Gulf Coast Cyclones
• Gulf Coast cyclones
develop most frequently
during years when the subtropical
jetstream is a persistent feature in the upper troposphere over northern Mexico and the Gulf of Mexico.
•Subtropical jetstreams tend to be strong in El Nino years, therefore, Guld Coast cylcones are more common during El Nino years.
• Gulf Coast cyclones
follow two tracks:
(1) along the Gulf Coast and then northeast along the Atlantic Seaboard and (2) inland along the Mississippi and Ohio River Valleys.
