The National Weather Service in Honolulu has issued a Flash Flood Emergency for Hawaii County, effective from 9:53 PM HST on August 15 through 1:00 AM HST on August 16. This is the highest alert level for flooding and means dangerous water is already occurring or imminent in affected areas.
Flash floods develop quickly—sometimes in minutes—when heavy rainfall overwhelms local drainage systems. In Hawaii’s terrain, water can rush down slopes and through valleys with little warning. Residents in the emergency zone should treat this alert seriously and take immediate protective action.
What You Might Notice
If you’re in the affected area, watch for rapidly rising water in normally dry washes, streams, and roadways. Road conditions may deteriorate suddenly, and visibility may drop due to heavy rain. Never attempt to drive or walk through flooded areas—moving water as shallow as 6 inches can sweep away vehicles, and 12 inches can carry away most people.
Who Is Affected: Residents and visitors in Hawaii County should monitor this emergency closely. If you live or are staying in low-lying areas, near streams, or in flood-prone zones, be especially vigilant.
What to Do Right Now
1. Know Your Evacuation Route—If local authorities issue evacuation orders, leave immediately. Don’t wait for a second warning. Have your vehicle fueled and important documents packed.
2. Monitor Official Updates—Follow NWS Honolulu and your county emergency management for the latest information. Sign up for emergency alerts if you haven’t already.
3. Avoid Flooded Areas—This cannot be overstated. Turn around if you encounter water on roadways. Most flood deaths involve vehicles attempting to cross rising water.
