Tropical system developing along the Mexican Pacific Coast


US meteorologists say a tropical rainstorm located off the southwestern coast of Mexico is showing signs that it may soon develop into a tropical depression or the eastern Pacific’s next tropical storm.

Already, the rainstorm has brought impacts on the Mexican coastline. While still too disorganized to officially be considered a tropical depression, storm, or hurricane, intensifying thunderstorms were ongoing near and just off the coast, a sign that the system continues to develop and organize.

“Thunderstorms are producing heavy rain over part of the coastline near and south of Acapulco, which will continue through the day on Sunday,” AccuWeather Senior Meteorologist Alan Reppert said, also noting that the rainstorm was expected to gain wind intensity during that time.

The next tropical storm to form in the East Pacific basin will be given the name Kay.

With plenty of warm water to work with at its disposal, as well as conducive atmospheric conditions, AccuWeather forecasters expect this system to become a tropical storm before the weekend comes to an end. By Tuesday, forecasters say it is likely to become the eighth storm of the season to reach hurricane status in the East Pacific basin.

While areas of heavy rain will continue in southwestern Mexico over the next few days, a greater concern is focused along the Baja Peninsula. It is along the Baja Peninsula, especially in the elevated terrain, where the heaviest rain is forecast to fall.

Widespread rainfall amounts of 4-8 inches (100-200 mm) are possible on the Baja Peninsula. Higher amounts of 8-12 inches (200-300 mm) can also occur for portions of the peninsula, with an AccuWeather Local StormMax™ of 20 inches (500 mm).
