According to the National Hurricane Center, based on the latest forecast track, each storm would be making landfall in Louisiana, west of New Orleans, with Marco landing Monday evening, and Laura less than 48 hours later.
Marco, which formed in the Gulf of Mexico Sunday afternoon, is expected to bring with it life-threatening storm surge and hurricane-force winds.
If Laura and Marco became hurricanes simultaneously in the Gulf of Mexico, it would be an unprecedented occurrence, though, based on the latest advisory’s paths and intensities, it is a long shot.
Both storm tracks are unusually close to each other. If and how the two storms will interact with each other are highly uncertain, forecasters said.
As of 2 p.m., Marco was located about 440 miles southeast of Layfayette, La., and was moving north-northwest at 14 mph with maximum sustained winds of 75 mph. A Category 1 hurricane forms when sustained winds are in the range of 74 to 95 mph.
Tropical Storm Laura’s forecast has it at hurricane strength on Tuesday and Wednesday. As of Sunday, it was churning through the Caribbean Sea, carrying with it, tropical storm conditions which are now threatening the Dominican Republic, Haiti and Turks and Caicos Islands.
For the rest of Sunday into Monday, the US National Hurricane Centre says Tropical Storm Laura is expected to make its way towards the United States.
The NHC said south-eastern sections of the Bahamas and Cuba will experience the effects of Laura within the next few hours. NHC placed Laura’s centre of circulation 95 miles (150km) east of the Haitian capital Port Au Prince.
Tropical storm warnings are in effect for the Dominican Republic, Haiti, Turks and Caicos Islands, South-eastern Bahamas and Cuba.
A tropical storm watch is in effect for central Bahamas and the Florida Keys.
Laura has maximum sustained winds around 45 mph (75km/h) with higher gusts. NHC said tropical storm force winds extend outward up to 140 miles (220km).
A 10-year-old girl was killed in Haiti today when a tree fell on a house in the town of Anse-à-Pitres, to the southeast of the capital, Port-Au-Prince, as Tropical Storm Laura lashed sections of the country.
In the neighbouring Dominican Republic, gusts of wind and the intense downpours have left more than a million homes without electricity.
The light and power company, Distribuidora de Electricidad del Este, confirmed that the loss of supply caused the shutdown of at least 103 circuits, affecting 578,000 customers.
In its update at 11 a.m. (local time), the Miami-based National Hurricane Center said the centre of Tropical Storm Laura was located near latitude 19.2 degrees north, longitude 73.2 degrees west. Laura is moving toward the west-northwest near 21 miles per hour (33 kilometres per hour), and this general motion with some decrease in forward speed is expected over the next couple of days.
Based on the forecast track, the centre of Laura will move near or over Cuba tonight and Monday, and move over the southeastern Gulf of Mexico Monday night and Tuesday.
Laura is expected to move over the central and northwestern Gulf of Mexico Tuesday night and Wednesday. .
