Boston ? Heavy rain and dangerous rip currents from a weak tropical system emptied East Coast beaches for a second straight late-summer weekend, while a hurricane that could clip Mexico’s coast next week grew stronger in the Pacific.

Jimena, the 10th named storm of the Pacific season, quickly became a Category 2 storm with maximum sustained winds of 105 mph.

Fueled by warm Pacific waters, Jimena could be a major Category 3 hurricane by today as it tracked north-northwest at 12 mph about 580 miles off the southern tip of Mexico’s Baja California peninsula late Saturday. It was 225 miles south of Manzanillo, Mexico.

The National Hurricane Center’s five-day forecast predicts the storm’s center could pass offshore of the peninsula next week but come close enough to bring strong winds and churn up rough seas.
