...FLOOD WATCH REMAINS IN EFFECT THROUGH LATE WEDNESDAY NIGHT...

* WHAT...Flash flooding caused by excessive rainfall continues to be
  possible.

* WHERE...Guam and Rota.

* WHEN...Through late Wednesday night.

* IMPACTS...Excessive runoff may result in flooding of rivers,
  creeks, streams, and other low-lying and flood-prone locations.
  Flooding may occur in poor drainage and urban areas. Low-water
  crossings may be flooded.

* ADDITIONAL DETAILS...
  - A generally unsettled pattern caused by nearby tropical
    disturbance Invest 96W embedded within an east-west oriented
    trough, is likely to produce heavy showers and thunderstorms
    to bring localized flash flooding risk to the region for at
    least the next few days. Rainfall potential of 3 to 5 inches
    is possible over Guam and Rota over the next 48 hours. This
    feature is expected to exit the region before the weekend, to
    then intensify in the open waters of the Philippine Sea as it
    heads towards Luzon during the weekend.
