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

Tropical Storm Isaias, located off the north Florida coast, will
continue to move to the north this morning, turning north-northeast
this afternoon along the southeast coast. Isaias will continue moving
northeast tonight over Eastern North Carolina. Isaias will slowly
weaken as it accelerates northeast on Tuesday, likely moving over our
area Tuesday afternoon and evening. There is still some timing and
intensity uncertainty with this storm. 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.

Locally heavy rain is expected with a widespread 2 to 4 inches,
with localized amounts up to 6 inches possible. The heaviest rain is most
likely to occur across New York City, Northeast New Jersey and the Lower Hudson
Valley early Tuesday morning through Tuesday evening, and eastern sections Tuesday
afternoon into Tuesday night. The strongest winds are likely to occur across Long
Island, southern Westchester and southern Connecticut, and the New
York City and New Jersey Metro areas. Dangerous marine conditions are
likely across all of the coastal waters Tuesday and Tuesday night. High
surf and dangerous rip currents are expected along the ocean beaches
Monday through Wednesday.

The effects from Tropical Storm Isaias are expected to diminish
quickly from southwest to northeast across the area Tuesday night.

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

* FLOODING RAIN:
Prepare for life-threatening rainfall flooding having possible
extensive impacts across northeast New Jersey, New York City, and the
Lower Hudson Valley. 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:
Prepare for dangerous wind having possible significant impacts across
Southeast New York, Northeast New Jersey, and Southern Connecticut.
Potential impacts 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:
Prepare for 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.

* TORNADOES:
Prepare for 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
----------------------------------

* OTHER PREPAREDNESS INFORMATION:

Now is the time to complete all preparations to protect life and
property in accordance with your emergency plan. Make sure you are in
a safe location before the onset of strong winds or possible flooding.

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.
