The East Pacific Ocean
Development expected soon south of Mexico
Updated: October 22, 2021 3:50 AM EDT
While there are currently no tropical systems in the eastern Pacific, we are monitoring an area of convection off the southern coast of Mexico for development Friday or Saturday.
A broad area of low pressure is beginning to form a few hundred miles south of Acapulco, Mexico, and is producing some disorganized showers and thunderstorms this morning. Environmental conditions are conducive for tropical development, and a tropical depression or storm can form as early as later today. With favorable environmental conditions expected through the weekend, additional strengthening into a hurricane seems probable.
There remains disagreement on the exact track of the system, with the storm either pushing westward into the open Eastern Pacific Ocean or pushing northward early next week into the mountains of Mexico. However, it is likely to bring at least some rain to coastal portions of Mexico no matter the track. The exact track of the storm will be determined by how quickly the storm strengthens today and Saturday. A quicker strengthening storm will likely allow the storm to curve into Mexico Sunday or Monday. A slower to develop storm will likely allow the storm to remain farther off the coast.
