DISCUSSION AND OUTLOOK ---------------------- At 600 PM MDT (0000 UTC), the center of Tropical Storm Narda was located near latitude 25.0 North, longitude 108.4 West. Narda is moving toward the northwest near 20 mph (32 km/h), and this general motion is expected to continue with some decrease in forward speed during the next couple of days. On the forecast track, the center of Narda will move along the coast of northwestern mainland Mexico through Wednesday. Maximum sustained winds remain near 50 mph (85 km/h) with higher gusts. Little change in strength is expected this evening, but Narda should begin to weaken late tonight and Tuesday as more of the circulation intersects with land. Tropical-storm-force winds extend outward up to 60 miles (95 km) from the center. A wind gust to 43 mph (69 km/h) was recently measured by a private weather observing site in Paralelo Treinta y Ocho, Mexico, and a gust to 35 mph (56 km/h) was recently reported at the airport in Culiacan, Mexico. The estimated minimum central pressure is 998 mb (29.47 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions should continue to spread northward within the Tropical Storm Warning through Tuesday. RAINFALL: Narda is expected to produce the following rainfall accumulations through Tuesday: Sinaloa...Additional 2 to 4 inches, isolated storm totals 10 to 15 inches. Chihuahua and western Durango...1 to 3 inches. Sonora...1 to 2 inches. Baja California Sur...Up to 1 inch. This rainfall will cause life-threatening flash floods and mudslides, especially in mountainous terrain. SURF: Swells generated by Narda are affecting portions of the coast of southwestern Mexico. These swells are expected to spread northward and will likely cause life-threatening surf and rip current conditions along the west coast of mainland Mexico, along the east coast of Baja California Sur, and in the Islas Marias archipelago.
