MIAMI (AP) — A hurricane warning was issued Tuesday for a portion of southern Mexico as Tropical Storm Erick gained strength in the Pacific Ocean, forecasters said.

The U.S. National Hurricane Center says Hurricane Erick has formed in the eastern Pacific on a forecast track where it could make landfall in Mexico.

Hurricane Erick is rapidly intensifying in the Eastern Pacific Ocean and is about 100 miles south-southeast of Puerto Angel, Mexico, and is now forecast to become a major hurricane, according to the National Hurricane Center (NHC).
