🌧️⚠️ BIG ISLAND WEATHER ALERT: MONSOON TROUGH HEADING TOWARD HAWAIʻI! 🌩️🌊
A potentially significant weather system is developing near the Hawaiian Islands, bringing the threat of heavy tropical rainfall, thunderstorms, and dangerous flash flooding to the Big Island.
📅 WHEN? October 25–29, 2026
⚡ WHAT’S HAPPENING?
A monsoon trough is a large area of low pressure that draws warm, moisture-rich tropical air toward Hawaiʻi. As that moisture moves over our islands and mountains, it can produce intense rainfall and thunderstorms.
🚨 WHAT BIG ISLAND RESIDENTS SHOULD KNOW:
🌧️ Heavy rainfall and localized flooding possible
⚡ Thunderstorms and intense downpours
🌊 Flash flooding in low-lying areas
🌳 Falling trees, debris, and possible power outages
🚧 Flooded roads and dangerous driving conditions
📍 Hilo, Puna, Hāmākua, Kona, and surrounding communities should stay weather-aware. Impacts will vary by location.
⚠️ Tuesday and Wednesday, October 27–28, are currently a key period to watch. Forecast timing and severity may change.
🏡 PREPARE NOW, NOT DURING THE STORM!
✔️ Secure tents, canopies, and outdoor belongings
✔️ Clear gutters and drainage areas
✔️ Charge phones and backup batteries
✔️ Prepare emergency supplies
✔️ NEVER drive through flooded roadways
🌺 This is NOT a hurricane warning. The primary concern is potentially excessive rainfall and flooding.
