HONOLULU—Honolulu officials said a dam holding 21 million gallons (80 million liters) of water was not in danger of collapsing Sept. 13, but still warned nearly 10,000 residents downstream that they might need to evacuate after a tropical storm caused water levels to rise in the reservoir.
Water levels in the dam rose 4-to-5 feet (nearly 1.5 meters) overnight as heavy rains from Tropical Storm Olivia dumped 7.3 inches (18 centimeters) of rain in the area. Meteorologists downgraded the storm to a tropical depression as it moved away from the islands, but warned lingering moisture could bring more rain.
