While hurricane forecast cones are usually right, National Hurricane Center meteorologist Joel Cline says there is just no way to pinpoint the exact location of landfall with any certainty. Winds: Sustained or frequent winds gusts up to or in excess of 74 miles per hour are possible in the Hurricane Watch area Friday.

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 Helene has sparked weather warnings across the Azores, the Portuguese islands located 1,000 miles off the west coast of continental Europe. Helene will end up dying out over the open Atlantic, with no chance to push towards the U.S. Little change in strength is forecast during the next 12 hours as Helene remains over warm sea surface temperatures. A turn to the west-northwest is possible early next week if Isaac survives.

On Monday afternoon, the wind speeds were at approximately 70 miles per hour, when it was downgraded after having been initially classed as a Category 1 hurricane. This as Tropical Storm Isaac continues to weaken.

Rainfall totals of 50 to 100 millimetres are possible, as well as isolated amounts up to 150 millimetres, therefore, flash-flooding is likely over low-lying and flood-prone areas.

Meanwhile, Caribbean Airlines has announced that due to Tropical Storm Isaac flights BW 434 BW 435 Port-of-Spain to St. Lucia will be affected and passengers are advised to contact its reservation offices for rebooking on the next available service. Tropical storm warnings and watches have already been issued for the area.

States of emergency were declared in the Carolinas; Virginia; Washington, DC; and Maryland, where some coastal areas are still recovering from summer storms.

Florence is the most worrisome of the bunch as it lumbers toward the East Coast carrying the threat of a deadly 13-foot ocean surge and flooding rains.
