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, in this case within the next 24 to 36 hours. 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 in the southern portion of the Baja California peninsula should monitor the progress of this system. Additional watches or warnings may be required later today or on Saturday. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 100 PM CDT (1800 UTC), the center of Hurricane Beatriz was located by an Air Force Reserve Hurricane Hunter aircraft near latitude 17.5 North, longitude 102.6 West. Beatriz is moving toward the northwest near 13 mph (20 km/h), and this motion with some decrease in forward speed is expected through early Sunday. A turn toward the west-northwest with an additional decrease in forward speed is expected on Sunday. On the forecast track, the center of Beatriz is expected to move near or over portions of the coast of southwestern Mexico later today through Saturday. Beatriz is then expected to move away from the west-central coast of Mexico Saturday night and Sunday. Preliminary reconnaissance reports and recent satellite images indicate that Beatriz continues to strengthen, and maximum sustained winds have increased to near 80 mph (130 km/h) with higher gusts. Additional strengthening is possible today and tonight if Beatriz's center remains over water. Weakening is expected to begin on Sunday. Hurricane-force winds extend outward up to 10 miles (20 km) from the center and tropical-storm-force winds extend outward up to 70 miles (110 km). The minimum central pressure reported by aircraft data is 992 mb (29.29 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Beatriz can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP2 and WMO header WTPZ42 KNHC and on the web at hurricanes.gov/text/miatcdep2.shtml WIND: Hurricane conditions are expected somewhere within the hurricane warning area today through Saturday. Hurricane conditions are possible within the hurricane watch area on Saturday. Tropical storm conditions are likely occurring in the tropical storm warning area, and are possible within the tropical storm watch areas Saturday or Saturday night. RAINFALL: Through Sunday, storm total rainfall of 3 to 5 inches, with maximum amounts of 8 inches, is expected across southern Mexico from Guerrero west-northwest to Nayarit from Beatriz. This rainfall could lead to localized flash flooding and mudslides. STORM SURGE: A dangerous storm surge is expected to produce significant coastal flooding in areas of onshore winds. Near the coast, the surge will be accompanied by large and destructive waves. SURF: Swells generated by Beatriz are forecast to spread northward along the southwestern coast of Mexico during the next day or so. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
