EWWGUM The National Weather Service in Tiyan Guam has issued a * Extreme Wind Warning for... Southern Guam in Guam... * Until 530 AM ChST. * At 326 AM ChST, Andersen AFB Doppler radar indicated extreme winds, associated with the northern eyewall of Typhoon Champi, were moving onshore from Talofofo southward, moving west at 15 mph.

What the agency told people to do
Destructive winds of 115 to 135 mph will spread across far southern Guam, producing swaths of significant to catastrophic damage, particularly to non-concrete structures. TAKE COVER NOW! The safest place to be during a major typhoon passage is in a reinforced interior room away from windows. If you are not in a fully-concrete structure, get under a table or other piece of sturdy furniture. Use mattresses, blankets or pillows to cover your head and body. Remain in place through the passage of these life-threatening conditions.
