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

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