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

Henri has weakened to a tropical storm with tropical storm force winds
no longer expected for New Jersey land or ocean zones. However, the 
system is still expected to impact the region with heavy rain as it 
tracks north across eastern Long Island into southern New England. 

The main threat with this system is heavy rain leading to flash
flooding. In addition to the several inches of rain that already fell
overnight across portions of central and southern New Jersey resulting
in flash flooding, an additional 2 to 4 inches can be expected today
through tonight for portions of northeast Pennsylvania and northern
New Jersey. Farther south across southeast Pennsylvania and southern
New Jersey, additional rain amounts of 1 to 2 inches are forecast on
top of what has already fallen so far. The greatest threat for flash
flooding this afternoon through tonight will be shifting into northern
New Jersey and northeast Pennsylvania where the heaviest additional
rain is expected; however, areas farther south may still experience
additional flash flooding as well. Finally, with a full moon this
weekend, minor coastal flooding is possible with the high tide this
evening.

Hazardous marine conditions are developing over the northern Atlantic
waters with strong winds, rough seas, and dangerous rip currents. Seas
will build to six to ten feet. A high risk for rip currents is
expected to continue today for the New Jersey and Delaware coasts.

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

* FLOODING RAIN:
Additional impacts from flooding rain are still a concern. Protect
against life-threatening rainfall flooding having possible extensive 
impacts across New Jersey and portions of eastern Pennsylvania. 
Potential impacts include:
    - Major rainfall flooding may prompt evacuations and rescues.
    - Rivers and tributaries may rapidly overflow their banks in
      multiple places. Small streams, creeks, canals, and ditches may 
      become dangerous rivers. In mountain areas, destructive runoff 
      may run quickly down valleys while increasing susceptibility to 
      rockslides and mudslides. Flood control systems and barriers may 
      become stressed.
    - Flood waters can enter many structures within multiple 
      communities, some structures becoming uninhabitable or washed 
      away. Many places where flood waters may cover escape routes. 
      Streets and parking lots become rivers of moving water with 
      underpasses submerged. Driving conditions become dangerous. 
      Many road and bridge closures with some weakened or washed out.

Protect against dangerous rainfall flooding having possible limited 
to significant impacts across southern New Jersey and portions of 
southeast Pennsylvania.

* WIND:
Little to no impacts are anticipated at this time across NEW 
JERSEY...DELAWARE...SOUTHEASTERN PENNSYLVANIA AND NORTHEAST MARYLAND.

* SURGE:
Little to no impacts are anticipated at this time across NEW 
JERSEY...DELAWARE...SOUTHEASTERN PENNSYLVANIA AND NORTHEAST MARYLAND.

* TORNADOES:
Little to no impacts are anticipated at this time across NEW 
JERSEY...DELAWARE...SOUTHEASTERN PENNSYLVANIA AND NORTHEAST MARYLAND.

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

If you are prone to flooding, be prepared for the possibility of a 
quick and dramatic rise in water levels.

It is important to remain calm, informed, and focused during an 
emergency. Be patient and helpful with those you encounter.

Closely monitor weather.gov, NOAA Weather radio or local news outlets 
for official storm information. Be ready to adapt to possible changes 
to the forecast. Ensure you have multiple ways to receive weather 
warnings.
