Less than one week after Typhoon Khanun charted a zigzagging course toward southern Japan, the country was preparing for yet another major storm—Typhoon Lan.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired the image at 1:30 p.m. local time (04:30 Universal Time) on August 14, 2023. Around that time, winds were sustained at about 160 kilometers (100 miles) per hour—the equivalent of a category-2 storm on the Saffir-Simpson wind scale.
The storm made landfall over Japan on August 15, 2023, and then moved north toward the cities of Osaka and Kyoto. In addition to heavy rain and high winds, the Japan Meteorological Agency warned of floods, storm surge, and landslides. Airlines and railways cancelled services ahead of the storm.
By the evening of August 15, Lan had weakened to a tropical storm as it neared the Sea of Japan. Rainfall from the slow-moving storm caused rivers to overflow, and strong winds left thousands of homes without power.
