...FLOOD WATCH IN EFFECT FROM FRIDAY MORNING THROUGH SUNDAY
AFTERNOON...

* WHAT...Flooding caused by excessive rainfall is possible.

* WHERE...Puerto Rico and the U.S. Virgin Islands.

* WHEN...From Friday morning through Sunday afternoon.

* IMPACTS...Excessive runoff may result in flooding of rivers,
  creeks, streams, and other low-lying and flood-prone locations.
  Creeks and streams may rise out of their banks. Flooding may occur
  in poor drainage and urban areas.

* ADDITIONAL DETAILS...
  - A trough combined with deep moisture across the local area
    will bring periods of showers and thunderstorms across the
    local islands during the next several days, particularly
    Friday through at least Sunday.

    Based on the latest guidance, the most likely time period for
    the heaviest rainfall activity is Friday afternoon into
    Saturday. The areas most likely to receive the highest
    rainfall accumulations are portions of the southeast and east
    sections of Puerto Rico, as well as Vieques, Culebra and the
    US Virgin Islands.

    Rainfall accumulations are expected to range from 2 to 4
    inches, especially for the eastern half of Puerto Rico and
    the Virgin Islands with isolated higher amounts possible
    between 6 and 8 inches. Elsewhere, 1 to 3 inches are
    expected.

    Due to already saturated soils, any prolonged period of heavy
    rainfall will result in urban and small stream flooding. Some
    rivers will likely overflow their banks. Therefore, Isolated
    life threatening flash flooding and mudslides are possible as
    well.
