That put In-fa about 775 miles east southeast of Agrihan, 755 miles east southeast of Pagan and 820 miles east of Guam, moving west northwest at 15 mph. A Typhoon Watch is in effect for Alamagan, Pagan and Agrihan, meaning winds of 74 mph or more are possible within 48 hours.

The Joint Typhoon Warning Center put In-fa's winds at 130 knots gusting to 160 knots in warning 21. The weather service expects the storm to hold its strength tonight and begin to weaken Friday.
