Tropical Storm Vance Strengthens, Will Threaten Mexico

Tropical Storm Vance continues to churn over the waters of the eastern Pacific Ocean after developing on Thursday afternoon.
The AccuWeather.com Hurricane Center is keeping a close eye on the system, located several hundred miles south-southeast of Acapulco.
Further strengthening will occur through this weekend as the tropical cyclone remains over the warm waters of the eastern Pacific and in an environment that lacks disruptive wind shear, which can shred apart tropical systems as evident with Tropical Cyclone Nilofar.
The system is likely to strengthen into a hurricane by Sunday.

Through this weekend, Vance will pose hazards only to shipping interests as it stays well south of mainland Mexico.
That will change next week as a turn to the north, then northeast is expected. The Mexican states of southern Baja California Sur, Sinaloa and Jalisco are being put on alert for a potential landfalling Vance around Tuesday of next week.
Cabo San Lucas, Mazatlan and Puerto Vallarta lie within this zone.
While Vance will likely be past its peak intensity when it comes onshore, it should still bring a danger of flooding rain, mudslides, damaging winds and pounding surf.

Residents and visitors to Manzanillo should also keep a close eye on this developing system. A sharper turn to the northeast could put the city and its state of Colima in its path.
However, even if Vance remains to the north, Manzanillo would still face rough surf and potential downpours.
The impacts from Vance may not stop when it reaches the coast. Its heavy rain may get drawn across northern Mexico and into the U.S. states of Texas and New Mexico.
All residents and visitors in western Mexico should continue to check back with AccuWeather.com as Vance takes shape and more precise details on its impacts unfold.
