Typhoon In-fa is the equivalent of a Category 2 hurricane in the western Pacific Ocean and may affect Iwo Jima as a tropical storm later this week.
Here are the latest statistics, forecast path and satellite imagery on In-fa.

• Location: About 864 miles southwest of Iwo Jima.
• Movement: Generally toward the northwest through Monday. In-fa should then round the western edge of the subtropical ridge of high pressure and become caught up in the jet stream, bending it sharply northeast, away from Taiwan and mainland Japan this week. In-fa could bring some rain and wind impacts as it moves near Iwo Jima as a tropical storm or tropical depression Thursday into Friday. Iwo Jima has a Japanese military presence, but no permanent population. The populated Ogasawara Islands of Japan could also see some rain and wind impacts from In-fa during that time period.
• Intensity: Increasing wind shear in the week ahead should result in an increase in the weakening trend as it turns to the northeast, whisked away by the jet stream.
• Guam impacts: In-fa's center tracked more than 150 miles south of Guam with its closest pass. Andersen Air Force Base reported a couple of wind gusts from 40-45 mph Saturday. Rainfall amounts from the outer rainbands were generally 1.5 to 2 inches at both Andersen AFB and Guam International Airport.
• Adding to the record: According to Colorado State University tropical expert, Phil Klotzbach, In-fa became the 24th Cat. 4-5 tropical cyclone in the Northern Hemisphere this season, adding to the absolute pummeling of the previous record of 18 such storms in 1997 and 2004. In-fa has since weakened back to Category 2 intensity.
