...flash flood watch remains in effect through friday afternoon...

the flash flood watch continues for

* portions of puerto rico and virgin islands, including the 
  following areas, in puerto rico, 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. 
  in virgin islands, st croix and st.thomas...st. john...and 
  adjacent islands. 

* through friday afternoon

* deep southerly flow as hurricane maria continues to move away
  will continue to lead to heavy rainfall, especially along the
  southern slopes of puerto rico, and across the south sides of
  the st thomas and st john. this will lead to rapid rises along
  all streams and rivers at the u.s. virgin islands and puerto
  rico. mudslides are also expected. any homes in low-lying areas
  near rivers and streams will be flooded and flooding may leave
  residents with no avenue of escape. 

precautionary/preparedness actions...

a flash flood watch means that conditions may develop that lead
to flash flooding.
