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

Tropical Storm Isaias is currently located over southern New York, and
quickly moving off to the northeast. Gusty winds up to 25 knots remain
possible over the Chesapeake Bay for the next couple of hours.

Moderate coastal flooding is likely along the western shores of the
Chesapeake Bay and at Washington DC Southwest Waterfront today. Minor
coastal flooding is likely along other tidal waters.

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

* SURGE:
Potential impacts from the main surge event are now unfolding across
along the tidal Potomac River and the Chesapeake Bay. 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 rip currents.
    - Minor to locally moderate damage to marinas, docks, boardwalks,
      and piers. A few small craft broken away from moorings.

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

* PREPAREDNESS INFORMATION:
If encountering a flooded roadway, turn around and don't drown. Most
flood deaths occur in vehicles.
