In late October 2010, the National Hurricane Center (NHC) began to monitor a weak area of disorganized weather along the southern periphery of a frontal system, associated with a broad surface trough east-northeast of Puerto Rico.[1] Supported by an upper-level low retrograding to its southwest, the system generated clusters of scattered showers and isolated thunderstorms, otherwise known as convection.[2] The activity gradually enhanced as environmental conditions within its encounter became more favorable over time.[3] Around 1200 UTC October 28, satellite imagery showed what appeared to be the formation of a surface low within the trough.
