...FLASH FLOOD WARNING WILL EXPIRE AT 715 AM CHST THIS MORNING FOR
GUAM...

Heavy showers and thunderstorms have pushed to the northwest of Guam
and stream gauges show that water levels are receding. Preliminary
rain gauge observations show 2 to 4 inches of rain fell across the
island since midnight. While no additional flash flooding is
expected in the next hour or so, waters will be slow to recede in
some areas. More showers are coming in upstream, so watch for any
Flood Advisory issuances later this morning. Please continue to
exercise caution while driving, and heed any road closures.

A Flood Watch remains in effect until 600 AM ChST Thursday for Guam
