(Mexico City) -- Still reeling from destructive floods last month, Acapulco, Mexico is bracing for another onslaught from Mother Nature. Tropical Storm Raymond has become a hurricane as it made its way towards Mexico's Pacific Coast Sunday. The storm system is threatening to unload heavy rain on Acapulco. Mexico absorbed its worst flooding on record when tropical storms Manuel and Ingrid converged from Mexico's Pacific and Gulf coasts in mid-September. More than 150 people were killed and damage was estimated at about six-billion dollars.
