are
expected to have flow at or above the high water threshold over the next 10 days. Reaches are colored by the time
at which they are forecast to reach high water (calculated in 3 hour increments). High water thresholds
(regionally varied) were derived using the 40-year NWM v2.1 reanalysis simulation. Updated every 6 hours.

simulation. Updated every 6 hours.

at or above high water thresholds. High water thresholds (regionally varied) and AEPs were derived
using the 40-year NWM v2.1 reanalysis simulation. Updated every 6 hours.

Medium-Range NBM 10 Day Peak Flow Arrival Time (Internal): Depicts expected peak flow arrival times derived from the operational National Water
Model (NWM) medium-range NBM forecast. Shown are reaches that are expected to have flow at or above
the high water threshold over the next 3 and 10 days. Reaches are colored by the time at which
they are expected to be at their maximum flow within the forecast period. High water flows were
derived using a 40-year retrospective analysis of the NWM (v2.1). Updated every 6 hours.
Medium-Range NBM 10 Day Rapid Onset Flooding (Internal): Depicts forecast rapid onset flooding using the medium-range NBM configuration of the
National Water Model (NWM) over the contiguous U.S. Shown are reaches (stream order 4 and below)

at or above the high water threshold within 6 hours of that increase (all calculated in 3 hour
increments). Also shown are USGS HUC08 polygons symbolized by the percentage of NWM waterway
length (within each HUC08) that is expected to meet the previously mentioned criteria. High

Bug Fixes
Rapid Onset Flooding HUC Summaries: For the ROF HUC summary layer, we calculate the percentage of reach length flooded within the certain HUC. The value of the total possible reach length within a HUC was not correct and thus producing incorrect percentages. We have updated this value and the percentages look more reasonable now.
Short Range 48 Hour Max Inundation Extent - Puerto Rico: The SRF max inundation service for Puerto Rico was incorrectly joining flowlines to the processed data which was resulting in null stream orders. These null stream orders were causing the symbology to not work correctly and hiding all inundation.
RFC Service Status Routing Issues: The workflow for replace and route and the corresponding services takes a forecast and routes the status downstream until a new RFC defined forecast point is reached. When the new point is reached, the new forecast status (whether no forecast, no flooding, or action+) is then used. In some cases, forecasts are issued at sites that are not at defined forecast points but where events are occurring. In these cases, the max status ends up being "Undetermined" instead of the actual forecast status. We have updated our algorithm to use the RFC defined forecast points AND points where live forecasts are being issued so that actual forecast statuses are used.

General Updates
Naming Standardizing: We have gone through all of our services and established a standardized naming convention to facilitate easier navigation and better understand of what data is being viewed from the name.
Name changes can be found at the bottom of this notification section. Naming convention is as follows:

- Product (required): Name of the data product
- Domain (optional): Indicates the domain that is being processed. If no domain is present, then the service is for CONUS
- NOAA(optional): Indicates if the service is internal or public. All internal services end in "_noaa"
