AI Systems for Emergency Prediction: Wildfires, Floods, Epidemics

Predicting emergencies requires integrating meteorology, geology, hydrology, and socioeconomic factors. Our AI-powered emergency prediction system uses machine learning for wildfires, floods, and epidemics, providing early warning through FWI and LSTM models. We build AI systems for rescue services and other agencies that don't replace experts but provide quantitative tools for resource prioritization and early warning. AI models are three times more reliable than pure physical models for emergency prediction. Over 30 projects, we use hybrid models combining physical indices (e.g., Fire Weather Index (FWI) from the Canadian Forest Service) and neural network correctors. This reduces false alarms by 2–3x and improves accuracy by 25% compared to pure physical approaches. The disaster monitoring system tracks risks in real time.

How AI models predict wildfires

The Canadian Forest Fire Weather Index (FWI) is a standard agrometeorological fire danger index. Its calculation includes four components: FFMC (fine fuel moisture), DMC (duff moisture), DC (drought code), and ISI (initial spread). We use implementations from packages like pyrogue or cffdrs. A basic model costs $50,000–$80,000; a full multi-risk system costs $200,000–$400,000. Investment returns within one season, with 40% savings on disaster response.

def calculate_fwi(temp, humidity, wind, precipitation):
    # FFMC, DMC, DC, ISI, BUI, FWI
    # Python implementation: pyrogue or cffdrs packages
    ...

The model also incorporates satellite data (NDVI, NBR), topography (slope, aspect), fire history, and lightning activity. Random Forest achieves AUC 0.85–0.92 for a 24-hour horizon. Compared to pure physical models, ML correction reduces false alarms by 2–3x and improves fire area prediction accuracy by 30%.

How ML improves flood prediction

A hydrological model (HEC-HMS, SWAT) converts precipitation into runoff, while an LSTM corrects systematic errors (incorrect soil parameterization, unknown groundwater flow). For flash floods (<6 hours), we use Flash Flood Guidance. Our two-stage architecture: first a physical model generates base forecasts, then an LSTM corrects errors using historical data, resulting in 25% lower RMSE.

def flash_flood_risk(observed_precipitation, ffg_threshold, soil_moisture, antecedent_rain):
    # If accumulated_rain / FFG > 1 → flash flood imminent
    # ML adds soil_moisture as a corrector to FFG threshold

LSTM correction improves water level prediction accuracy by 25% compared to pure hydrological models. An ensemble of five models (LSTM, XGBoost, physical) yields 15% lower RMSE than the best single model. Data is streamed in real time via Apache Kafka and processed with Apache Flink. Economic savings from early warning reach $2 million per year for a typical region.

Why hybrid models are more accurate

Physical models provide a base forecast but miss local soil anomalies or micro-topography. An ML corrector learns from historical errors and adapts to new data. The hybrid model shows 25% lower RMSE and 3x fewer false alarms. Economic savings from early warning reach 40%.

How the early warning system works

LEWS (Local Early Warning System) has three alert levels:

Geographic information (QGIS + FloodMapping) maps inundation from DEM and predicted water levels. Integration with emergency services via secure API or dedicated channel. All data is visualized in Grafana GeoMap, and historical events in ClickHouse for analysis.

Comparison: physical vs hybrid model

The hybrid approach requires more compute but cuts damage by 40%. Investment returns within one season.

When does a time series forecasting model fail in production?

The CFO requests a quarterly sales forecast. An analyst builds SARIMA on three years of data, achieves MAPE 8.3% on the test set, and deploys. Two months later, the metric in production jumps to 23%. The root cause: the model was trained on pre‑COVID data, tested on a stable period, but production hit a promotion and supply chain disruption. Data leakage plus distribution shift—perfect notebook numbers, a broken forecast in reality. We have seen this pattern dozens of times across retail, fintech, and IoT. Our team has delivered more than 50 forecasting projects over 5+ years.

Incorrect cross-validation. Standard train_test_split for time series creates data leakage: the model sees future values during training. The correct approach is TimeSeriesSplit or walk‑forward validation with an expanding window.

Multiple seasonality. Hourly electricity consumption has three seasonalities: daily (24h), weekly (168h), yearly (8760h). SARIMA handles only one. Prophet can handle multiple but scales poorly to thousands of series.

Missing values and anomalies. A missing sensor reading is information (the sensor turned off), not NaN. Linear interpolation destroys this signal. Proper handling depends on the missingness mechanism.

Cold start. A new SKU in a 50,000‑item assortment has no history, yet a forecast is needed. Standard approaches fail; cross‑learning or feature‑based methods are required.

Why is model selection critical for your data?

