Fire Weather Planning Forecast for Guam

National Weather Service Tiyan GU

258 AM ChST Sun Mar 1 2026



.Discussion...

0.25 inches of rain fell at Guam International Airport yesterday, 

allowing the KBDI to slightly increase to 248, which remains in 

the low fire danger category. Another round of moderate to heavy 

showers overnight presents another chance for a wetting rain

today, which may cause the KBDI to decrease a bit. The weather

pattern looks to settle down for the start of the workweek, then a

wetter pattern looks to take shape late week.
