Flash flooding is either ongoing or expected to begin shortly, posing risks to streams, urban areas, highways, streets, and other low-lying regions with poor drainage. Flood-prone roads may be closed due to runoff and overflowing streams, and urban areas could experience significant flooding and property damage. Motorists are advised to avoid flooded roads, as most flood-related fatalities occur in vehicles. Residents and visitors are urged to stay away from streams, drainage ditches, and other flood-prone areas. (Source: Honolulu Star-Advertiser, published 2026-10-08 16:00:00 GMT)
