SITUATION OVERVIEW
------------------

Hurricane Maria was located over the waters northwest of Puerto Rico 
and moving slowly away tonight. Tropical storm force winds have 
largely ended, though occasional gusts above tropical storm force 
will be possible overnight, particularly at higher elevations. 
Rainfall amounts have ranged between 15 and 25 inches with 40 inches 
or greater in isolated spots. Catastrophic flash flooding continues 
across much of Puerto Rico with some rivers and tributaries 
exceeding record levels. Travel is strongly discouraged tonight as 
rushing flood waters continue covering many roads. Some bridges and 
roadways have likely completely washed away and it will be very 
difficult to see this at night when driving. 

POTENTIAL IMPACTS
-----------------

* FLOODING RAIN:
Additional impacts from flooding rain are still a concern. Remain 
  well guarded against life threatening flood waters having further 
  impacts of devastating potential across Puerto Rico and extensive 
  potential in the U.S. Virgin Islands.

* WIND:
Little to no additional impacts are anticipated at this time across 
Puerto Rico and the U.S. Virgin Islands.

* SURGE:
Any remaining storm surge flooding will subside overnight across 
coastal areas of Puerto Rico and the U.S. Virgin Islands.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------

* EVACUATIONS:
Do not return to evacuated areas until it is safe. Listen for the 
  all-clear signal from local authorities.

* OTHER PREPAREDNESS INFORMATION:

If your home or shelter was damaged, be alert to the smell of natural 
gas leaks and cautious around exposed electrical wiring, broken 
glass, jagged metal and wood, and protruding nails and screws.

Those who rode out the storm away from their home or business are 
likely anxious to return. However, allow some time for work crews to 
make a clear path for emergency vehicles. Downed power lines and 
trees may be blocking roads and flood waters may have washed out or 
overspread sections of key travel routes. Traffic lights may also be 
out of service.

When inspecting damage, use flashlights rather than candles or flamed 
lighting. Be aware of sparks that can ignite leaking gas or other 
flammables.

If using a generator, avoid carbon monoxide poisoning by following 
instructions by the manufacturer. Make sure that the generator is run 
in a well ventilated space.

Problems with sewer backups can further contaminate standing flood 
waters. Keep children away. Also, listen for boil water alerts 
relative to communities whose tap water may have become non-potable.

Do not wade through flood waters. Dangerous wildlife, contaminants, 
and active power lines are all potential threats.

NEXT UPDATE
-----------

As it pertains to this event...this will be the last local statement 
issued by the National Weather Service in San Juan PR regarding the
