Andersen AFB and Naval Base Guam are both equipped with a public alert system (AKA Giant Voice) that announces the Tropical Cyclone Condition or Readiness (TCCOR). Due to Guam being located inside Typhoon Alley, both bases are always in TCCOR 4 which is weather expected within 72 hours.

The 36 CES Readiness and Emergency Management Flight always has the most current information with regard to typhoon preparedness. They can be reached at 671-366-3113.

A typhoon is a large-scale tropical storm that occurs west of the International Date Line. It would be called a hurricane if it was east of the International Date Line. A typhoon has sustained wind speeds of at least 74 mph. The warm waters surrounding Guam are ideal for the development of typhoons year round. Most occur June – December but one can occur anytime.

Tropical Cyclone Condition of Readiness (TCCOR)

• TCCOR 4: Winds of 58 mph or greater are expected within 72 hours.

• TCCOR 3: Winds of 58 mph or greater are expected within 48 hours.

• TCCOR 2: Winds of 58 mph or greater are expected within 24 hours.

• TCCOR 1 Caution: Winds of 58 mph or greater are expected within 12 hours.

• TCCOR 1 Emergency: Declared when sustained destructive winds reach or exceed 58 mph.

• TCCOR 1 Recovery: Declared when destructive winds have passed, but dangerous weather may still exist.

Little to no movement should take place on base TCCOR 3, 2, or 1. The base traffic signs (stop signs, speed limit signs, etc.) are removed during TCCOR 3, so proceed with caution at all intersections.

Typhoon Preparedness Kit should include enough supplies for at least 1-2 weeks.

Contents should include: canned & ready-to-eat food, can opener, 1-2 gal water per person per day, propane stove, first aid kit, plastic dining ware, flashlight/batteries, cash, mop/towels, duct tape, hygiene items, baby supplies (formula, diapers, etc.), battery-operated radio, 550 cord/rope, medications, and tool kit.

Housing Residents and Member Responsibilities

Please refer to your base’s housing guide for detailed information regarding typhoon preparedness.

Earthquakes

If inside...

1.         Drop to the floor.

2.         Take cover under a sturdy desk or furniture and be prepared to move with it. Hold this position until ground stops shaking and it is safe to move.

3.         Stay clear of windows, fireplaces and heavy furniture or appliances.

4.         Stay inside.

5.         Stay calm.

If outside...

1.         Get into the open and away from buildings and power lines.

2.         If driving, stop if you are in a safe location; however, stay inside your car.

3.         Stay away from bridges, overpasses, and tunnels.

4.         If possible, avoid stopping under trees, light posts, power lines, or signs.

5.         If near mountainous area or unstable cliffs, be alert for falling rock and other debris.

6.         If at the beach, move to higher ground.

Tsunamis

Tsunamis are a series of large ocean waves generated by large undersea disturbances, such as a major earthquake or landslide. Tsunamis are not affected by tides or currents. A tsunami means the whole water column is moving, not just the surface. Tsunamis can strike any ocean shoreline. If you are on the beach or in low coastal areas, you may not have much time to seek higher ground. The tsunami danger period can last several hours as the waves move onto land, recede, and return. The second and third waves have been known to be more devastating than the first.

Be aware of the signs

1.         A strong earthquake lasting 20 seconds or more near the coast.

2.         A noticeable rapid rise or fall in coastal waters.

3.         A loud roaring noise from the ocean. If you suspect a potential tsunami, move to your designated assembly area or proceed inland and uphill.

What to do during watch

1.         Use a NOAA Weather Radio or listen to local radio or television stations for updated information.

2.         Locate loved ones and review evacuation plans. Be ready to move quickly if a tsunami warning is issued.

3.         Tsunamis produce strong currents or waves dangerous to those in or near the water. Local officials may close beaches, evacuate harbors and marinas, and ask ships to reposition to deep water. Obey their directions.

What to do during warning

1.         If you hear a tsunami warning siren or suspect a tsunami at your location, leave the area immediately.

2.         Offer assistance to those who may need help evacuating the area.

3.         Bring pets with you to keep them safe.

4.         Take your disaster supply kit.

5.         Move to higher ground as far inland as possible.

6.         Keep listening to the NOAA Weather Radio, local radio, or TV for the latest updates.

What to do after tsunami

1.         Return home only after local officials tell you it is safe.

2. Stay away from damaged areas so emergency responders can have full access.

3.         Stay out of any building that has water around it.

4.        Be careful re-entering buildings or homes. Tsunami-driven floodwater may have damaged buildings.

Ridin’ the storm out with Dave
