View In: ArcGIS JavaScript ArcGIS Online Map Viewer ArcGIS Earth ArcGIS Pro

Service Description: Depicts expected peak flow arrival times derived from the operational National Water Model (NWM) short-range forecast for Puerto Rico and the U.S. Virgin Islands. Shown are reaches that are expected to have flow at or above high water threshold flow over the next 48 hours. Reaches are colored by the time at which they are expected to be at their maximum flow within the forecast period. High water threshold flows and annual exceedance probabilities were derived from USGS regression equations found at https://pubs.usgs.gov/wri/wri994142/pdf/wri99-4142.pdf Updated every 12 hours. This service is for internal use only for NOAA employees and requires access to view. Please do not share externally without prior approval from OWP as this service is experimental and undergoing regular developmental changes. For feedback or questions please reach out to GID directly via slack at national-water-center-gid or national-water-center-fim pages or reach out directly to derek.giardino@noaa.gov
