...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH THIS EVENING...

The Flash Flood Watch continues for

* A portion 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.

* Through this evening

* Abundant moisture will bring scattered to numerous showers and
  thunderstorms to portions of Puerto Rico today. Soils are
  already saturated, and many rivers continue to run above normal.
  Any additional heavy rainfall may lead to urban and small
  stream and/or flash flooding.

* There is a high risk of river and small stream flooding as
  well as mudslides and rockfall in areas of steep terrain both
  in rural and urban areas. Urban flooding is also likely across
  low lying and poor drainage areas. Any additional rainfall
  across these areas can lead to flash flooding.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should Flash Flood Warnings be issued.
