For a depiction\nof areas at risk, please see the National Weather Service Storm\nSurge Watch/Warning Graphic, available at hurricanes.gov. This is a\nlife-threatening situation. Persons located within these areas\nshould take all necessary actions to protect life and property from\nrising water and the potential for other dangerous conditions.\nPromptly follow evacuation and other instructions from local\nofficials.\n \nA Hurricane Warning means that hurricane conditions are expected\nsomewhere within the warning area. A warning is typically issued 36\nhours before the anticipated first occurrence of\ntropical-storm-force winds, conditions that make outside\npreparations difficult or dangerous. Preparations to protect life\nand property should be rushed to completion.\n \nA Tropical Storm Warning means that tropical storm conditions are\nexpected somewhere within the warning area within 36 hours.\n \nA Storm Surge Watch means there is a possibility of life-\nthreatening inundation, from rising water moving inland from the\ncoastline, in the indicated locations during the next 48 hours. For\na depiction of areas at risk, please see the National Weather\nService Storm Surge Watch/Warning Graphic, available at\nhurricanes.gov.\n \nInterests in the Yucatan Peninsula of Mexico and elsewhere along the\nU.S. northern Gulf Coast should closely monitor the progress of this\nsystem.\n \nFor storm information specific to your area, including possible\ninland watches and warnings, please monitor products issued by your\nlocal National Weather Service forecast office.\n \n \nDISCUSSION AND OUTLOOK\n----------------------\nAt 1000 AM CDT (1500 UTC), the center of Hurricane Isaias was\nlocated near latitude 23.7 North, longitude 90.2 West. Isaias is\nmoving toward the east-northeast near 10 mph (17 km/h).  A turn\ntoward the northeast is expected later today followed by a turn\nnorthward on Friday. On the forecast track, Isaias is expected to\npass to the north of the Yucatan Peninsula later today and make\nlandfall along the U.S. northern Gulf Coast within the warning area\nlate Friday or early Saturday.\n \nMaximum sustained winds have increased to near 85 mph (140 km/h) \nwith higher gusts.  Additional strengthening is expected through \nearly Friday, and Isaias should remain a dangerous hurricane as it \napproaches the northern Gulf Coast Friday night.\n \nHurricane-force winds extend outward up to 15 miles (30 km) from the\ncenter and tropical-storm-force winds extend outward up to 90 miles\n(150 km).\n \nThe estimated minimum central pressure is 975 mb (28.80 inches).\n \n \nHAZARDS AFFECTING LAND\n----------------------\nKey messages for Isaias can be found in the Tropical Cyclone\nDiscussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC.\n \nSTORM SURGE: The combination of a dangerous storm surge and the\ntide will cause normally dry areas near the coast to be flooded by\nrising waters moving inland from the shoreline. The water could\nreach the following heights above ground somewhere in the indicated\nareas if the peak surge occurs at the time of high tide...\n \nOcean Springs, MS to Indian Pass, FL...5-7 ft\nMobile Bay...5-7 ft\nIndian Pass, FL to Steinhatchee River, FL...4-6 ft\nMouth of the Mississippi River, LA to Ocean Springs, MS...3-5 ft\nSteinhatchee River, FL to Suwannee River, FL...3-5 ft\nSuwannee River, FL to Yankeetown, FL...2-4 ft\n \nThe deepest water will occur along the immediate coast near and to\nthe east of the landfall location, where the surge will be\naccompanied by large and dangerous waves. Surge-related flooding\ndepends on the relative timing of the surge and the tidal cycle, and\ncan vary greatly over short distances. For information specific to\nyour area, please see products issued by your local National Weather\nService forecast office.\n \nFor a complete depiction of areas at risk of storm surge inundation,\nplease see the National Weather Service Peak Storm Surge Graphic,\navailable at hurricanes.gov/graphics_at4.shtml?peakSurge.\n \nWIND: Hurricane conditions are expected within the Hurricane Warning\narea Friday night into early Saturday, with tropical storm\nconditions beginning on Friday. Tropical storm conditions are\nexpected in the warning areas on Friday and Friday night.\n \nGusty winds are possible in portions of the Yucatan Peninsula today.\n \nRAINFALL: Isaias is expected to produce rainfall amounts of 1 to 3 \ninches through Thursday across coastal portions of the eastern Bay \nof Campeche with isolated higher amounts possible in the states of \nCampeche and western Yucatan.\n\nFrom Friday through the weekend, Isaias is expected to produce \nrainfall amounts of 3 to 7 inches across the central U.S. Gulf Coast \nextending from far southeastern Louisiana to the Florida Big Bend \nregion. Localized totals up to 15 inches are possible, particularly \nwithin banding across the Florida Panhandle and Big Bend. Rainfall \namounts of 1 to 3 inches, with localized amounts up to 5 inches, are \npossible across much of the Southeast as far north as the Tennessee \nValley and the Carolinas. Flash and urban flooding is possible \nacross the region, with considerable impacts possible across much of \nsouthern Alabama and the Florida Panhandle into southwestern \nGeorgia. River flooding is also expected, some of which could be \nsignificant. \n\nFor a complete depiction of forecast rainfall associated with \nTropical Storm Isaias, please see the National Weather Service Storm \nTotal Rainfall Graphic available at\nhurricanes.gov/graphics_at4.shtml?rainqpf and the Flash Flood Risk \ngraphic at hurricanes.gov/graphics_at4.shtml?ero.\n \nTORNADOES: Isolated tornadoes will be possible Friday night in\ncoastal areas of Alabama and the Florida Panhandle and far\nsouthwestern Georgia. The tornado threat will continue Saturday for\neastern Alabama, Georgia and northern Florida.\n \nSURF: Swells will affect the western and northern portions of the\nYucatan Peninsula beginning later today and spread northward toward\nthe Gulf Coast on Friday. These swells are likely to cause\nlife-threatening surf and rip current conditions. Please consult\nproducts from your local weather office.\n \nA depiction of rip current risk for the United States can be found\nat: hurricanes.gov/graphics_at4.shtml?ripCurrents\n \n \nNEXT ADVISORY\n-------------\nNext intermediate advisory at 100 PM CDT.\nNext complete advisory at 400 PM CDT.\n \n"}
