An area of low pressure centered about 150 miles south-southeast of the southern tip of Baja California is moving north-northwestward at 10 to 15 mph and is accompanied by winds to gale force. This system lacks sufficient organized thunderstorm activity to be classified as a tropical cyclone at this time. Although upper-level winds do not appear conducive for significant development, an increase in thunderstorms would likely result in the formation of a tropical storm. Interests in southern Baja California should monitor the progress of this system as a tropical storm warning may be required for that area tonight or early Tuesday. There is a high chance, 70 percent, of this system becoming a tropical cyclone<!--more--> during the next 48 hours.
