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.

The National Hurricane Center on Saturday increased the odds a new tropical wave that has ventured into the Atlantic will develop while also keeping track of a second system that could become the season’s next tropical depression or storm.

The National Hurricane Center has tagged a tropical wave off the coast of Africa for possible development. Invest 97-L is tagged by the NHC on Saturday as a large area of disorganized showers that has already developed off Africa's west coast.
