(Tumon, Guam) The National Weather Service has issued a typhoon watch for the Northern Mariana Islands island of Alamagan, which is north of Saipan. A typhoon watch means that typhoon strength (destructive winds of 74 mph or more) winds are anticipated for the area where the typhoon watch is within 48 hours.

The main islands of the NMI, plus Agrihan and Anatahan, are under a tropical storm watch. This means those islands are anticipated to face damaging winds between 39 to 74 mph within 48 hours.

Guam is within Tropical Depression 20's trajectory, but on the track's southern perimeter. Earlier tonight the Joint Typhoon Warning Center placed the storm at 946 miles east of Guam, moving on a westward track at around 17 mph. The storm is expected to intensify quickly over the next 48 hours into a typhoon by the time it passes through the Marianas. It will begin to take a west-northwest turn during this time.

The JTWC is forecasting that it will become a super typhoon within 120 hours.
