Hurricane Helene to affect all Azores islands - IPMA

The GOES-East weather satellite, which keeps a constant eye on the East Coast and the Atlantic, has captured some breathtaking images of Hurricane Florence, Tropical Storm Isaac and Hurricane Helene approaching the Americas (in that order).

It's not clear if the storm is expected to strengthen back into a hurricane after it hits the eastern Caribbean.

Some fluctuation in wind speeds are expected, and weakening forecast Thursday, but it's still expected to be a fierce storm triggering unsafe flooding.

On the forecast track, Isaac is forecast to move across the central Lesser Antilles and into the eastern Caribbean Sea later today, and then move across the eastern and central Caribbean Sea through the weekend.

Tropical storm warnings were issued for Martinique, Dominica, and Guadeloupe.

Helene is one of several major storms in the Atlantic at the moment, with Florence sparking mass evacuations as it heads towards landfall on the east coast of the US.

Gradual weakening is forecast during the next 72 hours. Tropical storm conditions are possible within the tropical storm watch area, also beginning late this morning.

Helene is among a glut of tropical storms brewing in the region, with mass evacuations under way in southern U.S. states as Florence barrels across Virginia and the Carolinas.

The storm is now around 530 miles southeast of Cape Fear, North Carolina, and is moving west-northwest at 17 mph.

Wind gusts of up to 65mph are forecast with up to 80mph possible in more exposed areas.

"There is a small chance that injuries could occur from large waves and beach material being thrown onto sea fronts".

And finally, the NHC says that swells generated by Isaac will begin to affect portions of the Lesser Antilles on Wednesday afternoon. These swells are likely to cause life-threatening surf and rip current conditions.
