The National Hurricane Center or NHC noted "Conventional satellite imagery show a large area of cold cloud tops near the center, and there is a hint of an eye in the first-light visible images. Microwave imagery indicates that the eye structure underneath the overcast has become better defined, with less evidence of dry air entrainment than seen yesterday."

At 11 a.m. EDT (1500 UTC), NHC reported the center of Hurricane Rosa was located near latitude 17.2 degrees north and longitude 115.4 degrees west. Rosa is far enough away from land so no coastal warnings or watches are in effect. Rosa is about 530 miles (855 km) southwest of the southern tip of Baja California, Mexico.
