The depression is moving toward the northwest near 15 mph (24 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 over the Gulf of California near or just offshore the coast of northwestern mainland Mexico through Tuesday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Some slight strengthening is forecast, and Narda is expected to become a tropical storm again later today. The estimated minimum central pressure is 1001 mb (29.56 inches). A pressure of 1002.8 mb (29.61 inches) was recently reported at Islas Marias. HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions should spread northward over the Tropical Storm Warning area today and Tuesday.

Colima, Michoacan, Guerrero...Additional 1 to 4 inches, isolated storm totals 10 inches. Baja California Sur, Sonora...1 to 2 inches. 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.
