.Discussion...
0.05 inches of rain fell at Guam International Airport yesterday.
The KBDI has increased slightly to 300, which is at the very bottom of
the moderate fire danger category. In the short term, the potential
for heavy rainfall is increasing as a stationary front inches closer.
However, the potential for showers will continue today and then
fluctuate as the stationary front descends into the region. Breezy
conditions are possible with the stationary front late this weekend
into early next week.
