Storms & Typhoons
Guam's storm season lasts from July 1 - December 31. A catastrophic typhoon has not hit the island since Pongsona in 2002, but it and other memorable storms have taught folks on Guam the importance of being prepared.
During a typhoon:
- If you are in a low-lying area or if the building you are staying in is not a concrete structure or lacks storm shutters, consider seeking shelter elsewhere.
- Stay inside and away from windows.
- If possible, stay tuned to a radio or television for storm bulletins.
- Stay inside when the eye of the typhoon is passing and prepare for heavy winds from the opposite direction.
- Fill in holes around doors with old towels or blankets.
- Turn of and unplug all appliances.
- NOAA Weather Radio broadcasts National Weather Service warnings and other hazard information 24 hours a day. Weather radios are for sale at electronics stores on Guam and via mail-order catalogues and various other locations.
