017 FNMY50 PGUM 261745 FWFGUM 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.
