Where and how do tropical storms usually form that affect the US?

Tropical storms that affect the U.S. typically form over warm ocean waters in the Atlantic and East Pacific regions, particularly during the Atlantic hurricane season from June to November. These storms develop when warm, moist air rises over the ocean surface, creating low-pressure systems that can intensify into tropical depressions and eventually hurricanes. The warm waters of the Gulf of Mexico and the Caribbean Sea are particularly conducive to storm formation, allowing these systems to gain strength before making landfall. Factors such as wind shear and the Coriolis effect also play a crucial role in their development and trajectory.
