HOLT, Fla., Sept. 8, 2018–Tropical Storm Isaac has formed in the mid Atlantic Ocean this afternoon.

Isaac is moving slowly west at 7 mph and is expected to continue on that track for the next two-to-three days.

Additional strengthening is forecast and Isaac could become a hurricane by Monday as the storm moves westward across the warm waters of the tropical Atlantic, according to the National Hurricane Center.

Tropical Storm Helene is also forecast to become a hurricane, but possibly sooner than Isaac.

Maximum sustained winds have increased to near 60 mph and additional strengthening is expected during the next few days.

Helene is moving toward the west near 13 mph and is expected to continue on this path through Sunday before gradually turning west-northwest with an increase in speed Sunday night through Tuesday.

In addition to the soon-to-be hurricanes, the NHC has also identified two low-development areas in the Atlantic near the Bahamas and Azores.

The one closest to the east coast of the United States is unlikely to develop due to wind shear.

The area closer to the Azores is expected to develop into a non-tropical area of low pressure in a few days.

Some slow tropical or subtropical development is possible by the middle of next week while the low moves eastward away from the United States.
