Typhoon In-Fa: Latest Strength, Track and Forecast
Typhoon In-Fa in the Western Pacific has 105 mph maximum sustained winds and is moving slowly south-southwest, the Joint Typhoon Warning Center says.
The latest official information comes from the Joint Typhoon Warning Center (JTWC) Warning #036, valid at 0600 UTC on 1 November, with the warning text issued at 0900 UTC.
Where the Storm Is Now
JTWC placed the center of Typhoon In-Fa near 22.3N, 144.1E at 0600 UTC, based on satellite imagery. The agency describes that spot as approximately 215 nautical miles southeast of Iwo To. A later check at 0900 UTC put the center near 22.2N, 143.8E.
The typhoon is moving slowly. Over the past six hours it tracked toward 200 degrees, or south-southwest, at about 6 mph.
Strength
JTWC reports maximum sustained winds of 105 mph, with gusts up to 125 mph. That is equivalent to a Category 2 storm on the Saffir-Simpson scale. JTWC measures sustained winds as a one-minute average.
The agency gives the minimum central pressure at 0600 UTC as 967 mb. It also estimates the maximum significant wave height near the storm at 29 feet.
Size
Over open water, JTWC says tropical-storm-force winds reach as far as 140 nautical miles from the center, with the widest reach on the northwest side.
Forecast
JTWC expects In-Fa to remain a slow mover over the next few days. Its forecast track turns gradually from west, to northwest, to north, and then sweeps to the northeast. The agency forecasts the following positions:
- 1800 UTC on 1 November (12 hours): near 22.0N, 142.9E
- 0600 UTC on 2 November (24 hours): near 22.2N, 141.2E
- 0600 UTC on 3 November (48 hours): near 23.1N, 139.5E
- 0600 UTC on 4 November (72 hours): near 24.9N, 138.9E
- 0600 UTC on 5 November (96 hours): near 28.9N, 141.6E, when JTWC says the system will be becoming extratropical
JTWC's forecast keeps the system at typhoon strength through the 96-hour point, when it is expected to be in the process of becoming extratropical. That means it would lose its tropical characteristics and take on those of a storm in the middle latitudes. The agency's outlook for 6 November places the system farther northeast, near 36.5N, 152.1E, as an extratropical storm.
Forecasts this far ahead carry real uncertainty, and the track can shift from one advisory to the next, especially for a storm that is moving this slowly.
Who Should Watch It
Anyone with interests in the waters and islands of the northwestern Pacific, including mariners in the region around Iwo To, should keep an eye on the latest warnings. Follow your local officials and your national weather service for guidance specific to your area.
What Comes Next
JTWC says its next warnings are scheduled for 1500 UTC and 2100 UTC on 1 November, and 0300 UTC and 0900 UTC on 2 November.
