The primary risk from Tropical Storm Moke is heavy rainfall, which could lead to life-threatening flooding and mudslides, especially in areas already saturated from Hurricane Lala. The Big Island and eastern Maui are at the highest risk, with significant rainfall expected to exacerbate existing vulnerabilities. A flood watch remains in effect for parts of the Big Island through Monday afternoon. The steep terrain of the islands increases the likelihood of rapid water accumulation and landslides, posing a threat to residents and infrastructure.
