It's a rather complicated picture, as hot on Willa's major hurricane heels, is Tropical Storm Vicente which will bring even more rain during Tuesday night

Key Messages: Willa
1. A life-threatening storm surge is expected Tuesday along the coasts of the Isla Marias, and west-central and southwestern Mexico near the path of Willa. Residents should rush preparations to completion to protect life and property and follow any advice given by local officials.
2. Everyone in Isla Marias, and within the hurricane warning area along coast of west-central Mexico should prepare for life- threatening major hurricane winds associated with the core of Willa. Hurricane force winds will also extend inland across the mountainous areas of west-central Mexico as Willa moves inland.
3. Heavy rainfall from Willa is likely to produce life-threatening flash flooding and landslides over much of southwestern and west-central Mexico.




HAZARDS AFFECTING LAND NHC

STORM SURGE:  An extremely dangerous storm surge is likely along portions of the coast of southwestern Mexico by Tuesday or Tuesday night, especially near and to the south of where the centre of Willa makes landfall.  Near the coast, the surge will be accompanied by large and destructive waves.

RAINFALL:  Willa is expected to produce storm total rainfall accumulations of 6-12”, with local amounts to 18”,

WIND:  Hurricane conditions are expected within the hurricane warning area beginning Tuesday afternoon, with tropical storm conditions expected by Tuesday morning. 

SURF:  Large swells generated by Willa will continue to affect portions of the coast of southwestern and west-central Mexico during the next few days. These swells are likely to cause life-threatening surf and rip current conditions.

Willa - After landfall, shear and the mountainous terrain of Mexico will cause rapid weakening and dissipation of the cyclone.NHC 

For TS Vicente, the primary hazard will be heavy rainfall across portions of southern and southwestern Mexico, which could cause life-threatening flash flooding adding to whatever Willa brings.  Guerrero, Michoaca, Colima, and Jalisco in Mexico. This rainfall could produce flash flooding and landslides within mountainous terrain.