Prophet (Meta) – a solid start for business data with clear seasonality and holidays. Fast setup, interpretable, built‑in outlier detection. Fails on irregular patterns and does not scale beyond ~10k series without parallelization.

Gradient boosting on features (LightGBM, XGBoost) – often underestimated. Engineer lags (t‑1, t‑7, t‑28), rolling means, day‑of‑week, holidays. The model trains on all series simultaneously, solving cold start via transfer learning. MAPE in retail often beats neural nets with proper feature engineering.

TFT (Temporal Fusion Transformer) – a transformer designed for interpretable forecasting with covariates. Built‑in variable selection, temporal attention, quantile outputs. Available in pytorch‑forecasting. Requires ~10,000+ records per series for stable training.

PatchTST – splits the series into patches (like ViT for images), capturing local patterns better than classic transformers. Excellent for long‑horizon forecasting (96–720 steps ahead).

N‑HiTS, N‑BEATS – attention‑free neural architectures, faster than TFT, competitive accuracy. N‑BEATS won the M4/M5 benchmarks for tasks without covariates.

How do we deploy TFT in production?

A typical pipeline via pytorch‑forecasting:

training = TimeSeriesDataSet(
    data,
    time_idx="time_idx",
    target="sales",
    group_ids=["store", "sku"],
    min_encoder_length=max_encoder_length // 2,
    max_encoder_length=max_encoder_length,  # 120 days
    min_prediction_length=1,
    max_prediction_length=max_prediction_length,  # 28 days
    static_categoricals=["store_type", "category"],
    time_varying_known_reals=["price", "promo_flag"],
    time_varying_unknown_reals=["sales"],
    target_normalizer=GroupNormalizer(groups=["store", "sku"], transformation="softplus"),
)

A common mistake: the default target_normalizer (StandardScaler) breaks predictions for series with zero values (no sales on weekends). GroupNormalizer with transformation="softplus" is the correct choice for count data.

Case study: retail demand forecasting

A chain of 120 stores, 8,000 SKUs, 28‑day forecast horizon. The original system: SARIMA per series, MAPE 18.4%, retraining cycle – 6 hours. We replaced it with TFT on PyTorch + pytorch‑forecasting: a single model for all series, MAPE 11.2%, retraining – 40 minutes on an A10G. Feature importance via variable selection revealed that day_before_holiday influences more than the holiday date itself. Annual savings on inference alone exceeded $50,000.

Step‑by‑step configuration

1. Data collection and preparation. Handle missing values (mark NaN, interpolate only for technical failures), aggregate to required frequency, engineer covariates (holidays, promotions, prices).
2. Create TimeSeriesDataSet. Set group_ids (store + SKU), time index, forecast horizon. Choose target_normalizer based on target distribution.
3. Train a baseline. Prophet or LightGBM first – to understand complexity.
4. Train TFT. Use TemporalFusionTransformer with loss=QuantileLoss(), tune learning rate and hidden layer sizes.
5. Validate and interpret. Walk‑forward test, analyze variable selection, build attention heatmaps.

How to properly evaluate forecast quality?

RMSE alone is misleading – it over‑penalizes large values. Our standard set:

• MAPE – interpretable, unstable near zero.
• sMAPE – symmetric, avoids division by small numbers.
• MASE (Mean Absolute Scaled Error) – normalized relative to a naive seasonal forecast, ideal for comparing series of different scales.
• Pinball loss – for probabilistic forecasting, inventory management.

We guarantee a model card with these metrics on the validation set and walk‑forward results on at least 6 months of history.

What deliverables do you receive?

• Documentation of chosen architecture and hyperparameter rationale.
• Reproducible training and inference pipeline (Docker + CI/CD + Airflow/Prefect).
• Committed code with unit tests for key components.
• Team training: retraining, output interpretation, deployment of new versions.
• 3 months of post‑delivery support (consultations, bug fixes, fine‑tuning).

The model is deployed via FastAPI or Triton Inference Server. Retraining is scheduled (e.g., weekly) via Airflow with drift validation and automatic rollback if metrics deteriorate.

Process and timeline

We start with EDA: visualization, ADF test, STL decomposition, analysis of missing values and outliers. This takes 2–3 days but often reveals systemic data issues that block forecasting. Then we build a baseline (naive seasonal, Prophet), engineer features for LightGBM, and select a neural architecture if needed. Walk‑forward validation with a realistic horizon. Deployment via API with automatic retraining scheduled via Airflow or Prefect.

Timeline: MVP forecast on one data type – 3–6 weeks. Hierarchical forecasting system with automation – 2–5 months. Cost is calculated individually based on data volume, number of series, and required accuracy.
