Typhoon No. 31 (In-fa) is forecast to strengthen from 80 kt (148 km/h) to 95 kt (176 km/h) over the next three days while moving slowly across the western North Pacific, according to the Japan Meteorological Agency (JMA). The typhoon is then expected to pick up speed and turn northwest by 31 October.

FORECAST TRACK SUMMARY
Typhoon No. 31 (In-fa) is forecast to remain nearly stationary through 27 October, then move west and later northwest across the western North Pacific. Its forward speed is expected to increase through 30 October.
No grade change is forecast. Typhoon No. 31 (In-fa) is expected to remain a typhoon (TY) throughout the period. Forward speed is forecast to peak at 35 km/h (18 kt) on 30 October, when the center is expected to be in the vicinity of the Mariana Islands. The typhoon is then forecast to slow and turn northwest by 31 October. The probability circle, which is the area where JMA expects the center to remain, grows from 120 km (65 NM) to 330 km (180 NM) over the period. Track uncertainty is therefore higher in the later part of the forecast, and the position on 30–31 October could shift as new forecasts are issued.
INTENSITY FORECAST
Typhoon No. 31 (In-fa) is forecast to remain a typhoon throughout the period. JMA expects its intensity to be classified as "Very Strong" from 27 October onward.
No weakening or transition to an extratropical low is forecast within the period.
IMPACTS & THREATS
The storm warning area, where winds of 50 kt or greater are possible, is forecast to expand from a radius of 210 km (115 NM) on 27 October to 460 km (250 NM) on 31 October. Vessels operating in the western North Pacific may encounter rough seas and strong winds. Mariners should monitor the typhoon closely as it begins to move faster from 29 October.
Because the forecast track passes near the Mariana Islands on 30 October, interests in that area should follow official local warnings.
