FORECAST TRACK SUMMARY
Typhoon No. 31 (In-fa) is expected to keep a steady forward speed of about 30 km/h through 31 October, then slow sharply and change direction.

The forecast shows no grade change, with Typhoon No. 31 (In-fa) remaining a typhoon throughout. On 30 October the center is forecast to pass near the northern Mariana Islands. It is then expected to turn northwest, slow almost to a stop on 1 November, and begin moving back to the west-southwest and west. The probability circle grows from 55 km (30 NM) to 220 km (120 NM), so confidence in the track drops considerably after 31 October.
INTENSITY FORECAST
Typhoon No. 31 (In-fa) is forecast to hold its current strength through 3 November.

JMA expects the "Very Strong" classification to continue, with no weakening or transition to an extratropical low in the forecast period. The expected peak is now 90 kt, down from the 95 kt (176 km/h) forecast earlier in the week.
IMPACTS & THREATS
The storm warning area, where winds of 50 kt or more are possible, is forecast to grow from a radius of 190 km (105 NM) to 400 km (215 NM) by 3 November. Vessels in the western North Pacific may encounter rough seas and strong winds. Interests in the northern Mariana Islands should follow official local warnings as the typhoon passes on 30 October.
