DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 600 AM MDT (1200 UTC), the center of Tropical Storm Newton was located inland over the Mexican state of Sonora near latitude 29.6 North, longitude 111.6 West. Newton is moving toward the north near 18 mph (30 km/h), and a turn toward the northeast is expected over the next day or so. On the forecast track, the center will move over extreme northwestern Mexico this morning and into southeastern Arizona this afternoon. Maximum sustained winds have decreased to near 60 mph (90 km/h) with higher gusts. Rapid weakening will continue today as the center moves farther inland, and Newton should weaken to a tropical depression later today and dissipate by early Thursday. Tropical-storm-force winds extend outward up to 150 miles (240 km) mainly to the south and east of the center. An automated station well inland east of Bahia Kino reported a sustained wind of 45 mph (72 km/h) with a gust to 64 mph (103 km/h) a couple of hours ago. Hermosillo International Airport has reported a wind gust as high as 50 mph (85 km/h). The estimated minimum central pressure is 991 mb (29.26 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions will continue over portions of the Mexican state of Sonora this morning, but winds should subside by this afternoon. Tropical storm conditions could spread into portions of southeastern Arizona later today. RAINFALL: Rains associated with Newton are moving away from the Baja California peninsula. Newton is expected to produce total rain accumulations of 3 to 6 inches, and possible isolated maximum amounts of 10 inches, over the Mexican state of Sonora. Moisture associated with Newton is expected to produce total rain accumulations of 1 to 3 inches with locally higher amounts over southeastern Arizona and southern New Mexico through Thursday. This heavy rainfall may cause life-threatening flash floods and mud slides in areas of mountainous terrain. STORM SURGE: Storm surge could continue in areas of onshore winds during the next few hours, but water levels are expected to diminish during the day. SURF: Swells associated with Newton over the Gulf of California will begin to subside. NEXT ADVISORY ------------- Next complete advisory at 900 AM MDT. $$ Forecaster Berg
