Typhoon Matsa began forming in the northwestern Pacific off the Philippines and is gradually forming into a full fledged typhoon as the storm system travels north into the Yellow Sea.
Typhoon Matsa is shown here on the morning of August 5, 2005. This image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite at 05:15 UTC (3:15 p.m. local time). The typhoon is a well-organized, mature storm by this point, with steady winds of around 150 kilometers per hour (90 miles per hour). The high-resolution image provided above is 250 meters per pixel. The MODIS Rapid Response System provides images of Typhoon Matsa at additional resolutions.
