Hurricane Karina strengthened rapidly in the Pacific Ocean, reaching Category 4 status with maximum sustained winds of 145 mph while positioned about 1,020 miles west-southwest of Mexico's Baja California peninsula. The storm poses no immediate threat to land but is being closely monitored by forecasters. Karina initially became a hurricane on Sunday, well away from land, and forecasters expect it could become a major storm as it continues to intensify over open Pacific waters.
