Red notification for tropical cyclone SINLAKU-26. Population affected by Category 1 (120 km/h) wind speeds or higher is 52601 .

Summary

From April 9-16, 2026, Typhoon SINLAKU-26 is striking the Northern Mariana Islands and Guam region. This powerful typhoon with maximum wind speeds of 287km/h has exposed 52,601 residents to Category 1 or higher winds (120km/h+), with severe supply-chain disruption risks anticipated.

Supply-chain impact

• Suspension of Guam-Saipan air routes will inevitably disrupt Asia-North America air cargo transport and passenger connections
• Shutdown of Guam Naval Base and Andersen Air Force Base operations would impact Western Pacific military logistics supply chains
• Closure of local port facilities (Apra Harbor, Saipan Commercial Port) will delay supply of essential materials including construction materials, fuel, and food
• Given the tourism-centered economic structure, damage to hotels and resort facilities will drive urgent demand surge for reconstruction materials and equipment
• Communication infrastructure damage could temporarily paralyze US mainland-Asia submarine cable relay functions

Watch points

• Need to track reopening timeline of Guam International Airport and Saipan International Airport and flight normalization schedule
• Operational resumption of Andersen Air Force Base and Apra Naval Base serves as key indicator for Western Pacific military logistics normalization
• Essential to monitor local power grid recovery status and port cargo handling equipment restart timing after typhoon passage
