Florence
Hurricane Florence is located about 710 miles southeast of Bermuda. Our forecast takes Florence northwestward and inland into the North Carolina coast early Friday morning as a strong category 3 hurricane. Florence may move very slowly once inland, which could result in extreme rainfall amounts and extensive flooding across eastern North Carolina and southeast Virginia. Please see our latest advisory on your StormGeo web portal for further details.

Helene
Tropical Storm Helene is located in the far eastern Atlantic south of the Cabo Verde Islands. Helene should track out to sea to the northwest and north once it passes the Cabo Verde Islands, where it will move over cooler waters and slowly dissipate. Please see our latest advisory on your StormGeo web portal for further details.

Isaac
Tropical Storm Isaac is a tiny storm located about 1375 miles east of St. Lucia. Isaac is predicted to strengthen into a hurricane over the next 24-36 hours as it tracks nearly due west. Our forecast takes the center in between the islands of Martinique and Dominica on Wednesday night, possibly as a very small hurricane. Isaac will be encountering rapidly increasing wind shear as it nears the Caribbean, which should lead to steady weakening as it passes through the islands and moves into the Caribbean. Isaac is predicted to dissipate in the south-central Caribbean in 6-7 days. Please see our latest advisory on your StormGeo web portal for further details.

Other Disturbances / Areas to Watch
Disturbance 37 has been identified over the northwest Caribbean. The disturbance is producing a large area of heavy squalls across the northwest Caribbean, but there are no indications that a circulation center is developing, and there is little or no model support for development. The disturbance will move into the south-central Gulf over the next 24-36 hours then track slowly northward and into the Texas coast by Thursday. Over the Northwest Gulf, the disturbance will produce squalls with wind gusts of 50-60 mph on Wednesday. The disturbance may bring heavy rain to the Texas coast by Thursday. The chances of this disturbance developing into a tropical depression or storm are about 20 percent.
