Flood Watch Issued for Kauai County and Oahu Through Thursday

Honolulu, HI, October 7, 2026 — A flood watch has been issued for Kauai County and Oahu, signaling the potential for heavy rainfall and subsequent flooding. The watch is currently in effect and is expected to continue through Thursday. Residents and authorities are advised to monitor weather updates and be prepared for potential impacts.

The National Weather Service has activated a flood watch for two of Hawaii’s major counties: Kauai County and Oahu. This alert indicates that conditions are favorable for flash flooding to occur. The watch period extends until Thursday, meaning there is a heightened risk of significant rainfall over the next several days.

Flood watches are issued when weather conditions suggest that flooding is possible. While not a guarantee that flooding will happen, they serve as an important alert for communities to be vigilant. Heavy rainfall can lead to dangerous situations, including rapid rises in streams and rivers, overwhelmed drainage systems, and hazardous driving conditions due to standing water on roadways.

Authorities are urging the public in affected areas to take necessary precautions. This may include securing loose outdoor items, preparing emergency kits, and having a plan in place should evacuation become necessary. Information regarding specific advisories and safety recommendations will be provided by local emergency management agencies as the situation develops.

The duration of the flood watch through Thursday indicates a sustained period of potential heavy precipitation. Further updates will be released by the National Weather Service and local officials as more precise weather forecasts become available and conditions change.
