For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials. A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. A warning is typically issued 36 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. A Hurricane Watch means that hurricane conditions are possible within the watch area. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. For storm information specific to your area in the United States, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. For storm information specific to your area outside of the United States, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 700 AM CDT (1200 UTC), the center of Tropical Storm Marco was located near latitude 24.2 North, longitude 87.1 West. Marco is moving toward the north-northwest near 13 mph (20 km/h). Marco is forecast to continue moving north-northwestward across the central Gulf of Mexico today and will approach southeastern Louisiana on Monday. A gradual turn toward the west with a decrease in forward speed is expected after Marco moves inland on Monday and on Tuesday. Maximum sustained winds are near 70 mph (110 km/h) with higher gusts. Some strengthening is anticipated and Marco is forecast to become a hurricane later today and be at hurricane strength when it approaches the northern Gulf Coast on Monday. Rapid weakening is expected after Marco moves inland. Tropical-storm-force winds extend outward up to 60 miles (95 km) from the center. The estimated minimum central pressure based on data from the Air Force Reserve Hurricane Hunter aircraft is 994 mb (29.36 inches). 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... Sabine Pass to Morgan City LA...2-4 ft Morgan City LA to Ocean Springs MS including Lake Borgne...4-6 ft Ocean Springs MS to the AL/FL Border including Mobile Bay...2-4 ft Lake Pontchartrain and Lake Maurepas...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 destructive waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. WIND: Hurricane conditions are expected within the hurricane warning area by midday Monday, with tropical storm conditions possible by early Monday. Tropical storm conditions are possible within the tropical storm watch area on Monday, and hurricane conditions are possible within the hurricane watch areas late Monday. RAINFALL: Marco is expected to produce rainfall accumulations of 2 to 4 inches with isolated maximum amounts of 6 inches across the Central U.S. Gulf coast through Tuesday. This rainfall may result in isolated areas of flash and urban flooding along the Central U.S. Gulf Coast. SURF: Swells generated by Marco are likely to affect portions of the northern Gulf Coast later today. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. TORNADOES: An isolated tornado will be possible early Monday morning near the southeast Louisiana coast. NEXT ADVISORY ------------- Next complete advisory at 1000 AM CDT. $$ Forecaster Latto
