DISCUSSION
0.01 INCHES OF RAIN FELL AT GUAM INTERNATIONAL AIRPORT YESTERDAY
ALLOWING THE KBDI TO INCREASE TO 236, WHICH REMAINS IN THE LOW
FIRE DANGER CATEGORY. A SEASONALLY DRY TRADE-WIND PATTERN CONTINUES,
HOWEVER SHEAR LINE FRAGMENTS AND PASSING TRADE-WIND TROUGHS WILL
BRING BRIEF PERIODS OF SCATTERED SHOWERS OVER THE NEXT FEW DAYS.
THIS WILL KEEP THE FIRE DANGER LOW AS THE KBDI WILL BE SLOW TO
RISE AND POTENTIALLY DECREASING IF A WETTING RAIN IS ACHIEVED
NEXT WEEK.
