Both Taiwan and Southern Japan have had extreme amounts of rainfall contributed by tropical cyclones during the past week. Tropical storm Talim weakened to a tropical depression on June 18, 2012 after passing over the northern tip of Taiwan. Flooding, landslides and at least one death in Taiwan were reportedly caused by Talim. The weakening tropical depression is now affecting Japan in areas that were just drenched by Typhoon Guchol's passage.

This image shows rainfall from data collected with two TRMM satellite orbits as it passed over that area. TRMM passed over on June 20, 2012 at 2308 UTC and then on June 21, 2012 at 0044 UTC. TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments show that rainfall was occurring in areas of the East China Sea from southern Taiwan to southern Japan. Part of the rainfall is from a frontal system. TRMM shows that a band of rainfall associated with tropical depression Talim was dropping moderate to heavy rainfall west of Okinawa. Even heavier rain, not all associated with Talim, is shown by TRMM extending from northeast of Talim to the main islands of Japan.
