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

Tropical Storm Elsa is currently moving to the northeast and into
central NC. Elsa will continue quickly moving to the northeast
tracking through the Mid-Atlantic through this evening, before passing
over southern Maryland tonight. Elsa is expected to rapidly move
off to our northeast on Friday.

The main threat will be from heavy rain with 2 to 3 inches most likely
and isolated totals as high as 5 inches across southern Maryland.
Moderate to heavy rainfall over a few hours may cause streams and
creeks to quickly rise out of their banks.

An isolated tornado is possible, especially across extreme southern
Maryland near the Chesapeake Bay and lower Tidal Potomac River. There
is also an isolated threat for waterspouts over the waters.

Tropical Storm force winds are most likely over the waters and along
the immediate shoreline of eastern Calvert and southeast St Marys
Counties.

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

* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts east of Interstate 95. 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.

Elsewhere across Eastern West Virginia, Central and Western Maryland,
Northern and Northwestern Virginia, and District of Columbia, little
to no impact is anticipated.

* WIND:
Protect against hazardous wind having possible limited impacts across
southern Maryland. 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 Eastern West Virginia, Central and Western Maryland,
Northern and Northwestern Virginia, and District of Columbia, little
to no impact is anticipated.

* TORNADOES:
Protect against a tornado event having possible limited impacts
across extreme southern Maryland. 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.

Elsewhere across Eastern West Virginia, Central and Western Maryland,
Northern and Northwestern Virginia, and District of Columbia, little
to no impact is anticipated.

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. Ensure 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!

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.

If in a place that is vulnerable to high wind, such as near large
trees, a manufactured 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.

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.
