The U.S. Department of State has a new travel warning system, giving danger spots around the globe rankings on a scale of one to four.
Five states in Mexico have been classified under the most dangerous ranking.
For the State Department, Mexico is level 2, which warns American travelers to be cautious while visiting.
Mexico City ranked level 2, but Arizona’s neighbor, Sonora, is level 3, meaning: Reconsider traveling to that state.
And five Mexican states are level 4, the highest rank. Those include: Colima, Guerrero, Michoacán, Sinaloa and Tamaulipas.
These are places where the U.S. government advises zero traveling, similar to warnings for Iraq and North Korea.
This travel warning replaces the one issued last August, which still used a system without rankings.
