There are now three hurricanes active within the Atlantic, according to updates from the US National Hurricane Center.
Hurricanes Florence, Isaac, and Helene, are all moving on various paths within the Atlantic, and are being monitored by the NHC and other official weather agencies.
Updates via the NHC are as follows:
Category 4 Hurricane Florence heading for US Southern coast
Florence exploded into a potentially catastrophic Category 4 hurricane Monday as it closed in on North and South Carolina, carrying winds up to 130 mph and water that could wreak havoc over a wide stretch of the eastern United States later this week.
The South Carolina governor ordered the state's entire coastline to be evacuated starting at noon Tuesday.
The storm's first effects were already being seen on barrier islands as dangerous rip currents hit beaches and seawater flowed over a state highway. Communities along a stretch of coastline that is vulnerable to rising sea levels due to climate change prepared to evacuate.
The storm's potential path also includes half a dozen nuclear power plants, pits holding coal-ash and other industrial waste, and numerous eastern hog farms that store animal waste in massive open-air lagoons.
By noon Monday, Florence was centered about 1,230 miles (1,985 kilometers) east-southeast of Cape Fear, North Carolina, and moving west at 13 mph (20 kph). Its center will move between Bermuda and the Bahamas on Tuesday and Wednesday and approach the coast of South Carolina or North Carolina on Thursday, the National Hurricane Center said.
Hurricane Isaac continues west toward Windward Islands
In an 11:00 am advisory on Monday, the NHC said there has been little change in strength as the storm continues west toward the Windward Islands.
At 1100 AM AST (1500 UTC), the center of Hurricane Isaac was located near latitude 14.7 North, longitude 43.9 West. Isaac is moving toward the west near 14 mph (22 km/h).
A westward motion with a slight increase in forward speed is expected through the end of the week. On the forecast track, Isaac should move across the Lesser Antilles and into the eastern Caribbean Sea on Thursday.
Maximum sustained winds are near 75 mph (120 km/h) with higher gusts. Additional strengthening is expected over the next day or two.
Weakening is forecast to begin by the middle of the week as Isaac approaches the Lesser Antilles.
Hurricane-force winds extend outward up to 10 miles (20 km) from the center and tropical-storm-force winds extend outward up to 45 miles (75 km).
The estimated minimum central pressure is 993 mb (29.33 inches).
Interests in the Lesser Antilles should monitor the progress of Isaac.
The Trinidad and Tobago Meteorological Service says Trinidad and Tobago will not be directly affected by Hurricane Isaac, however the islands may be impacted by feeder bands from the storm.
Citizens are advised to follow the Met Office for updates.
Hurricane Helene heading west then north, away from Caribbean
Meanwhile as of Monday midday, Hurricane Helene was located near latitude 14.6 North, longitude 30.0 West and continued moving toward the west-northwest near 16 mph (26 km/h).
A west-northwestward motion with a decrease in forward speed is expected through late Tuesday, followed by a turn toward the northwest and then toward the north-northwest on Wednesday and Thursday.
Maximum sustained winds have increased to near 105 mph (165 km/h) with higher gusts. Some additional strengthening is expected today, and Helene is forecast to become a major hurricane by tonight. Steady weakening is forecast to begin by late Tuesday.
Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 105 miles (165 km).
The estimated minimum central pressure is 974 mb (28.77 inches).
