HONOLULU (HawaiiNewsNow) - A Flood Advisory has been canceled for Oahu, but forecasters say there's still a threat of heavy rains.
On Tuesday, torrential rains drenched Oahu, spurring flooding and creating dangerous conditions on roadways from the urban core to Windward Oahu.
The city Department of Emergency Management was partially activated, monitoring conditions islandwide as rivers rose and roads flooded.
Manoa stream peaked at about 8 feet Monday night, double the usual height, but there were no reports of damage.
A Flash Flood Warning that had been in effect for much of Tuesday was finally allowed to expire at 8:15 p.m. The Flash Flood Watch for Oahu, Kauai and Molokai also expired.
In the most intense storms Tuesday, rain was falling at a rate of 3 to 4 inches an hour.
As of Tuesday evening, Honolulu got 2.56 inches of rain, beating a record of 2.09 inches in 1992.
The heavy rains snarled traffic in several spots, and caused a number of accidents. Several were reported to be serious.
About 9 p.m., a downed tree closed Kailua-bound lanes of the Pali Highway.
Earlier in the evening, police also closed Tantalus Drive after a tree fell on the road.
Both roadways have since reopened.
The downpours didn't even spare Waikiki, where sustained drenching rains aren't as common.
About 2 p.m. Tuesday, ponding at the Honolulu Zoo forced the city to close the attraction.
The zoo reopened Wednesday after crews cleaned up mud and debris.
And city officials closed the City Lights display at Honolulu Hale on Tuesday night due to the severe weather.
Meanwhile, firefighters responded to several calls of hikers in distress on Oahu trails Tuesday.
Five hikers were rescued from the Maunawili Trail after getting stuck by rising waters. There were no injuries reported, but fire officials used the rescue to urge hikers to stay off trails in wet weather.
The heavy rains didn't stop many from heading to shopping malls to spend gift cards or return unwanted gifts.
"It's crazy," said shopper Sydney Kushima, of Ewa Beach. "We were just talking about how we hope the weather discourages people from going to the mall because we were planning on doing a lot of returns and stuff."
The parking structures at Ala Moana Center were just as busy, with people driving a little more cautiously with the rain and flooding in some areas.
Forecasters said the severe weather is being caused by an upper trough that's enhancing the possibility for heavy showers.
