Tropical Storm Marco is expected to strengthen into a hurricane Sunday before it is projected to hit Louisiana — while Tropical Storm Laura is set to barrel down the same path, also as a hurricane.

Hurricane warnings were issued from Morgan City, Louisiana to the mouth of the Pearl River as the two tropical storms move towards the Gulf Coast, according to the National Hurricane Center.

The projected tracks showed that both storms will be together in the Gulf on Monday, with Marco reaching Louisiana’s coast sometime midday and Laura making landfall Wednesday.

Marco is currently moving north at 13 mph from 395 miles south-southeast of the mouth of the Mississippi River.

Meanwhile, Laura was centered about 95 miles east of Port-au-Prince, Haiti, Sunday morning, with maximum sustained winds of 45 mph.

The storm took down trees and knocked out power Saturday to more than 200,000 people in Puerto Rico — then left 100,000 people without water in neighboring Dominican Republic.

It was also slamming Haiti and was forecast to move over Cuba on Sunday night or Monday.

If the storms coincide, it would be the first time two hurricanes have appeared in the Gulf of Mexico simultaneously in at least a century.

Louisiana Gov. John Bel Edwards asked President Donald Trump for a federal emergency declaration ahead of the potential double whammy.

“The cumulative impact of these storms will likely have much of Louisiana facing tropical storm/hurricane force impacts for a much longer period of time than it would with any one hurricane,” he wrote.
