Warning Criteria Threshold Analysis

Forecasting the forecaster's official decision.

4-6hr Lead Time on Official Calls

Overview

This pillar analyzes the specific criteria and historical tendencies of agencies like the NWS and NHC. It predicts when they will officially issue a warning or name a storm, which is often the key trigger for market movement.

What It Does

It monitors real-time meteorological data, such as wind speeds from reconnaissance aircraft and satellite intensity estimates. This data is then compared directly against the public, hard-line thresholds that agencies must meet to make an official declaration. The analysis also models the 'human factor' by quantifying an agency's historical conservatism or aggressiveness in similar situations.

Why It Matters

Prediction markets often resolve based on official declarations, not just the physical weather conditions. This pillar provides a crucial edge by anticipating the bureaucratic decision point, allowing you to act before an official announcement confirms what the raw data already suggests.

How It Works

The system continuously ingests data from sources like Hurricane Hunter flights and satellite algorithms. It then calculates the gap between current conditions and official warning criteria, such as the 39 mph sustained wind threshold for a tropical storm. Finally, it applies a historical 'buffer' value to estimate the probability of an official call within a set timeframe.

Methodology

The analysis compares real-time data, primarily from reconnaissance aircraft SFMR wind speeds and satellite ADT T-numbers, against official NHC/NWS thresholds. For example, it tracks if 1-minute sustained surface winds are likely to be reported at or above 39 mph for a Tropical Storm naming. The model incorporates a 'buffer analysis' which quantifies the typical margin the agency applies before a formal declaration, calculated from historical data of similar events.

Edge & Advantage

This pillar provides an edge by focusing on the institutional decision process, predicting the official announcement that moves markets, not just the weather event itself.

Key Indicators

  • Proximity to Official Thresholds

    high

    Measures how close current observational data (e.g., wind speed, pressure) is to the official criteria for issuing a warning or classification change.

  • Agency Conservatism Index

    medium

    A historical measure of an agency's tendency to delay or expedite a declaration compared to when raw data first meets the criteria.

  • Data Source Consensus

    low

    The level of agreement between different data sources, such as reconnaissance aircraft, satellite estimates, and doppler radar.

Data Sources

  • Provides real-time flight-level and surface-level wind data from Hurricane Hunter aircraft.

  • Advanced Dvorak Technique satellite data for estimating tropical cyclone intensity.

  • Official forecast discussions which often contain language hinting at future warnings or classifications.

Example Questions This Pillar Answers

  • Will the NHC name the next tropical depression by September 15?
  • Will a hurricane warning be issued for Miami-Dade County before Tuesday at 8 AM?
  • Will the Storm Prediction Center issue a 'Particularly Dangerous Situation' (PDS) tornado watch for Oklahoma today?
