ATLANTA (AP) — The Latest on Hurricanes Florence and Isaac (all times local):
The National Hurricane Center says Isaac has become the fifth hurricane of the 2018 Atlantic season.
The Miami-based center said late Sunday that Isaac was about 1305 miles (2100 kilometers) east of the Windward Islands with maximum sustained winds of 75 mph (120 kmh). The storm was moving west at 14 mph (22 kmh) and expected to accelerate over the next 36 hours.
Hurricane-force winds extend outward up to 10 miles (20kilometers) from the center and tropical-storm-force winds extend outward up to 45 miles (75 kilometers).
A westward motion is forecast to continue through the end of the week, with Isaac expected to move across the Lesser Antilles and into the eastern Caribbean Sea Wednesday night or Thursday. Weakening is forecast to begin by the middle of the week.
Rapidly intensifying Hurricane Florence could strike a direct and dangerous blow anywhere from the Carolinas to the Mid-Atlantic region later this week.
Florence crossed the 74 mph threshold from tropical storm to a hurricane Sunday morning, and by evening its winds were up to 85 mph (140 kph) as the National Hurricane Center warned a hurricane hunter plane found the storm strengthening quickly.
As of 11 p.m. EDT, Florence was centered about 685 miles (1,100 kilometers) southeast of Bermuda, moving west at 7 mph (11 kmh). Its maximum sustained winds are at 90 mph (150 kmh). Drawing energy from the warm water, it could be a fearsome Category 4 with winds of 130 mph (209 kph) or more by Tuesday
