THE NATIONAL WEATHER SERVICE IN SAN JUAN HAS ISSUED A

* FLOOD WARNING FOR URBAN AREAS AND SMALL STREAMS IN...
  BARCELONETA MUNICIPALITY IN PUERTO RICO...
  MANATI MUNICIPALITY IN PUERTO RICO...
  THIS INCLUDES THE CITY OF BARCELONETA...

* UNTIL 100 PM AST

* AT 910 AM AST... THE USGS RIVER GAGE SENSOR ON RIO GRANDE DE MANATI
CONTINUES WELL ABOVE FLOOD STAGE ALONG THE BORDER BETWEEN 
BARCELONETA AND MANATI. IN ADDITION...EMERGENCY MANAGEMENT OFFICIALS 
OF MANATI REPORTED THAT THE HIGHWAY 2 BETWEEN ARECIBO AND MANATI IS 
FLOODED AND IMPASSABLE. 

A FLOOD WARNING MEANS THAT FLOODING HAS BEEN REPORTED. STREAM RISES 
WILL BE SLOW AND FLASH FLOODING IS NOT EXPECTED. HOWEVER...ALL 
INTERESTED PARTIES SHOULD TAKE NECESSARY PRECAUTIONS IMMEDIATELY.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

MOST FLOOD DEATHS OCCUR IN AUTOMOBILES. NEVER DRIVE YOUR VEHICLE INTO
AREAS WHERE THE WATER COVERS THE ROADWAY. FLOOD WATERS ARE USUALLY
DEEPER THAN THEY APPEAR. JUST ONE FOOT OF FLOWING WATER IS POWERFUL
ENOUGH TO SWEEP VEHICLES OFF THE ROAD. WHEN ENCOUNTERING FLOODED
ROADS MAKE THE SMART CHOICE...TURN AROUND...DONT DROWN.
