Remnants of Patricia Add to Heavy Rain


Heavy rain is expected to spread east along the Gulf Coast and through the lower Mississippi Valley into Monday, potentially causing flooding problems in areas where rain persists the longest.

An upper-level low pressure system and an area of low pressure sliding east along the Gulf Coast are combining to deliver the drenching downpours. The surface low pressure system in the Gulf of Mexico formed partially in response to the mid- and upper-level remnants of Hurricane Patricia. Also involved is the leftover moisture from Patricia.
