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 Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. 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 1000 PM CDT (0300 UTC), the center of Hurricane Grace was located near latitude 19.8 North, longitude 85.6 West. Grace is moving toward the west near 18 mph (30 km/h). A general west- northwestward to westward motion is expected through Friday, followed by a general westward to west-southwestward motion. On the forecast track, Grace is expected to make landfall in the eastern Yucatan Peninsula during the next six to twelve hours, move across the Yucatan Peninsula on Thursday, and move over the southwest Gulf of Mexico late Thursday through Friday. Maximum sustained winds are near 80 mph (130 km/h) with higher gusts. Some strengthening is expected before landfall on the Yucatan peninsula. Grace is expected to weaken as it crosses Yucatan, but re-intensification is expected when the center reaches the Gulf of Mexico. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 140 miles (220 km). The latest minimum central pressure reported by an Air Force Reserve Hurricane Hunter aircraft is 988 mb (29.18 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: Hurricane conditions are expected within the warning area in the Yucatan Peninsula of Mexico late tonight or early Thursday, with tropical storm conditions beginning during the next few hours. Hurricane and tropical storm conditions will spread inland the Yucatan Peninsula during the day Thursday. Hurricane conditions are possible in the hurricane watch area in mainland Mexico by by late Friday, and tropical storm conditions are possible in the tropical storm watch area in mainland Mexico by late Friday. Tropical storm conditions are possible along the southern coast of Cuba within the watch area for the next several hours. RAINFALL: The system is expected to produce the following rainfall amounts: Over central and 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 central to northern Veracruz...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 and along the eastern mainland coast of Mexico Friday night or early Saturday. 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.
