MIAMI -- Forecasters say Hurricane Fabio is strengthening in the Pacific but poses no threats to land.

Fabio is still a Category 1 hurricane and is the season's fifth hurricane. Some additional strengthening is expected over the next day or so before it starts to weaken.

Meanwhile, Tropical Storm Emilia, farther out in the Pacific, is moving westward and is expected to become a remnant on Sunday.

Once a hurricane, Emilia now has maximum sustained winds of 50 mph (80 kph) and is 1320 miles (2124 kilometres) west-southwest of the southern tip of Mexico's Baja California. It is moving west at 15 mph (24 kph).
