DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 300 AM MDT (0900 UTC), the center of Tropical Storm Newton was located near latitude 17.9 North, longitude 106.1 West. Newton is moving toward the north-northwest near 10 mph (17 km/h). A northwestward or north-northwestward motion with an increase in forward speed is expected later today and Tuesday. On the forecast track, the center of Newton will be near or over the southern tip of the Baja California peninsula Tuesday morning. Maximum sustained winds have increased to near 45 mph (75 km/h) with higher gusts. Strengthening is forecast during the next 36 hours or so, and Newton could be near hurricane intensity when it approaches the extreme southern Baja California peninsula Tuesday morning. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected to reach the coast within the hurricane warning area by Tuesday morning. Winds are expected to first reach tropical storm strength by late tonight, making outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. Hurricane and tropical storm conditions are possible within the hurricane watch area on Tuesday. Tropical storm conditions are expected within the tropical storm warning area along the southwestern coast of Mexico today. Tropical storm conditions are possible within the tropical storm watch areas by late Tuesday. RAINFALL: Newton is expected to produce total rainfall accumulations of 5 to 10 inches for coastal portions of the Mexican states of Michoacan, Colima, Jalisco, Nayarit, Sinaloa, as well as much of the state of Baja California Sur, with isolated maximum amounts of 15 inches through Tuesday night. These rains could produce life-threatening flash floods and mud slides, especially in areas of mountainous terrain. SURF: Swells generated by Newton are expected to increase near the coast of southwestern Mexico and the southern portion of the Baja California peninsula 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.
