Hurricane Polo made landfall in Baja California overnight and is expected to make a second landfall on the mainland of Mexico on Tuesday.
Polo slammed the Baja California Peninsula near Las Barrancas as a Category 2 hurricane, packing dangerous winds of 96 to 110 mph.
After making landfall around 11 p.m. local time, Polo was downgraded to a Category 1 storm as it trekked across the Baja and took aim at the Sonora region of mainland Mexico.

The hurricane’s remnants will eventually merge later Tuesday with an existing storm system and supercharge moisture across a large swath of the United States.
