Signals

WRSI Signals classify forecast instability (forecast_stress), whether weather matters now (seasonal_context) and cross-model consensus (model_agreement). They carry no forward or sizing claim.

Typical use cases​

They are useful for:

  • Judging how much weight to put on the latest forecast run
  • Framing seasonal weather relevance
  • Monitoring model disagreement

Signals are most informative when interpreted alongside short-term forecasts.

Accessing WRSI Signals​

from snowtrail import Snowtrail
client = Snowtrail(api_key="your-api-key")

# Fetch WRSI forecast stress signal
df = client.wrsi.forecast_stress(date_from="2024-01-01")

# All methods return pandas DataFrames
print(df.head())
