ATLANTA — Weather forecasters from NOAA's National Weather Service updated the seasonal forecast for the Atlantic Hurricane Season on Thursday. The new forecast, released August, includes 13 to 18 named storms, with five to nine of the storms becoming hurricanes and two to five becoming major hurricanes.

The National Hurricane Center is tracking two weather systems in the Atlantic Ocean – neither of which pose immediate risk to the United States – while Henriette and Ivo wax and wane in the Pacific Ocean.

Tropical Storms Henriette and Ivo are expected to develop into hurricanes in the Pacific, the National Hurricane Center says.
