Forecasted Basin-Average Accumulated Precipitation (RDPS - 84 hrs)

Canadian sub-basin level 84-hour accumulated precipitation forecasts from the Regional Deterministic Prediction System (RDPS). The data is aggregated from a ~10 km resolution weather model updated 4 times daily, produced by Environment and Climate Change Canada and provided by the Government of Manitoba. The dataset was last updated on March 18, 2026.

Use Cases

• Short-term flood forecasting based on forecasted precipitation accumulations.
• Resource allocation for emergency crews based on watershed-level risk identification.
• Adapting reservoir release schedules based on sub-basin precipitation forecasts.
• Planning urban drainage controls based on expected rainfall or snowfall.

Strengths

• Forecasts are updated 4 times daily, providing frequent data refreshes.
• Data is aggregated at the sub-basin level, which is a convenient unit for hydrological analysis.
• Based on the Regional Deterministic Prediction System (RDPS), a numerical weather model with ~10 km resolution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to open_canada, focusing on Canada and adjacent regions.
