What happened
The National Weather Service issued flood watches for Kauai County and Oahu, effective from the evening of October 7 through Thursday afternoon. Forecasters warned that a low-pressure area north of the Hawaiian Islands is drawing deep tropical moisture, creating a threat of heavy rain over the islands. Heavy showers could train, repeatedly moving over the same areas.

Why it matters
The warnings indicate that flood-prone roads and low-lying areas may close due to elevated runoff and overflowing streams. Urban areas are also warned that rapid runoff could lead to significant flooding and property damage.
