Tropical storm Julia turned into a hurricane on Saturday evening as it passed the Colombian island San Andres and headed toward the Caribbean coast of Nicaragua with maximum sustained winds of 75 mph (120 km/hr), the U.S. National Hurricane Center (NHC) said.
"Life-threatening flash floods and mudslides possible from heavy rains over Central America and Southern Mexico through early next week," the NHC said.
The storm is barreling toward Nicaragua "in a hurry," NHC said earlier on Saturday.
