DISCUSSION AND OUTLOOK ---------------------- At 1100 AM MST (1800 UTC), the center of Tropical Depression Nine-E was located near latitude 19.5 North, longitude 107.7 West. The depression is moving toward the northwest near 7 mph (11 km/h). A northwestward to north-northwestward motion is expected through early Friday, followed by a turn toward the north and a slight decrease in forward speed by Friday night. On the forecast track, the center of the cyclone should pass near or over Baja California Sur Friday or Friday night before emerging over the southern Gulf of California late Friday night. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Some strengthening is forecast during the next 24 to 36 hours, and the depression is forecast to strengthen to a tropical storm later today. After that, slight additional strengthening is possible before the system reaches the southern Baja California peninsula. The estimated minimum central pressure is 1002 mb (29.59 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for the depression can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP4 and WMO header WTPZ44 KNHC. RAINFALL: Tropical Depression Nine-E is expected to produce 4-6 inches of rain with localized higher amounts up to 8 inches across the coastal areas of Michoacan, Colima, and Jalisco through early Friday. From Friday through Sunday, the system is forecast to produce 4-6 inches of rain, with localized higher amounts up to 8 inches, across southern Baja California. For northwest coastal Sinaloa, the system may produce between 6-8 inches of rain with localized higher amounts up to 12 inches. This heavy rainfall will bring a risk of flash flooding and mudslides to portions of the area. WIND: Tropical storm conditions are expected to first reach the coast of the southern Baja California Peninsula within the warning area by early Friday, making outside preparations difficult or dangerous. Tropical storm conditions are possible within the watch area by late Friday night or early Saturday. SURF: Swells generated by Tropical Depression Nine-E will affect portions of the coast of west-central Mexico during the next day or so, and will spread northward along the coasts of the southern Baja California Peninsula and mainland Mexico beginning tonight. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
