Stormwater Intelligence & Weather Alert Analysis (Dec 2025) This dataset provides a comprehensive log of meteorological alerts and stormwater intelligence data collected during late December 2025. It aggregates active weather warnings, watches, and advisories, categorizing them by severity, urgency, and hazard type. The dataset is designed to support environmental compliance monitoring, flood risk assessment, and post-event analysis of severe weather patterns (such as high winds, freezing spray, and marine hazards).

Dataset Features The dataset consists of structured event logs with the following key fields:

Event: The specific category of the weather event (e.g., High Wind Warning, Small Craft Advisory, Flood Watch).

Severity: The intensity level of the threat (e.g., Severe, Moderate, Minor).

Certainty: The probability of the event occurring (e.g., Likely, Observed, Possible).

Urgency: The time sensitivity of the required response (e.g., Expected, Immediate).

Headline: The official text summary of the alert issuance.

Area Description: Specific geographic regions or municipalities affected by the alert.

Sent: The timestamp (ISO 8601) when the alert was officially issued.

Expires: The timestamp (ISO 8601) when the alert is scheduled to end.

Distribution Format: CSV (Comma Separated Values)

Data Volume: 186 records (rows) across 8 columns.

Usage This dataset is ideal for a variety of applications:

Stormwater Management: Monitoring precipitation and runoff risks for environmental compliance.

Risk Assessment: Analyzing the distribution of "High Severity" vs. "Minor" weather events.

Operational Planning: Reviewing alert lead times (Urgency) and duration (Sent vs. Expires).

Coverage Geographic Coverage: United States (Multi-regional coverage including Alaska, California, Puerto Rico, and the Great Lakes region).

Time Range: December 19, 2025 – December 21, 2025.

Demographics: N/A (Environmental and Meteorological data).

Who Can Use It Data Scientists: For training models to predict alert severity based on event type.

Researchers: For academic studies on meteorological hazard frequency and response.

Municipal Planners: For retrospective analysis of regional hazard exposure.

Additional Notes: This dataset identifies a total of 186 alerts, with a significant focus on "Stormwater-Related Hazards" (Wind, Water/Flood, Marine). Approximately 22.6% of the recorded events are classified as High Severity (Severe or Extreme).
