This fact sheet describes a predictive failure regarding Hurricane John in 2006, where official forecasts failed to predict the storm's actual path through the Baja California peninsula, resulting in five deaths. The document attributes these errors to a critical lack of upper air sounding data and divergence between numerical models.

This fact sheet describes a project led by the Universidad Nacional Autónoma de México (UNAM) to improve the prediction and historical understanding of landfalling tropical cyclones in the Eastern Pacific (EPAC) basin, focusing on historical reconstruction, lightning patterns, and high-resolution modeling.

This fact sheet describes a research project led by the Universidad Nacional Autónoma de México (UNAM) aimed at improving the understanding and forecasting of tropical cyclones in the Eastern Pacific, particularly regarding their intensification, evolution, and the potential impacts of global warming.

This fact sheet describes how a lack of upper-atmosphere sounding data contributed to inaccurate trajectory and rainfall predictions for Hurricane John in 2006, leading to fatalities and flooding in Baja California, Mexico.

This IAI fact sheet analyzes the failure of hurricane track predictions for Hurricane John in 2006, which caused deaths and flooding in Baja California, Mexico. The failure is attributed to a lack of upper air sounding data and model divergence. The document advocates for increased transnational collaboration and adherence to WMO standards for weather balloon soundings to improve future forecasting.
