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 National Hurricane Center said Erick was expected to rapidly intensify and become a hurricane by late Tuesday or early Wednesday.

The National Hurricane Center said Tropical Storm Dalila has formed in the Pacific and will continue strengthening in the next couple of days.

The eastern Pacific Ocean has spawned a new tropical storm, Dalila, which will swipe southern Mexico with flooding downpours and gusty winds.
