Tropical Storm Vicente and Tropical Storm Willa off the southern coast of Mexico

10/20/2018 2:47:00 PM

Tropical Storm Vicente is a very small tropical cyclone off the southern coast of Mexico. Vicente over the next couple of days will be moving west into an environment favorable for the system to become better organized as convection fires near the center of circulation. However, interaction with Tropical Storm Willa, located to the west-northwest, and with land will probably limit just how strong Vicente becomes. Regardless of strength, heavy rain will spread over the coastal areas and mountains of Guerrero to Jalisco Monday into Tuesday night. Localized downpours may also persist along the coast of Oaxaca. Rainfall totals will average 4-8 inches with an AccuWeather Local StormMax™ of 12 inches. This will lead to life-threatening flash flooding and higher-terrain mudslides.

Meanwhile, Tropical Storm Willa is moving to the west into an environment of low wind shear and over warm waters. This will allow further strengthening of the system. Willa is expected to become a hurricane later tomorrow and likely become a major hurricane by midweek. The storm, along with Tropical Storm Vicente, will contribute to flooding downpours in southwestern Mexico into early next week before threatening the Mexican states of Sinaloa and Nayarit with widespread flooding rain, damaging winds and storm surge flooding around Thursday of next week. Rainfall totals will average 4-8 inches with an AccuWeather Local StormMax™ of 12 inches. This will lead to life-threatening flash flooding and higher terrain mudslides. This moisture could end up enhancing the development of more heavy, flooding rainfall for parts of Texas later next week.

The rest of the East Pacific remains relatively quiet as does the Central Pacific Basin. Additional new tropical development elsewhere across the East Pacific and across the Central Pacific is not expected through at least the middle of next week.
