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
Map Service Geometry Queries: We have made the geometry field visible on the map services. This allows users to query map services to get feature geometry.

Updated Services

Public FIM Domain: The WFO individual boundaries have been dissolved to just show the overall outer boundary and added a missing area near Beaumont.

September 7, 2023 - V2.1.2

General Updates

RAS2FIM 1.18.0 Implementation: We will now be implmenting a hybrid HAND and HEC-RAS Inundation solution, prioritizing HEC-RAS models where we have validated and pre-processed them. To learn more about RAS2FIM, visit the OWP RAS2FIM wiki page. HAND 4.4.0.0 Implementation: We will be updating the HAND version to 4.4.0.0. To learn more about HAND, visit the OWP 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.

August 10, 2023 - V2.1.1

General Updates

NWM 3.0 Implementation: The NWM 3.0 will be deployed operationally soon. Check out this Public Information Statement for more information on the specific NWM updates.

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. Medium-Range NBM 10 Day Max High Flow Magnitude (Internal): Depicts the magnitude of the peak National Water Model (NWM) streamflow forecast over the next 3, 5 and 10 days where the NWM is signaling high water. This service is derived from the medium-range NBM configuration of the NWM over the contiguous U.S. Shown are reaches with peak flow at or above high water thresholds. Reaches are colored by the annual exceedance probability (AEP) of their forecast peak flow. 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 Max Inundation Extent (Internal): Depicts the inundation extent of the peak National Water Model (NWM) streamflow forecast over the next 3, 5, and 10 days where the NWM is signaling high water. This service is derived from the medium-range NBM configuration of the NWM over the contiguous U.S. Shown are reaches with peak flow 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. SRC Skill: Depicts USGS sites that have an official rating curve, symbolized by the "skill" of the synthetic rating curve compared to the official USGS rating curve. Each point is symbolized by the mean difference in Water Surface Elevation (WSE) between the two curves. Estimated Impacted Buildings: Depicts building footprints that intersect inundation extents. The source of the building data is the FEMA USA Structures dataset: https://gis-fema.hub.arcgis.com/pages/usa-structures (as of August, 2022). Occupancy type data is only available for AL, CA, FL, GA, LA, MS, NC, SC, TX, and VA at this time. Also shown are a relative density heatmap of potentially impacted buildings (based on extent), county, and HUC level summary layers. 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) with a forecast flow increase of 100% or greater within 3 hours, and which are expected to be 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 water thresholds (regionally varied) were derived using the 40-year NWM v2.1 reanalysis simulation. Updated every 6 hours.

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.

July 6, 2023 - V2.1.0

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:
(model type)_(forecast period?)_(max?)_(product)_(domain?)_(noaa?)
  • Model Type (required): Indicates what model data is being processes. i.e. ana, srf, mrf, rfc, static, etc
  • Forecast Period (optional): Indicates forecast period being analyzed
  • Max (optional): Indicates if the data being analyzed is the max value across the forecast or not
  • 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"
FIM 4.3.11.0 Implementation (NOAA Internal): All flood inundation mapping (FIM) and quality control (QC) FIM services will be updated from FIM version 4.3.3.4 to 4.3.11.0
