Tropical Storm Lala brings heavy rain, flooding threat to Oahu

HONOLULU (HawaiiNewsNow) – Tropical Storm Lala is impacting Oahu Sunday morning, bringing heavy rain, strong winds and dangerous flooding conditions across the island.

Lala weakened from a hurricane to a tropical storm as it continued moving west through the island chain, but officials warn hazardous conditions remain.

Heavy rain has already prompted flash flood warnings across Oahu, with flooding reported in several areas.

Residents are being urged to stay off the roads when possible, avoid flooded areas and stay away from streams and other waterways as conditions continue to change.

Flooding and heavy rain

The National Weather Service warned of life-threatening flash flooding Sunday morning as bands of heavy rain moved across Oahu.

A Flash Flood Warning is in effect until 9 a.m. as bands of heavy rain continue moving over Oahu.

As of 5:18 a.m., the National Weather Service said rain was falling at rates of 1 to 3 inches per hour, with additional heavy rain expected over the next several hours.

Forecasters said Manoa Stream was showing record streamflow and was likely causing considerable impacts.

The warning includes Honolulu, Waipio, Pearl City, Mililani, Waikele, Aiea, Wahiawa, Waipahu, Wheeler Field, Kunia, Halawa and Waiahole.

Forecasters said streams were rising rapidly in some areas, while flooding could impact roads, highways, underpasses and low-lying communities.

Traffic alerts and road closures

High winds and heavy rain have triggered multiple road closures, and residents are urged to stay off the roads. New closures have been reported on scenic routes:

HPD asks to avoid these areas if possible, but if you must travel, find alternate routes and please drive with caution and give as much space for responders to work safely and efficiently.
