Hurricane Genevieve briefly reached Category 5 status in the East Pacific on Monday, becoming the first storm of that intensity in the region in two years, according to the National Hurricane Center.
The system is expected to move roughly parallel to the Mexican coastline while staying far out at sea.

Data from the Miami-based center showed Genevieve had maximum sustained winds of 145 mph (230 kph).
The storm's center was located about 505 miles (810 kilometers) southwest of Baja California's southern tip, moving northwest at 12 mph (19 kph).
No coastal watches or warnings were issued, but the hurricane center warned that swells from Genevieve were creating life-threatening surf and rip currents along parts of southwestern Mexico and the Baja California peninsula.
Forecasters expect the hurricane to fluctuate in strength before weakening later in the week.
