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

Tropical Storm Isaias, located in inland Virginia, will continue
to move to north-northeast this morning along the Mid-Atlantic coast.
Isaias will slowly weaken as it accelerates northeast today, likely
moving over our area this afternoon and evening. However, confidence
continues to increase with respect to the magnitude of local hazards
and impacts.

The main threats with this system involve heavy rainfall, strong
winds, minor to moderate coastal flooding, along with high surf and
dangerous rip currents. Additionally, a few tornadoes are possible.

Locally heavy rainfall is expected with a widespread 1 to 3 inches,
with localized amounts up to 5 inches possible. The heaviest rain is
most likely to occur across New York City, Northeast New Jersey and
the Lower Hudson Valley this morning through this evening, and eastern
sections this afternoon into tonight. The strongest winds are likely
to occur across New York City Metro, Long Island, northeast New
Jersey, southern portions of the Lower Hudson Valley, and southeast
Connecticut. Dangerous marine conditions are likely across all of the
coastal waters today and tonight. High surf and dangerous rip currents
are expected to continue along the ocean beaches Today through
Wednesday.

The effects from Tropical Storm Isaias are expected to diminish
quickly from southwest to northeast across the area late tonight into
Wednesday morning.

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

* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
extensive impacts across New Jersey, New York City, the Lower Hudson
Valley, and portions of southeastern Connecticut. Potential impacts
include:
    - Major rainfall flooding may prompt many evacuations and rescues.
    - Rivers and streams may rapidly overflow their banks in multiple
      places. Small streams, creeks, canals, and ditches may become
      dangerous rivers. Flood control systems and barriers may become
      stressed.
    - In hilly terrain, destructive runoff may run quickly down
      valleys, and increase susceptibility to rockslides and
      mudslides.
    - 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.


* WIND:
Protect against dangerous wind having possible significant impacts
across Southeast New York, Northeast New Jersey, and Southern
Connecticut. Potential impacts in this area include:
    - Some damage to roofing and siding materials, along with damage
      to porches, awnings, carports, and sheds. A few buildings
      experiencing window, door, and garage door failures. Mobile
      homes damaged, especially if unanchored. Unsecured lightweight
      objects become dangerous projectiles.
    - Several large trees snapped or uprooted, but with greater
      numbers in places where trees are shallow rooted. Several
      fences and roadway signs blown over.
    - Some roads impassable from large debris, and more within urban
      or heavily wooded places. A few bridges, causeways, and access
      routes impassable.
    - Scattered power and communications outages, but more prevalent
      in areas with above ground lines

* SURGE:
Protect against locally hazardous surge having possible limited
impacts across shoreline communities. Potential impacts in
this area include:
    - Localized inundation with storm surge flooding mainly along
      immediate shorelines and in low lying spots, or in areas
      farther inland near where higher surge waters move ashore.
    - Sections of near shore roads and parking lots become overspread
      with surge water. Driving conditions dangerous in places where
      surge water covers the road.
    - Moderate beach erosion. Heavy surf also breaching dunes, mainly
      in usually vulnerable locations. Strong and frequent rip
      currents.
    - Minor to locally moderate damage to marinas, docks, boardwalks,
      and piers. A few small craft broken away from moorings.

Elsewhere across Southeast New York, Northeast New Jersey, and
Southern Connecticut, little to no impact is anticipated.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across Southeast New York, Northeast New Jersey, and Southern
Connecticut. Potential impacts include:
    - The occurrence of isolated tornadoes can hinder the execution
      of emergency plans during tropical events.
    - A few places may experience tornado damage, along with power
      and communications disruptions.
    - Locations could realize roofs peeled off buildings, chimneys
      toppled, mobile homes pushed off foundations or overturned,
      large tree tops and branches snapped off, shallow rooted trees
      knocked over, moving vehicles blown off roads, and small boats
      pulled from moorings.

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

Now is the time to check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.

Keep cell phones well charged. Cell phone chargers for automobiles
can be helpful, but be aware of your risk for deadly carbon monoxide
poisoning if your car is left idling in a garage or other poorly
ventilated area.

Rapidly rising flood waters are deadly. If you are in a flood prone
area, consider moving to higher ground. Never drive through a flooded
roadway. Remember, Turn Around Don`t Drown!

Storm surge is the leading killer associated with tropical storms and
hurricanes! Make sure you are in a safe area away from the surge
zone. Even if you are not in a surge prone area, you could find
yourself cut off by flood waters during and after the storm. Heed
evacuation orders issued by local authorities.

If in a place that is vulnerable to high winds, such as near large
trees, a mobile home, upper floors of a high rise building, or on a
boat, consider moving to a safer shelter before the onset of strong
winds or flooding.

If a Tornado Warning is issued for your area, be ready to shelter
quickly, preferably away from windows and in an interior room not
prone to flooding. If driving, scan the roadside for quick shelter
options.

Closely monitor http://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.

...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH LATE TONIGHT...

The Flash Flood Watch continues for

* Portions of southern Connecticut, northeast New Jersey, and
  southeast New York, including the following areas, in southern
  Connecticut, Northern Fairfield and Northern New Haven. In
  northeast New Jersey, Eastern Bergen, Eastern Essex, Eastern
  Passaic, Eastern Union, Hudson, Western Bergen, Western Essex,
  Western Passaic, and Western Union. In southeast New York,
  Bronx, Kings (Brooklyn), New York (Manhattan), Northern
  Queens, Northern Westchester, Orange, Putnam, Richmond (Staten
  Island), Rockland, Southern Queens, and Southern Westchester.

* Through late tonight

* Tropical Storm Isaias will track through the area today. A total
  of 1 to 3 inches of rain will be possible with locally higher
  amounts of up to 5 inches. Torrential downpours with multiple
  rounds of heavy showers will allow for excessive runoff and
  therefore would cause flash flooding in low lying, urban and
  poor drainage areas. Some rivers and streams across the path of
  the heavier rainfall axis could experience minor to moderate
  rises resulting in possible road closures and inundation of
  structures near the streams.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.
You should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.
