DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 900 PM MDT (0300 UTC), the center of Hurricane Newton was located near latitude 21.3 North, longitude 109.0 West. Newton is moving toward the northwest near 16 mph (26 km/h), and this general motion is expected to continue through early Tuesday. A turn toward the north-northwest, and then to the north, are expected late Tuesday and Wednesday. On the forecast track, Newton should be near or over the southern tip of the Baja California peninsula early Tuesday morning, move over portions of the southern Baja California peninsula Tuesday, and move into northwestern Mexico on early Wednesday morning. Maximum sustained winds have increased to near 90 mph (150 km/h) with higher gusts. Additional strengthening is forecast tonight, before the hurricane reaches the southern Baja California peninsula. Gradual weakening is expected after Newton makes landfall. Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 160 miles (260 km). The estimated minimum central pressure is 979 mb (28.91 inches). HAZARDS AFFECTING LAND ---------------------- WIND: For the Baja California peninsula, winds are expected to reach tropical storm strength within the next few hours, with hurricane conditions expected by early Tuesday morning. These conditions will spread northward over the Baja California peninsula through Tuesday. Preparations to protect life and property should be near completion. For the Mexican mainland, tropical storm conditions are expected over northwestern Mexico within the warning area beginning Tuesday morning, and these conditions will gradually spread northward throughout the day. Hurricane conditions are possible within the Hurricane Watch area early Wednesday. RAINFALL: Newton is expected to produce rainfall totals of 5 to 10 inches for coastal portions of the Mexican states of Michoacan, Colima, Jalisco, Nayarit, Sinaloa and Sonora as well as much of the state of Baja California Sur, with isolated maximum amounts of 15 inches through Tuesday night. These rains could cause life-threatening flash floods and mud slides, especially in areas of mountainous terrain. Rainfall amounts of 1 to 2 inches are expected across portions of southern Arizona and southwestern New Mexico from late Wednesday into Thursday, with localized amounts of up to 3 inches possible. These rains could result in dangerous flash flooding. STORM SURGE: A dangerous storm surge is expected to produce significant coastal flooding near and to the east of where the center makes landfall on both the southern Baja California peninsula and mainland Mexico. Near the coast, the surge will be accompanied by large and destructive waves. SURF: Large swells generated by Newton are expected to affect the coast of southwestern Mexico through Tuesday, and begin to subside on Wednesday. Swells should increase across the southern and central portions of the Baja California peninsula today and Tuesday. These swells are likely to cause life-threatening surf and rip current conditions.
