Written by on June 21, 2021

The National Weather Service (NWS) Guam Weather Forecast Office continues to monitor what is now Tropical Depression 06W, formerly known as Joint Typhoon Warning Center Invest Area 94W.

A tropical storm warning is now in effect for Guam, meaning tropical storm conditions, including damaging winds of 39 mph or more, are expected early Tuesday morning through Tuesday afternoon.

As of 1 p.m., 06W was located 11.4 degrees north latitude and 146.9 degrees east longitude, about 200 miles southeast of Guam. It is currently moving west-northwest at 12 mph with maximum sustained winds of 35 mph.

06W is expected to maintain its intensity through tonight then slowly intensify, becoming a tropical storm Tuesday morning. At that time, low-end tropical storm force conditions are expected for Guam. Typhoon force winds are not expected.

Guam can expect sustained winds of 15 to 25 mph with gusts to 35 mph tonight, and 20 to 30 mph with gusts up to 40 possible in the stronger showers and thunderstorms Tuesday. Stronger gusts are likely across the southern coastal waters. Stronger tropical storm-force winds are expected just off the shore of Merizo and for southern Guam. The system’s closest point of approach is expected Tuesday morning.
