...FLASH FLOOD WATCH NOW IN EFFECT THROUGH SATURDAY MORNING...

The Flash Flood Watch is now in effect for

* A portion of Puerto Rico, including the following areas,
  Central Interior, Eastern Interior, Mayaguez and Vicinity,
  North Central, Northeast, Northwest, Ponce and Vicinity, San
  Juan and Vicinity, Southeast, Southwest, and Western Interior.

* Through Saturday morning

* Deep southerly flow extends across Puerto Rico and the U.S.
  Virgin Islands in the wake of Hurricane Maria. This will
  continue to lead to heavy rainfall, especially along the
  southern slopes of Puerto Rico, St Thomas, and St John. The
  additional rainfall will allow for rapid rises along all
  streams and rivers in 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.

* Until 545 AM AST Saturday

* At 540 PM AST, satellite estimates, recent rainfall, and available
  river gauge reports indicate that continued areas of flooding
  across portions of Puerto Rico are likely through the overnight
  hours tonight. Some areas are likely to receive additional
  rainfall amounts of 1 to 2 inches over the next day or so, which
  could enhance flooding concerns.

* Some locations that will experience flooding include...
  San Juan, Ponce, Arecibo, Yauco, Fajardo, Guayama, Coamo, Jayuya,
  Adjuntas, Santa Isabel, Canovanas, Sabana Seca, San Sebastian,
  Naranjito, Humacao, Mayaguez, San German, Lajas, Hatillo and
  Penuelas.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don`t drown when encountering flooded roads. Most flood
deaths occur in vehicles. Nighttime driving is extremely dangerous.
Do not drive at night unless you are fleeing an area subject to
flooding or under an evacuation order.

In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to cross flooded
roads. Find an alternate route.
