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

Tropical Storm Elsa is moving across southern Maryland tonight,
then will progress rapidly to our northeast on Friday.

The main threat will be from heavy rain with 1 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:
Potential impacts from the flooding rain are still unfolding across
some locations near and east of Interstate 95. Remain well guarded
against dangerous flood waters having possible significant impacts.
If realized, these 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.

Potential impacts from the flooding rain are still unfolding across
southern Maryland. Remain well guarded against locally hazardous
flood waters having additional limited impacts.

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 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:

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

If you are prone to flooding, 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.
