Project Overview

Analysis of the December 2025 atmospheric river event and resulting debris flows in Stehekin, WA. This project uses various APIs to characterize the climatic conditions and geological impacts of this extreme weather event.

Location

• Study Area: Stehekin, Washington (48.31°N, 120.66°W)
• Event Date: December 2025
• Context: Heavy rainfall on fire-burned land during atmospheric river event

Files in This Folder

• API_class.ipynb - Main analysis notebook with API requests and data visualization
• README.md - This file

Data Sources

• USDA SNOTEL: Lyman Lake station (Site ID: 606) for precipitation data
• National Weather Service API: Weather observations for Stehekin area (Station: STRW1)

Methodology

1. Identified relevant weather stations near Stehekin
2. Used APIs to retrieve precipitation and climate data for December 2025
3. Analyzed data to characterize the atmospheric river event

Key Findings

• In December of 2025, there is a peak of streamflow, which coincides with flooding and landslides in the surronding area

Dependencies

• Python 3.x
• requests
• pandas
• matplotlib

How to Run

1. Open API_class.ipynb in Jupyter or VS Code
2. Run cells sequentially to retrieve and analyze data
