DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 300 PM MDT (2100 UTC), the center of Hurricane Newton was located near latitude 25.8 North, longitude 111.5 West. Newton is moving toward the north-northwest near 18 mph (30 km/h). A turn toward the north is expected tonight with this motion continuing through Wednesday. On the forecast track, the center of Newton will pass over portions of Baja California Sur during the next few hours and then emerge over the Gulf of California. The center of Newton should reach the coast of northwestern Mexico early Wednesday and is expected to reach southeastern Arizona Wednesday afternoon. Maximum sustained winds have decreased to near 75 mph (120 km/h) with higher gusts. Little change in strength is expected before landfall in northwestern Mexico, followed by weakening after landfall. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 230 miles (370 km). The Mexican automated station at Loreto recently reported sustained winds of 42 mph (67 km/h) and a wind gust of 82 mph (131 km/h). The estimated minimum central pressure is 986 mb (29.12 inches). HAZARDS AFFECTING LAND ---------------------- WIND: For the Baja California peninsula, tropical storm and hurricane conditions continue to occur over much of the warned area of the southern portion of the Baja California peninsula. These hazardous wind conditions will spread northward during the remainder of today within the warning areas. Preparations to protect life and property should have been completed. For the Mexican mainland, hurricane conditions are expected within the hurricane warning area by early Wednesday morning. Preparations to protect life and property should have been completed. Tropical storm conditions are beginning over northwestern Mexico within the warning area, and these conditions will gradually spread northward throughout the day and into tonight. Tropical storm conditions could spread into portions of southeastern Arizona by Wednesday afternoon. RAINFALL: Newton is expected to produce total rain accumulations of 8 to 12 inches over the Mexican state of Baja California Sur, and 5 to 10 inches over the Mexican states of Sinaloa, Sonora, western Nayarit, and Jalisco through Wednesday. Isolated maximum amounts of 18 inches are possible in Baja California Sur. Moisture associated with Newton is expected to produce total rain accumulations of 1 to 3 inches with locally higher amounts over southeastern Arizona to southwestern and south-central New Mexico through Thursday. In all of these locations, heavy rain could cause life-threatening flash floods and mud slides, especially in mountainous terrain. STORM SURGE: A dangerous storm surge is expected to produce significant coastal flooding near and to the east of the center on the southern Baja California peninsula and mainland Mexico. Near the coast, the surge will be accompanied by large and destructive waves. Elevated water levels are also expected in areas of onshore wind flow. SURF: Large swells generated by Newton are expected to affect the coast of southwestern Mexico through tonight, but will begin to subside on Wednesday. Large swells are occurring along the coast of Baja California Sur and should spread northward through the Gulf of California today and Wednesday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
