Octave was about 85 miles (137 kilometers) southwest of Cabo San Lazaro, Mexico, with maximum sustained winds of 50 miles per hour, the center said in an advisory at 5 p.m. New York time. It was moving north-northeast at 9 mph.
“Additional weakening is forecast during the next 48 hours and Octave could become a tropical depression on Tuesday by the time it nears the Baja California Peninsula,” the Miami-based hurricane center said.
Tropical storm warnings, meaning winds of at least 39 mph, heavy rains and surf are expected within 24 hours, were posted from Santa Fe to Punta Abreojos in Mexico. As much as 3 to 6 inches (8 to 15 centimeters) of rain may fall, with some areas getting as much as 8 inches, according to the center.
“The primary threat from Octave will be heavy rainfall that could lead to flash floods and mudslides, especially in mountainous terrain,” Stacy Stewart, a senior hurricane specialist at the center, said in a forecast analysis.
The center is also tracking Tropical Storm Priscilla, which has top winds of 45 mph and is 630 miles southwest of the southern tip of Baja California. Priscilla is moving north and isn’t a threat to land.
