Risk Assessment

Weather Shield's risk assessment system provides real-time evaluation of weather-related risks for your project sites. This guide explains how the risk assessment system works and how to interpret its results.

Risk Levels

Weather Shield uses a five-level risk categorization system:

typescript
type RiskCategory = 'minor' | 'moderate' | 'high' | 'severe' | 'extreme'; const riskThresholds = { extreme: 80, // Risk score ≥ 80 severe: 60, // Risk score ≥ 60 high: 40, // Risk score ≥ 40 moderate: 20, // Risk score ≥ 20 minor: 1 // Risk score > 0 };

Risk Score Calculation

Risk scores are calculated using multiple factors:

  1. Weather Conditions

    • Temperature extremes
    • Wind speed
    • Precipitation
    • Visibility
    • Storm proximity

  2. Site Type Multipliers

typescript
const siteTypeMultipliers = { solar_array: 1.2, // More sensitive to weather wind_farm: 1.3, // Most sensitive to weather hydroelectric: 1.1, // Moderate sensitivity coal: 0.9, // Lower sensitivity natural_gas: 0.9, // Lower sensitivity nuclear: 0.8, // Most resilient geothermal: 0.9, // Lower sensitivity biomass: 0.9 // Lower sensitivity };
  1. Active Weather Alerts
typescript
interface RiskAssessment { riskLevel: number; // 0-100 riskCategory: RiskCategory; primaryRiskFactors: string[]; }

Risk Visualization

Dashboard View

The dashboard provides several risk visualization tools:

  1. Risk Overview

    • Color-coded site cards
    • Risk level indicators
    • Trend arrows

  2. Risk Details

    • Contributing factors
    • Historical trends
    • Site comparisons

Color Coding

typescript
const riskColors = { extreme: 'text-destructive border-destructive', severe: 'text-destructive/80 border-destructive/80', high: 'text-warning border-warning', moderate: 'text-warning/80 border-warning/80', minor: 'text-blue-500 border-blue-500', normal: 'text-muted-foreground border-muted' };

Site-Specific Risk Factors

Solar Arrays

  • High Risk Conditions
    • Hail
    • High winds
    • Extreme temperatures
    • Heavy snow/ice

Wind Farms

  • High Risk Conditions
    • Extreme wind speeds
    • Lightning
    • Icing conditions
    • Turbulence

Hydroelectric

  • High Risk Conditions
    • Flooding
    • Drought
    • Ice formation
    • Debris

Risk Mitigation

Automated Actions

Weather Shield can trigger automated actions based on risk levels:

typescript
interface RiskAction { threshold: number; action: 'notify' | 'alert' | 'shutdown'; targets: string[]; message: string; } const riskActions: RiskAction[] = [ { threshold: 80, // Extreme risk action: 'shutdown', targets: ['operations', 'maintenance'], message: 'Critical weather risk detected - immediate action required' }, { threshold: 60, // Severe risk action: 'alert', targets: ['supervisors'], message: 'Severe weather risk - prepare for potential shutdown' } ];

Manual Actions

Recommended actions for each risk level:

  1. Extreme Risk

    • Immediate site shutdown
    • Personnel evacuation
    • Emergency procedures

  2. Severe Risk

    • Prepare for shutdown
    • Limit operations
    • Increase monitoring

  3. High Risk

    • Enhanced monitoring
    • Review procedures
    • Alert key personnel

  4. Moderate Risk

    • Regular monitoring
    • Standard procedures
    • Document conditions

  5. Minor Risk

    • Normal operations
    • Standard monitoring
    • Log conditions

Risk Reporting

Real-time Reports

  • Current risk levels
  • Contributing factors
  • Trend analysis
  • Site comparisons

Historical Analysis

typescript
interface RiskReport { timeframe: 'daily' | 'weekly' | 'monthly'; metrics: { averageRisk: number; peakRisk: number; riskDistribution: Record<RiskCategory, number>; incidents: { date: string; riskLevel: number; description: string; }[]; }; }

Best Practices

  1. Regular Review

    • Monitor risk trends
    • Adjust thresholds
    • Update procedures

  2. Documentation

    • Log all incidents
    • Record mitigation actions
    • Track effectiveness

  3. Team Training

    • Risk assessment understanding
    • Response procedures
    • Communication protocols

Troubleshooting

Common Issues

  1. Inaccurate Risk Levels

    • Verify weather data
    • Check site multipliers
    • Review alert status

  2. Missing Alerts

    • Check connectivity
    • Verify thresholds
    • Test notification system

  3. False Positives

    • Adjust sensitivity
    • Update thresholds
    • Review conditions
