The Uruguay Ministry of the Environment has been producing Hydrological Bulletins monthly since May 2023. They provide information on the hydrological status and outlook for the next 6 months for Uruguay.

This includes an overview of:

  • Status information:
    • Rainfall
    • Surface
    • River flows (including using the Standardised Streamflow Index)
    • Meteorological drought (using the Standardised Precipitation Index, SPI, for 6-month accumulation periods)
  • Outlooks:
    • River flow forecasts for 1 month, 3 month and 6 month lead times using the Ensemble Streamflow Prediction (ESP) method

This figure is from the Hydrological Bulletin for December 2023 and shows the hydrological status for 47 basins (on the vertical y axis) for the previous 18 months (on the horizontal x axis). It summarises the hydrological status across both space and time in one figure.
