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

Tropical Storm Isaias, located over the Delmarva Peninsula, will
continue to move north-northeast along the Mid-Atlantic
coast. Isaias will slowly weaken as it accelerates northeast today,
crossing the local area this afternoon into this evening.

The main threats with this system include strong winds, heavy
rainfall, minor to moderate coastal flooding, as well as high surf and
dangerous rip currents. In addition, a few tornadoes are possible
through this afternoon.

Locally heavy rainfall is expected, with the heaviest rain expected
across portions of northeast New Jersey and the Lower Hudson Valley. A
widespread 1 to 3 inches of rain is possible for these locations, with
localized amounts up to 5 inches possible. Farther east, rainfall
amounts will average around 1 inch, with localized amounts up to
2 inches possible.

The strongest winds are likely to occur this afternoon across New York
City Metro, Long Island, northeast New Jersey, southern portions of
the Lower Hudson Valley, and southern 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 tonight.

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

* WIND:
Potential impacts from the main wind event are now unfolding across
the area. Remain well sheltered from dangerous wind having possible
significant impacts. If realized, these 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.


* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
northeast New Jersey and the Lower Hudson Valley. Remain well guarded
against life-threatening flood waters having possible extensive impacts.
If realized, these 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.


* SURGE:
Potential impacts from the main surge event are possible this evening.
Remain well away from locally hazardous surge having possible limited
impacts. If realized, these impacts 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:
Potential impacts from tornadoes are still unfolding across the region.
Remain well braced against a dangerous tornado event having possible
significant impacts. If realized, these impacts include:
    - The occurrence of scattered tornadoes can hinder the execution
      of emergency plans during tropical events.
    - Several places may experience tornado damage with a few spots
      of considerable damage, power loss, and communications failures.
    - Locations could realize roofs torn off frame houses, mobile
      homes demolished, boxcars overturned, large trees snapped or
      uprooted, vehicles tumbled, and small boats tossed about.
      Dangerous projectiles can add to the toll.


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

Now is the time to stay inside and away from windows. Listen for
updates and be ready in case you lose electrical power. Keep a
battery powered radio, charged cell phone and flashlight handy.

During the peak of the storm be ready to move quickly. Keep your
shoes on and rain gear handy. Boots and athletic shoes offer the best
foot protection if you become unexpectedly exposed to the weather.

Keep your cell phone charged and in power saving mode. If you lose
power, use it sparingly and mainly for personal emergencies and
checkins.

Do not be a thrill seeker or risk your life for photos or videos.

If you are prone to flooding or in an area under a storm surge watch
or warning, be prepared for the possibility of a quick and dramatic
rise in water levels.

If a tornado warning is issued for your area, quickly move to the
safest place within your shelter. Protect your head and body.
