Florence, Isaac, Helene – All Likely to Become Hurricanes Early Next Week

Right now Florence, Isaac and Helene are still Tropical Storms, but they are all headed to more favorable environments and will likely become hurricanes by Tuesday.

Florence is the storm of most concern with impacts along the Carolina coastline looking more likely. The storm is becoming better organized and rapid intensification over the next 12-36 hours is expected, as Florence moves into warmer water and an area of lower wind shear. It could become a major category 4 hurricane by Wednesday.

Models are in good agreement as Florence moves west northwest in the Atlantic. They diverge as the storm nears the Eastern coast, with some even showing the system staying out in the Atlantic just offshore.

There is still uncertainty in the exact track, intensity and impacts to the east coast as the storm is still several days out. But those along the east coast should monitor the storm and have their hurricane preparedness plan in place.

Isaac and Helene will both enter into areas of lower wind shear and are forecast to strengthen into category 2 hurricanes. Isaac will head due west towards the Lesser Antilles, arriving around Thursday. There is an area of higher wind shear in the Caribbean Sea that Isaac will contend with as it continues to move west.  Helene will head away from the Cabo Verde Islands and into the open Atlantic, making a turn towards the north by midweek.
