Gulf Coast Cyclone:
Prior to Development
• Gulf Coast cyclones typically develop after a cold front or an arctic front move
across
the US and arrives at the Gulf Coast.
•Aloft, a large trough is often present over the entire eastern US, which typically develops in association with an earlier Rocky Mountain cyclone.
•A subtropical jetstream flows from the tropical Pacific Ocean, across Mexico and over the Gulf Coast.
