At 8 P.M. CDT Sunday, Hurricane Marco remains a category 1 storm with winds of 75 mph, and a minimum central pressure of 992mb continues its track North towards the LA Coast, now located 180 miles SE of the mouth of the Mississippi River. Landfall is expected within 24 hours near the mouth of the Mississippi River as a category 1 storm. Heavy rain has expanded Eastward from the center of the storm as far as Tallahassee, Florida.
Storm surge of 2 to 4 feet is likely from Morgan City, LA to the mouth of the Mississippi River. 3 to 5 feet of surge is possible for areas along both Lake Borgne & Lake Pontchartrain. 1 to 3 feet of surge is possible along the Alabama Gulf coast–near places like Mobile, Gulf Shores, & Orange Beach.
NO SIGNIFICANT IMPACTS EXPECTED in Central Alabama from Hurricane Marco. What we will likely see is outer bands of tropical rainfall traverse through the region, starting tomorrow afternoon & continuing through Tuesday. We may see an East breeze pick up to 10 to 15 mph, but the lion’s share of strong winds & flooding rain WILL stay South & Southwest of us.
Tropical Storm Laura continues strengthening as it rides along the coast of Cuba, now with maximum sustained winds of 60 mph and a minimum central pressure of 1000mb–down 4 millibars from the previous advisory. Laura is expected to become a category 2 storm by Wednesday, making landfall somewhere roughly about 100 miles West of where Marco’s landfall is expected.
The exact track & strength of Laura are still subject to change. This storm is still worth watching for us here in Central Alabama, as Laura will likely be stronger than Marco.
