Tropical Storm Ivo trudges north-northwest off Baja coast [UPDATE] MIAMI, Aug. 24 (UPI) -- Tropical Storm Ivo was little changed Saturday as it churned off Mexico's Baja California peninsula, producing heavy rains and strong winds, forecasters said. In its 2 a.m. advisory, the National Hurricane Center in Miami said Ivo was about 180 miles west of Cabo San Lucas, Mexico, heading to the north-northwest at 14 mph. Ivo had maximum sustained winds of 45 mph and was forecast to move parallel to the peninsula's west coast for the next couple of days. The center said there was a tropical storm warning in effect for the Pacific coast of the peninsula from Punta Abreojos southward to Cabo San Lucas, and along the Gulf of California coast of the peninsula from Loreto south to Cabo San Lucas. Ivo could strengthen slightly during the next 12-18 hours but was expected to begin weakening Saturday night. Ivo covers a large area, with tropical storm force winds extending as far as 195 miles from its center. The storm is expected to produce 1-3 inches of rain in general, with a possible 5 inches in some areas of the peninsula.
