...FLOOD WATCH REMAINS IN EFFECT THROUGH SUNDAY AFTERNOON...

* WHAT...Flooding caused by excessive rainfall continues to be
  possible.

* WHERE...Portions of Puerto Rico, including the following areas,
  Central Interior, Culebra, Eastern Interior, Mayaguez and
  Vicinity, North Central, Northeast, Northwest, Ponce and Vicinity,
  San Juan and Vicinity, Southeast, Southwest, Vieques and Western
  Interior and Virgin Islands, including the following areas, St
  Croix and St.Thomas...St. John...and Adjacent Islands.

* WHEN...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. Low-water crossings may be
  flooded.

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

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

    Since 8 AM AST, estimated-rainfall totals around 3-5 inches
    have been observed in and around Utuado, Ponce, Catano, and
    Fajardo in Puerto Rico, and 2-4 inches in Saint Croix, US
    Virgin Islands. Additional 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 event-total 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.
