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 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. Interests elsewhere in eastern mainland Mexico should monitor the progress of Grace. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 500 PM EDT (2100 UTC), the center of Hurricane Grace was located near latitude 19.7 North, longitude 83.7 West. Grace is moving toward the west-northwest near 16 mph (26 km/h). A general west-northwestward to westward motion is expected for the next several days. On the forecast track, Grace is expected to make landfall in the eastern Yucatan Peninsula Thursday morning, move over the Yucatan Peninsula on Thursday, and move over the southwest Gulf of Mexico Thursday night or early Friday. Maximum sustained winds are near 80 mph (130 km/h) with higher gusts. Some strengthening is possible before the center of Grace reaches the Yucatan Peninsula. Weakening will occur while the center moves over the Yucatan Peninsula on Thursday, with restrengthening expected when Grace moves over the southwest Gulf of Mexico on Friday. Hurricane-force winds extend outward up to 15 miles (30 km) from the center and tropical-storm-force winds extend outward up to 140 miles (220 km). Tropical-storm-force wind gusts were reported over portions of western Cuba this afternoon. The estimated minimum central pressure is 992 mb (29.30 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Grace can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2, WMO header WTNT42 KNHC and on the web at www.hurricanes.gov/graphics_at2.shtml?key_messages. WIND: Strong gusty winds are likely over portions of the Cayman Islands for the next few hours. Tropical storm conditions are possible along the southern coast of Cuba within the watch area for the next several hours. Hurricane conditions are expected within the warning area in the Yucatan Peninsula of Mexico late tonight or early Thursday, with tropical storm conditions beginning as early as this evening. RAINFALL: The system is expected to produce the following rainfall amounts: Over the Cayman Islands and central to northern portions of the Yucatan Peninsula, 4 to 8 inches of rain with isolated maximum totals of 12 inches are expected through Friday. Heavy rainfall from Grace will likely result in areas of flash and urban flooding Over the central to northern Veracruz state of Mexico, 5 to 10 inches of rain with isolated maximum totals of 15 inches are expected from Friday through Sunday. Heavy rainfall from Grace will likely result in areas of flash and urban flooding, and will also be capable of producing mudslides. STORM SURGE: A dangerous storm surge will raise water levels by as much as 3 to 5 ft above normal tide levels along the immediate coast near and to the north of where the center makes landfall in the northeastern Yucatan Peninsula late tonight or early Thursday. Near the coast, the surge will be accompanied by large and destructive waves. SURF: Swells generated by Grace will spread westward from Jamaica and the Cayman Islands to the southern coast of Cuba and the Yucatan Peninsula of Mexico through Thursday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 800 PM EDT. Next complete advisory at 1100 PM EDT. $$ Forecaster Pasch
