Rescuers including elite Thai navy divers, a U.S. military team and British cave experts have been frustrated by incessant rain that has flooded the cave and made locating the boys more difficult. Despite efforts to drain the water, muddy floodwaters reached near the entrance of the cave while rescuers kept trying to find hidden shafts in the green mountainside to access the cavern. In a desperate move, officials dropped into the shafts care packages stuffed with food, beverages, a phone, a flashlight, candles, a lighter and a map of the cave.
