12 Month Hydrologic Forecasts

---

YGS provides subregional to regional hydrologic outlooks that help you understand where water conditions are heading from tomorrow through the next year. Results are delivered as maps and time series with a clear confidence summary so you can tell what is more certain and what should be treated cautiously.

Many tools focus on what already happened or provide a single number without explaining confidence. YGS is designed for decision makers who need forward looking information and clear interpretation.

• Forecast first products from tomorrow through the next year
• Regional decision scale built for areas people manage
• Confidence included so you know what is solid versus what is uncertain
• Clear visuals that are easy to interpret and share

Designed for basins, counties, and districts. 

Typical resolution is about 0.25 degrees, roughly 15 to 20 miles across varying by region.

Best for regional planning and risk context.

• Forecast time series and maps for your region (tomorrow to 12 months) 
• Trend analysis showing where conditions are heading 
• Confidence summary that explains how reliable the forecast is for your region and timeframe
