Emilia strengthened into a Category-4 hurricane Tuesday with winds of 225 kilometers per hour (kph) as it spun in the Pacific Ocean. Tuesday morning, Emilia was about 1,100 kilometers south-southwest of the southern tip of Mexico's Baja California Peninsula, the Miami-based National Hurricane Center (NHC) said. It was moving west-northwest at about 19 kph. The storm is not expected to threaten land. While Emilia's intensity could fluctuate Tuesday, "gradual weakening is expected to begin by tonight and continue through Thursday," the NHC said. Farther west in the Pacific, the cyclone known as Daniel weakened from a hurricane into a tropical storm. Early Tuesday, Daniel's maximum sustained winds had fallen to 113 kph, under the 119-kph threshold to qualify as a hurricane, the NHC said. "Gradual weakening is forecast during the next 48 hours, and Daniel could become a tropical depression by Thursday," the weather agency said.
