Fire Weather Planning Forecast for Guam
National Weather Service Tiyan GU
345 AM ChST Sun Apr 27 2025

.Discussion...
0.16 inches of rain fell at the Guam International Airport yesterday
evening as a weak trough moved through, and there has been no
wetting rainfall of 0.20 inches or greater within the last week. This
allowed the KBDI to continue increasing with today`s reading at 685,
which is in the high category. Gentle to moderate trade winds will
continue with occasional fresh gusts in the afternoon, and are
expected to remain below critical Red Flag criteria. However, fire
danger remains elevated, especially at higher terrain where stronger
winds are expected. Afternoon relative humidity values will continue
to fall near or below 60 percent. A wetting rain is not expected in
the next few days and the KBDI will likely continue to climb.
