A storm over the Atlantic Ocean currently named Tropical Depression Twelve is expected to become a major hurricane—which will be named Kirk once it reaches tropical storm strength—by the end of the week. The tropical depression is currently on the brink of strengthening into a tropical storm.

Tropical Storm Kirk (formerly Tropical Depression 12) formed over the Atlantic Ocean Monday morning and is forecast to become a "large and powerful hurricane" later this week, the National Hurricane Center said.

As Florida's Gulf Coast and several southeastern states grapple with the remnants and loss of Hurricane Helene -- a Category 4 storm that made landfall in the Big Bend Thursday -- the National Hurricane Center is monitoring several disturbances.
