Forecasters say Tropical Storm Erin has formed in the eastern tropical Atlantic Ocean as Hurricane Henriette is strengthening in the Pacific Ocean.

Henriette regained tropical storm strength in the Pacific Ocean well east of Hawaii on Saturday, but forecasters said it was still not expected to pose a threat to land.

Tropical Storm Henriette was strengthening in the central Pacific Ocean far northeast of Hawaii and could become a hurricane but posed no threat to land, the National Hurricane Center said Sunday.
