Hawaii Faces Significant Flood Threat Through Friday With 8 to 12 Inches of Rain, Flash Flooding and Landslide Risk Across Islands

HAWAII — A dangerous flooding situation is unfolding across the Hawaiian Islands, where heavy rainfall and saturated ground conditions are expected to trigger significant flash flooding through Friday.

Flash Flooding and Urban Flooding Threat Expands Across Islands

Forecast guidance indicates that considerable flash and urban flooding impacts will begin Thursday and continue through Friday, affecting multiple islands.

As heavy rainfall redevelops and spreads eastward, roads, low-lying areas, and urban locations are at high risk of rapid flooding, especially where drainage systems become overwhelmed.

Heavy Rainfall Totals Could Reach Dangerous Levels

Rainfall totals are expected to range between 8 to 12 inches, with locally higher amounts possible, particularly in areas prone to persistent downpours.

Rainfall rates may exceed 1.5 inches per hour in some locations, significantly increasing the risk of flash flooding in a short period of time.

Landslide Risk Increasing in Steep Terrain Areas

With soils already saturated from recent rainfall, additional heavy rain is likely to trigger landslides in areas of steep terrain.

This adds another layer of danger, especially in mountainous regions where unstable ground conditions can quickly worsen.

Travel Conditions May Become Hazardous

Flooding is expected to create dangerous travel conditions, particularly where roads become covered with water or debris.

Drivers are urged to remain cautious, as conditions may change rapidly. Floodwaters can rise quickly, making some routes impassable within minutes.

Flood Impacts Could Become Widespread

The combination of prolonged rainfall, saturated soils, and repeated storm activity means that flood impacts could become widespread across the islands.

In addition to roadway flooding, impacts may include water entering structures, inundation of low-lying areas, and rapid rises in streams and rivers.

What Residents Should Do Now

Residents across Hawaii should remain alert for warnings and be prepared to take action if flooding develops.

Avoid flooded roadways and consider alternate travel plans as conditions worsen. The threat will persist through Friday, making this a multi-day flooding event with increasing risks over time.
