(CNN) Powerful hurricane Willa has made landfall near Isla Del Bosque, Sinaloa, on the western coast of Mexico, approximately 50 miles south of Mazatlán.

The Category 3 storm will quickly weaken over the next 24 hours as it makes its way across the Sierra Madre range and becomes a rainmaker for northern Mexico and Texas on Wednesday.
