Enhancements that are being made to the NWS gateway to hydrologic web resources are or will be available at:


Enhancements that have been recently implemented include the following:


1. Forecast issuance time on hydrographs is shown in bold font,

   making it more prominent and easy to see.


2. Text box in the upper left corner of display no longer

   overwrites the observed/forecast hydrograph or crest label  



3. USGS site number is provided in the NWS RSS feeds/xml files,

   if applicable.


4. Up to two notes can be shown below a hydrograph.


5. RSS feeds include the highest forecast value from the entire

   available forecast duration, not just the highest forecast

   value in the first 48 hours.


6. RSS feeds display flow and flood flow when the primary data

   is flow.

   hydrograph web page.


Enhancements that will be implemented by February 29, 2012 include:



1. River/stream locations that are color-coded according to

   flood status will be plotted on Google Maps. Users will be

   able to zoom, pan, and view this information across different

   regions, including NWS WFO Hydrologic Service Areas, NWS River

   Forecast Center areas of responsibility,

   and water resources regions.    


2. Region-specific web pages showing locations whose flood status

   is color-coded according to the maximum stage/flow forecast

   within 48 hours will now have a slider bar that allows users

   to display flood status according to the maximum level

   forecasted within 1 to 10 days. The availability of flood

   status information will depend on the forecast duration 

   provided by River Forecast Center guidance.


3. Observed precipitation shapefiles will include metadata fields

   for both the valid date and date/time the file was created or
