DISCUSSION AND OUTLOOK ---------------------- At 1000 AM CDT (1500 UTC), the center of Tropical Storm Grace was located near latitude 20.2 North, longitude 88.8 West. Grace is moving toward the west near 18 mph (30 km/h). A general westward to west-northwestward motion is expected today, followed by a general westward to west-southwestward motion at a slower speed over the weekend. On the forecast track, Grace is expected to continue to move across the Yucatan Peninsula today, and move over the southwest Gulf of Mexico late tonight through Friday. Grace will likely make a second landfall on the mainland coast of Mexico late Friday or early Saturday. Maximum sustained winds have decreased to near 65 mph (100 km/h) with higher. Additional weakening is possible while Grace moves across land today. Re-intensification is likely after the center reaches the Gulf of Mexico. Grace is forecast to be a hurricane when it makes its second landfall on the mainland coast of Mexico late Friday or early Saturday. Rapid weakening is expected after Grace moves inland over central Mexico. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure is 994 mb (29.36 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: Tropical storm conditions will continue to spread westward today across the northern Yucatan peninsula within the tropical storm warning area. Hurricane conditions are expected in the hurricane warning area in mainland Mexico by late Friday or early Saturday. Tropical storm conditions are expected within the tropical storm warning area in mainland Mexico by late Friday. RAINFALL: Grace is expected to produce the following rainfall amounts: Over north-central 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, northern Puebla and into Hidalgo...6 to 12 inches of rain with isolated maximum totals of 18 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 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. Elevated water levels will gradually recede along the coast of the Yucatan Peninsula during the next several hours. SURF: Swells generated by Grace will continue to affect portions of the western Caribbean today. High surf generated by Grace will begin to affect the southern Gulf of Mexico coastline over the weekend. These swells are likely to cause life-threatening surf and rip current conditions.
