DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 900 AM MDT (1500 UTC), the center of Tropical Storm Newton was located near latitude 30.2 North, longitude 111.3 West. Newton is moving toward the north-northeast near 18 mph (30 km/h), and this motion is expected to continue until Newton dissipates tonight. On the forecast track, the center of Newton will move into southeastern Arizona this afternoon. Maximum sustained winds have decreased to near 50 mph (85 km/h) with higher gusts. Continued rapid weakening is forecast, and Newton should weaken to a tropical depression over southeastern Arizona by this evening and dissipate overnight. Tropical-storm-force winds extend outward up to 105 miles (165 km) mainly to the south and east of the center. The estimated minimum central pressure is 994 mb (29.36 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions will continue over northern portions of the Mexican state of Sonora through this afternoon and could spread into southeastern Arizona during the next few hours. Wind speeds atop and on the windward sides of hills and mountains are often up to 30 percent stronger than the near-surface winds indicated in this advisory, and in some elevated locations could be even greater. RAINFALL: 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 Wednesday night. This heavy rainfall may cause life-threatening flash floods and mud slides in areas of mountainous terrain. SURF: Swells associated with Newton over the Gulf of California will continue to subside during the day. NEXT ADVISORY ------------- Next intermediate advisory at 1200 PM MDT.
