HAZARDOUS SEAS WARNING IN EFFECT UNTIL 5 PM CHST MONDAY... ...TYPHOON WARNING IS CANCELLED

- Guam and Rota Coastal Waters.
- When
- Until 5 PM ChST Monday.
- Impacts
- Very steep and hazardous seas could capsize or cause damage to vessels.
- Additional details
- Typhoon and tropical storm conditions are no longer expected as Typhoon Champi continues moving away from the region. However, combined seas will be very steep due to remnant storm-induced swells and elevated wind waves. As Champi continues moving away at a relatively quick speed, seas could drop below 15 feet after midnight.
What to do
A hazardous seas warning means hazardous sea conditions are imminent or occurring. Recreational boaters should remain in port...or take shelter until waves subside. Commercial vessels should prepare for rough seas and consider remaining in port or taking shelter in port until hazardous seas subside.
