237 FNMY50 PGUM 311713 FWFGUM Fire Weather Planning Forecast for Guam National Weather Service Tiyan GU 313 AM ChST Sun Jun 1 2025 .Discussion... 0.09 inches of rain fell yesterday at the Guam International Airport, which allowed the KBDI to fall to 714. This is in the high category due to winds remaining below the 20 mph threshold. Winds should remain below the Red Flag Warning criteria the next few days, though RHs continue to drop to around 60 percent. There will be a few chances for scattered showers the next couple of days, but a widespread wetting rain remains unlikely through the early week period. Even though Red Flag Warning criteria is not expected, the very dry conditions across the island will maintain a high fire danger.
