The tropical cyclogenesis (TCG) of Atlantic Hurricane Cindy (2005) was investigated to study environmental conditions preceding mesoscale vortex development in the Intra-Americas Sea (IAS; i.e., the Gulf of Mexico and Caribbean Sea) using the ERA-Interim Reanalysis pressure level data. Major findings include that the development of a mesoscale vortex occurred downward over Central America due to 600 hPa level enhanced winds downstream of southeasterly winds from northern South America, triggering Cindy's TCG in a few days. The contribution of midlevel enhanced winds should be noted as a potential precursor of other TCGs in the IAS.
