Issued By

Honolulu - HI, US, National Weather Service

Affected Area

Oahu

Description

WHAT...Flash flooding caused by excessive rainfall is possible. WHERE...Oahu. WHEN...Through late tonight. IMPACTS...Significant flooding may occur due to the overflow of streams and drainages. Roads in several areas may be closed, along with property damage in urban or low lying spots due to runoff. Landslides may also occur in areas with steep terrain. ADDITIONAL DETAILS... - Considerable flash flooding remains possible as a large and powerful kona storm northwest of the state draws deep tropical moisture northward across the islands. Persistent bands of heavy rain and thunderstorms may produce intense rainfall rates, leading to rapid rises in streams and flooding of roads and low lying areas. PRECAUTIONARY/PREPAREDNESS ACTIONS... You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
