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

The National Hurricane Center said a tropical storm is expected to form in the Pacific Ocean on Friday and continue strengthening on Saturday.

A tropical storm is a tropical cyclone that has maximum sustained winds of between 39 and 73 mph – a step above a tropical depression.

A typhoon changed its path and landed in southern China's Hainan island at a severe tropical storm level. Its maximum sustained winds is 30 meters (98 feet) per second.

Barbara is expected to continue diminishing through Tuesday. Tropical Storm Cosme is expected to weaken through Thursday morning. Both storms are being tracked through the eastern Pacific Ocean, off the coast of southwestern Mexico, according to the NHC.

Hurricane Barbara and Tropical Storm Cosme mark the second and third named storms of the Eastern Pacific hurricane season.

Tennessee agriculture officials toured storm-damaged areas, assessing recovery needs after Tropical Storm Helene.
