MIAMI (AP) – Tropical Depression Nana fizzled out of tropical storm status Monday, a day after it formed off the west coast of Africa.

The disorganized system had maximum 35-mph winds as it wobbled slowly to the west-northwest.

Forecasters at the National Hurricane Center said Nana would continue to disintegrate into a low-pressure system on Tuesday.

But forecasters are watching another tropical depression, this one in the Caribbean, that could form into the season’s 15th named storm Tuesday.

If it does, it will be Tropical Storm Omar. The depression already brought pounding rain to parts of the Dominican Republic and Puerto Rico as it hovered in the southern Caribbean.

The official forecast track shows that depression moving northeast, through Puerto Rico on Wednesday and then out to sea without affecting other bodies of land.

A third system was developing off Mexico’s Gulf Coast late Monday.

Forecasters said they would send military aircraft into the weather mass Tuesday to determine whether it had reached tropical-depression status. If it were to become a named storm, assuming Omar forms, it would be called Paloma.
