It is expected to move east in the next 24 hours, picking up strength to increase its average wind speed to between 75 and 100km per hour.
In the next 24 to 48 hours, Nakri will travel slowly southward before veering westward, and is expected to be located 260 kilometers northeast of Song Su Tay Island on Friday morning.
In the next 48 to 72 hours, the storm will keep traveling west and become more powerful.
As of 7:00 am on Saturday, it will be about 190 kilometers west of Song Su Tay Island, unleashing winds at 100 to 135km per hour and gusts at 160km an hour.
