Remnants Of Sara Discussion Number 19
NWS National Hurricane Center Miami FL AL192024
300 AM CST Mon Nov 18 2024

Satellite images and surface observations indicate that Sara no
longer has a well organized circulation, and therefore has
degenerated into a trough of low pressure. The trough is beginning
to emerge back over water in the southwestern Gulf of Mexico. While
strong upper-level winds are expected to inhibit tropical
development, the remnant vorticity and moisture could interact with
an approaching frontal system and contribute to heavy rainfall along
the northern Gulf Coast during the next couple of days.

This is the last NHC advisory on Sara. For more information on the
ongoing rainfall threat in southern Mexico/Central America and the
expected heavy rainfall along the U.S. Gulf Coast, see products
issued by the Weather Prediction Center and your local weather
office.

As the associated cold front pushes eastward through Tuesday, numerous
showers and thunderstorms interacting with a surge of moisture being
lifted northward from the Gulf of Mexico could contain intense rainfall
rates capable of producing flash flooding. Heavy rainfall is most likely
tonight across eastern Louisiana and southern Mississippi, with the threat
expanding east to the Florida Panhandle on Tuesday. Scattered flash floods
are most likely throughout low-lying and urban regions. Residents and
visitors are reminded to have multiple ways to receive warnings and never
drive across flooded roadways.
