Marco is forecast to continue moving westward near the coast of Louisiana for the next day or so. Maximum sustained winds have decreased to near 35 mph (55 km/h) with higher gusts. Additional weakening is expected, and Marco is forecast to become a remnant low on Tuesday. The system is then forecast to dissipate by early Wednesday. HAZARDS AFFECTING LAND STORM SURGE: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide… Morgan City LA to Ocean Springs MS, including Lake Borgne…2-4 ft The deepest water will occur along the immediate coast in areas of onshore winds, where the surge will be accompanied by large and dangerous waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. WIND: Tropical storm conditions are expected to start by this afternoon in portions of the warning area. RAINFALL: Marco is expected to produce total rainfall accumulations of 3 to 5 inches with isolated maximum amounts of 10 inches across portions of the northeast and north-central Gulf coast through Tuesday. This rainfall may result in areas of flash, urban and small stream flooding in the area. SURF: Swells generated by Marco are likely to affect portions of the northern Gulf Coast for the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. TORNADOES: A couple of tornadoes will be possible today from southeast Louisiana to the western Florida Panhandle.   Tropical Cyclone 13L (Laura) According to the NHC Advisory 21…Laura is moving toward the west-northwest near 20 mph (31 km/h) and this general motion with some decrease in forward speed is expected over the next day or so. A turn toward the northwest is forecast by Wednesday, and a northwestward to north-northwestward motion should continue through Wednesday night. On the forecast track, the center of Laura will move away from Cuba and over the southeastern Gulf of Mexico overnight. Laura is then forecast to move over the central and northwestern Gulf of Mexico Tuesday night and Wednesday, and approach the northwestern coast of the Gulf of Mexico Wednesday night. Maximum sustained winds are near 65 mph (105 km/h) with higher gusts. Strengthening is expected, and Laura is foreast to become a hurricane on Tuesday. Additional strengthening is forecast on Wednesday, and Laura could be near major hurricane strength when it approaches the coast. Tropical-storm-force winds extend outward up to 175 miles (280 km) from the center. HAZARDS AFFECTING LAND RAINFALL: Laura is expected to produce the following storm total rainfall accumulations through Tuesday: Jamaica and Cuba: 4 to 8 inches, with maximum amounts of 12 inches. Cayman Islands: 2 to 4 inches, maximum amounts of 6 inches. Florida Keys, Turks and Caicos Islands, and the Northwest Bahamas: 1 to 2 inches. Across the Greater Antilles this heavy rainfall could lead to life-threatening flash and urban flooding, and the potential for mudslides. From late Wednesday into Friday, Laura is expected to produce rainfall of 5 to 10 inches, with isolated maximum amounts of 15 inches across portions of the west-central U.S. Gulf Coast near the Texas and Louisiana border north into portions of the lower Mississippi Valley. 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. WIND: Tropical storm conditions are expected to spread westward within the warning area in Cuba through today. Tropical storm conditions are expected in Little Cayman and Cayman Brac today. Tropical storm conditions are also expected within the warning area in the middle and lower Florida Keys and the Dry Tortugas this afternoon and tonight. SURF: Swells generated by Laura are affecting portions of Hispaniola, eastern Cuba, the southeastern Bahamas and the Turks and Caicos Islands. These swells are expected to spread across central and western Cuba, the central and northwestern Bahamas, and the Florida Keys today. TORNADOES: An isolated tornado will be possible later today into tonight across the Florida Keys. Latest satellite image of the Gulf of Mexico
