Guam can expect:
-
Severe tropical storm force conditions to persist across Guam as rain bands continue to train over the island bringing heavy showers and wind gusts up to 70 mph. Those severe tropical storm force winds will gradually subside through daybreak but damaging tropical storm force winds of 39 mph or more will continue through midday. Such winds will continue to pose risk to public safety, infrastructure and power lines.
-
Residents and visitors to remain in a safe shelter until the Governor declares COR 4.
-
Peak conditions with sustained winds of 40 to 60 mph and gusts of 70 to 85 mph decreasing through the morning, eventually falling to between 20 and 30 mph by this afternoon.

Tropical storm force winds of 39 mph or more are expected to continue until Wednesday afternoon.
-
Stay out of the water; conditions are life threatening. Dangerous sea conditions are expected to last until the end of the week.
