Coronal Mass Ejections (CMEs) are major drivers of space weather disturbances and have long been suspected to influence atmospheric conditions on Earth. This study presents a unified analysis of 49 storm events (years 1887-2025) to evaluate whether CME activity may act as a precursor for hurricane formation. The survey reveals that most hurricanes occur 2-12 days after a major CME. To complement this long-term survey, statistical regression models were developed for CME speed, storm number, and CME transit time. Regression results show weak but measurable correlations, with r ≈ -0.12 for CME speed vs. storm number, and r ≈ 0.17 for CME speed vs. transit time, indicating the need for more refined physical models. The study supports the hypothesis that solar eruptive activity including CME propagation and magnetic cloud arrival at 1 AU may influence Earth’s atmospheric processes and potentially trigger or modulate hurricane development. CME-based forecasting could thus provide a 2-7 day advanced warning, improving disaster preparedness.
