15 July 2019 Outlook for the 2019/2020 season
The outlooks for 2019/20 seasonal determinations are based on historical flow records that have been adjusted to match climate conditions observed since 1975.
The scenarios for different inflow conditions were produced using the following terminology:
- Wet: Inflow volumes to major storages that are greater in 10 years out of 100
- Above Average: Inflow volumes to major storages that are greater in 30 years out of 100
- Average: Inflow volumes to major storages that are greater in 50 years out of 100
- Below Average: Inflow volumes to major storages that are greater in 70 years out of 100
- Dry: Inflow volumes to major storages that are greater in 90 years out of 100
- Very Dry: Inflow volumes to major storages that are greater in 95 years out of 100
- Extreme Dry: Inflow volumes to major storages that are greater in 99 years out of 100
The following tables summarise possible HRWS seasonal determinations through the 2019/2020 season.
