DISCUSSION AND OUTLOOK ---------------------- At 1000 PM CDT (0300 UTC), the center of Tropical Depression Narda was located near latitude 20.6 North, longitude 105.2 West. The depression is moving toward the northwest near 21 mph (33 km/h), and this 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 emerge over the Pacific early Monday and move near or across the Islas Marias archipelago. Narda is then forecast to 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. Slow strengthening is forecast once the center moves back over the Pacific Ocean, and Narda is expected to become a tropical storm again Monday morning. The estimated minimum central pressure based on nearby surface observations is 1001 mb (29.56 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Narda is expected to produce total rain accumulations of 5 to 10 inches along the southwestern coast of Mexico from Guerrero to Nayarit, and 1 to 4 inches over Baja California Sur through Monday night. Isolated maximum amounts of 15 inches are possible from Oaxaca to Nayarit. 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. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 100 AM CDT. Next complete advisory at 400 AM CDT. $$ Forecaster Stewart NNNN
