Track Storms Marco and Laura With These Updating Maps


The Gulf Coast is bracing for a devastating one-two punch, with two major storms, Marco and Laura, forecast to make landfall in the coming days. It is very unusual for two storms to hit the same coastal area in rapid succession.

Laura and Marco are the earliest L- and M-named storms recorded in the Atlantic basin. The 2020 Atlantic hurricane season is currently on track to rival 2005, when Hurricane Katrina devastated New Orleans, as the busiest on record.

The National Hurricane Center has issued a hurricane warning for the coast between Morgan City, south of Baton Rouge in Louisiana, and the mouth of the Pearl River on the border between Louisiana and Mississippi.

Use the control at the top right to toggle between the likelihood of tropical-storm-force winds (more than 39 mph) and hurricane-force winds (more than 74 mph). Times shown are US Central Time for Marco and US Eastern Time for Laura.

Marco, which passed between Mexico’s Yucatán Peninsula and Cuba on Saturday, had been expected to make landfall in Louisiana as a hurricane. But by Monday morning, it had weakened to a tropical storm and was expected to move along the coast of Louisiana, heading in the direction of Galveston, Texas.

Still, the National Hurricane Center warned on Monday morning that it could cause storm surges of up to 4 feet between Morgan City in Louisiana and Ocean Springs, Mississippi .

Laura is currently forecast to move along the south of Cuba before turning to the north, crossing the Gulf of Mexico and making landfall in Louisiana at hurricane strength, probably in the early hours of Thursday morning.

This updating map shows the best predicted tracks for Marco and Laura superimposed over forecast rain for the next seven days. Marco is expected to cause 3 to 5 inches of rain, with isolated maximums up to 10 inches along parts of the Gulf Coast through Tuesday.

Over the weekend, Laura dumped large amounts of rain onto Puerto Rico, the Dominican Republic, and Haiti. Jamaica and Cuba are expected to receive 4 to 8 inches of rain, with isolated maximums of up to 12 inches.

When it reaches the Gulf Coast, Laura is expected to produce 5 to 10 inches of rain, with isolated totals of up to 15 inches in some places.

“This rainfall could cause widespread flash and urban flooding, small streams to overflow their banks, and the possibility of some minor river flooding across this region,” the National Hurricane Center warned on Monday morning.
