HONOLULU (AP) - Honolulu officials are asking residents near a dam to stay alert for the possibility of evacuating as water levels in the reservoir rise amid heavy rains.
 
City spokesman Andrew Pereira said Thursday it appears the rain is subsiding, but the city is taking a cautious approach and asking residents to remain alert.
 
The city's Board of Water Supply says 10,000 people may need to be evacuated near Nuuanu Dam No. 1.
 
The agency says it's siphoning and pumping water to keep it below the spillway.
 
Tropical Storm Olivia dumped heavy rains Wednesday on Maui and Oahu as it crossed the state.
 
Meteorologists say it's now a tropical depression moving away from the islands, but moisture will linger.
