SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Watch is in effect for... * Lazaro Cardenas to Cabo Corrientes Mexico A Tropical Storm Warning is in effect for... * Tecpan de Galeana to Cabo Corrientes Mexico A Tropical Storm Watch is in effect for... * North of Cabo Corrientes to San Blas Mexico 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, generally within 48 hours. Interests elsewhere along the west-central coast of Mexico and southern portions of Baja California Sur should monitor the progress of Nora. Additional watches and warnings will likely be required for portions of these areas on Friday. 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 Tropical Storm Nora was located near latitude 14.1 North, longitude 102.6 West. Nora is moving toward the west-northwest near 12 mph (19 km/h). A turn toward the northwest is expected on Friday, followed by a northwestward or north-northwestward motion on Saturday and Sunday. On the forecast track, the center of Nora will approach the southwestern coast of Mexico Friday and Friday night and pass very near the coast Saturday and Saturday night. Nora will then approach the southern portion of Baja California Sur on Sunday. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Strengthening is forecast during the next few days, and Nora is expected to become a hurricane on Saturday. Nora is a large tropical storm. Tropical-storm-force winds extend outward up to 205 miles (335 km) from the center. The estimated minimum central pressure is 1001 mb (29.56 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Nora can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP4, WMO header WTPZ44 KNHC, and on the web at hurricanes.gov/graphics_ep4.shtml?key_messages. WIND: Hurricane conditions are possible within the hurricane watch area Saturday, with tropical storm conditions beginning on Friday. Tropical storm conditions are expected within the tropical storm warning area beginning early Friday. Tropical storm conditions are possible within the tropical storm watch area beginning on Saturday. RAINFALL: Tropical Storm Nora is expected to produce heavy rains over coastal sections of the Mexican states of Oaxaca, Guerrero, Michoacan, Colima, and Jalisco. Rainfall totals of 8 to 12 inches are forecast through this weekend with isolated maximum amounts of 20 inches possible. Life-threatening flash flooding and mudslides may occur. SURF: Swells generated by Nora are affecting the southern coast of Mexico and will spread northward to the southwestern coast of Mexico on Friday and into the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Watch is in effect for... * Lazaro Cardenas to Cabo Corrientes Mexico A Tropical Storm Warning is in effect for... * Tecpan de Galeana to Manzanillo Mexico 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. Interests elsewhere along the west-central coast of Mexico and southern portions of Baja California Sur should monitor the progress of Nora. Additional watches and warnings will likely be required for portions of these areas later tonight and on Friday. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 700 PM CDT (0000 UTC), the center of Tropical Storm Nora was located near latitude 13.7 North, longitude 102.2 West. Nora is moving toward the west-northwest near 11 mph (18 km/h). A motion toward the northwest and north-northwest is expected to begin later tonight and continue through Sunday. On the forecast track, the center of Nora will approach the southwestern coast of Mexico Friday and Friday night and be very near the coast Saturday and Saturday night. Nora will then approach the southern portion of Baja California Sur on Sunday. Maximum sustained winds have increased to near 45 mph (75 km/h) with higher gusts. Strengthening is forecast during the next few days, and Nora is expected to become a hurricane on Saturday. Nora is a large tropical storm. Tropical-storm-force winds extend outward up to 205 miles (330 km) from the center. The estimated minimum central pressure is 1001 mb (29.56 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Nora can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP4, WMO header WTPZ44 KNHC, and on the web at hurricanes.gov/graphics_ep4.shtml?key_messages. WIND: Hurricane conditions are possible within the hurricane watch area Saturday, with tropical storm conditions beginning on Friday. Tropical storm conditions are expected within the tropical storm warning area beginning later tonight or on Friday. RAINFALL: Nora is expected to produce heavy rains over coastal sections of the Mexican states of Oaxaca, Guerrero, Michoacan, Colima, and Jalisco. Rainfall totals of 8 to 12 inches are forecast through this weekend with isolated maximum amounts of 20 inches possible. As a result, life-threatening flash flooding and mudslides may occur. SURF: Swells generated by Nora are affecting the southern coast of Mexico and will spread northward to the southwestern coast of Mexico through the end of the week. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

Watches may be required for a portion of the northern Gulf coast later tonight or Friday morning. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 800 PM EDT (0000 UTC), the center of Tropical Storm Ida was located near latitude 18.0 North, longitude 80.1 West. The storm is moving toward the northwest near 13 mph (20 km/h), and this general motion should continue over the next few days. On the forecast track, the center of Ida will pass near or over the Cayman Islands tonight, the Isle of Youth and western Cuba Friday, and over the southeastern and central Gulf of Mexico Friday night and Saturday. The system is forecast to approach the U.S. northern Gulf coast on Sunday. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Steady strengthening is forecast during the next few days. Ida is forecast to become a hurricane when it is near western Cuba with additional strengthening expected while it moves over the Gulf of Mexico.

STORM SURGE: A dangerous storm surge will raise water levels by as much as 2 to 4 feet above normal tide levels in areas of onshore winds along the immediate coast of the Isle of Youth and near and to the east of where the center crosses the coast of western Cuba. Near the coast, the surge will be accompanied by large and destructive waves. WIND: Tropical storm conditions are expected in the Cayman Islands tonight, and are expected to reach the Isle of Youth and portions of western Cuba in the warning area on Friday. RAINFALL: Ida is expected to produce total rainfall accumulations of 6 to 10 inches with maximum totals of 15 inches across Jamaica. Rainfall totals of 8 to 12 inches with isolated maximum amounts of 20 inches are expected across the Cayman Islands and western Cuba, including the Isle of Youth. These rainfall amounts may produce life-threatening flash floods and mudslides. Ida may begin to bring rainfall and potential flooding impacts to the central Gulf Coast by early Sunday. SURF: Swells generated by this system will affect Jamaica, the Cayman Islands and Cuba tonight and Friday. These swells are likely to cause life-threatening surf and rip current conditions.
