Navigating Tropical Storm Moke in Hawaii: Safety, Impact, and Emergency Preparedness

Preparing for Tropical Storm Moke in Hawaii

Tropical Storm Moke has emerged in the Central Pacific, posing a direct flooding and wind threat to the Hawaiian Islands. Coming on the heels of severe weather systems like Hurricane Lala, Moke introduces compound hazards to already saturated terrain, particularly on the windward side of the Big Island and eastern Maui.

Navigating tropical hazards in Hawaii requires an understanding of localized weather patterns, terrain risks, and primary emergency resources. This guide details storm expectations, safety protocols, and key response contacts.

Storm Path and Expected Impacts

While the center of Tropical Storm Moke is forecast to track south of the primary island chain, tropical systems in the Pacific impact areas far beyond their central core.
The Weather Network

Torrential Rainfall & Flash Flooding: Saturated soils from previous storms mean additional rainfall of 5 to 10 inches—with localized totals up to 15 inches—can trigger rapid flash flooding and mudslides.

High Winds & Gusts: High-elevation areas and mountain passes face elevated wind hazards capable of bringing down trees and power lines.

Dangerous Surf: Rough ocean swells and rip currents create hazardous conditions along windward and southern coastlines.

Real-World Case Study: Managing Compound Flooding

In steep topography like the Hamakua Coast or Hilo district, saturated soil cannot absorb heavy rainfall. During sequential storm events, runoff rushes down gulches, turning minor streams into swift rivers within minutes. Neighborhoods downstream face road washouts and isolated conditions even if total wind damage remains minimal.

Pre-positioning supplies and monitoring stream gauges before outer rainbands arrive is essential for residents in steep or low-lying zones.

Essential Action Steps for Residents and Travelers

Secure Outdoor Belongings: Move patio furniture, trash bins, and loose equipment indoors to prevent wind displacement.

Prepare Emergency Supplies: Maintain a 14-day supply of non-perishable food, fresh water (1 gallon per person per day), medicines, and battery-powered lighting.

Avoid Driving Through Floodwaters: Never attempt to drive across flooded roads or flowing gulches.

Stay Out of the Water: Avoid beach activities, swimming, and surfing due to dangerous ocean swells and hazardous runoff.
