...FLOOD WATCH REMAINS IN EFFECT THROUGH WEDNESDAY MORNING...

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

* WHERE...Puerto Rico, including Vieques and Culebra, and the U.S.
  Virgin Islands.

* WHEN...Through Wednesday morning.

* 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. Area creeks and streams are running high and could flood
  with more heavy rain.

* ADDITIONAL DETAILS...
  - The Flood Watch remains in effect through Wednesday morning,
    as conditions remain favorable for excessive rainfall and
    flooding across the region. Since midnight, radar-estimated
    rainfall totals have reached around 4 to 5 inches across the
    southwestern interior of Puerto Rico and portions of the
    northern U.S. Virgin Islands. Secondary maxima of 2 to 3
    inches have been observed across Vieques, Culebra, and
    portions of the southern interior and coastal plains of
    Puerto Rico.

    While the exact placement and timing of the heaviest rainfall
    has varied from earlier expectations, the overall forecast
    remains on track, with a moist and unstable pattern in place.
    Additional rainfall amounts of 1 to 3 inches per day, with
    locally higher totals, are expected to continue tonight into
    Tuesday. With soils becoming saturated and some rivers
    already running high, the risk of flooding will increase
    through at least early Wednesday morning.

Warnings. Those living in areas prone to flooding should be prepared
to take action should flooding develop.
