    - POTENTIAL IMPACTS: Unfolding
        - Potential impacts from the main wind event are unfolding.

* STORM SURGE
    - LATEST LOCAL FORECAST: Localized storm surge possible
        - Peak Storm Surge Inundation: The potential for up to 2 feet
          above ground somewhere within surge prone areas
        - Window of concern: through this afternoon

    - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
      UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for storm
      surge flooding greater than 1 foot above ground
        - The storm surge threat has remained nearly steady from the
          previous assessment.
        - PLAN: Shelter against storm surge flooding greater than 1
          foot above ground.
        - PREPARE: All flood preparations should be complete. Expect
          flooding of low-lying roads and property.
        - ACT: Stay away from storm surge prone areas. Continue to
          follow the instructions of local officials.

    - POTENTIAL IMPACTS: Unfolding
        - Potential impacts from the main surge event are unfolding.

* FLOODING RAIN
    - LATEST LOCAL FORECAST: Flash Flood Watch is in effect
        - Peak Rainfall Amounts: Additional 2-4 inches, with locally
          higher amounts

    - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
      UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for
      moderate flooding rain
        - The flooding rain threat has remained nearly steady from
          the previous assessment.

          swifter currents and overspill their banks in a few places,
          especially in usually vulnerable spots. Small streams,
          creeks, canals, arroyos, and ditches overflow.
        - Flood waters can enter some structures or weaken
          foundations. Several places may experience expanded areas
          of rapid inundation at underpasses, low-lying spots, and
          poor drainage areas. Some streets and parking lots take on
          moving water as storm drains and retention ponds overflow.
          Driving conditions become hazardous. Some road and bridge
          closures.

* TORNADO
    - LATEST LOCAL FORECAST:
        - Situation is somewhat favorable for tornadoes

    - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST

      tornadoes
        - The tornado threat has remained nearly steady from the
          previous assessment.
        - PLAN: Emergency plans should continue to include possible
          tornadoes.
        - PREPARE: Stay within your shelter keeping informed of the
          latest tornado situation.
        - ACT: Move quickly to the safest place within your shelter
          if a tornado warning is issued.

    - POTENTIAL IMPACTS: Limited
        - 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.

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

Heavy rain leading to flooding will be possible, especially along and
southeast of the Interstate 95 corridor due to Tropical Storm Fay.
Tropical Storm Fay is currently off the Virginia coast. It is expected
to progress north over our region through Friday. Heavy rain is
possible beginning very late tonight and continuing through Friday
evening. The threat for tropical storm winds over land is very low
except right along the New Jersey coast.

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

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible significant
impacts along and southeast of the Interstate 95 corridor. Potential
impacts include:
    - Moderate rainfall flooding may prompt several evacuations and
      rescues.
    - Rivers and tributaries may quickly become swollen with swifter
      currents and overspill their banks in a few places, especially
      in usually vulnerable spots. Small streams, creeks, canals,
      arroyos, and ditches overflow.
    - Flood waters can enter some structures or weaken foundations.
      Several places may experience expanded areas of rapid
      inundation at underpasses, low-lying spots, and poor drainage
      areas. Some streets and parking lots take on moving water as
      storm drains and retention ponds overflow. Driving conditions
      become hazardous. Some road and bridge closures.

* TORNADOES:
Protect against a tornado event having possible limited impacts across
New Jersey and southeastern Pennsylvania. 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.

* WIND:
Protect against hazardous wind having possible limited impacts across
coastal New Jersey. Potential impacts in this area include:
    - Damage to porches, awnings, carports, sheds, and unanchored
      mobile homes. Unsecured lightweight objects blown about.
    - Many large tree limbs broken off. A few trees snapped or
      uprooted, but with greater numbers in places where trees are
      shallow rooted. Some fences and roadway signs blown over.
    - A few roads impassable from debris, particularly within urban
      or heavily wooded places. Hazardous driving conditions on
      bridges and other elevated roadways.
    - Scattered power and communications outages.

Elsewhere across NEW JERSEY...DELAWARE...SOUTHEASTERN PENNSYLVANIA
AND NORTHEAST MARYLAND, little to no impact is anticipated.

* SURGE:
Protect against locally hazardous surge having possible limited impacts
across coastal New Jersey and Delaware. 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 rip currents.
    - Minor to locally moderate damage to marinas, docks, boardwalks,
      and piers. A few small craft broken away from moorings.

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



* OTHER PREPAREDNESS INFORMATION:
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!

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 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.

Yes it is! Getting some heavier rain here now, with some occasional breezes - feels practically stormy at times. Just crossed the 1" mark rain-wise.

Moderate to occasionally heavy rain here. Approaching .50" at noon.

Impressive little storm. Makes you wonder what Fay might have been capable of if this were 9/10 instead.
