FIRE WEATHER PLANNING FORECAST FOR GUAM
NATIONAL WEATHER SERVICE TIYAN GU
417 AM CHST SUN FEB 22 2026
DISCUSSION
NO RAIN FELL AT GUAM INTERNATIONAL AIRPORT YESTERDAY ALLOWING THE
KBDI TO INCREASE TO 255, WHICH REMAINS IN THE LOW FIRE DANGER
CATEGORY. A SEASONALLY DRY TRADE-WIND PATTERN IS INTERRUPTED AS A
SOUTHWARD-MOVING SHEAR LINE PUSHES ACROSS THE MARIANAS, BRINGING
PERIODS OF SCATTERED TO NUMEROUS SHOWERS OVER THE NEXT FEW DAYS.
THIS WILL KEEP THE FIRE DANGER LOW AS THE KBDI WILL BE SLOW TO
RISE, LIKELY DECREASING IF WETTING RAINS ARE ACHIEVED.
