SITUATION OVERVIEW
------------------
TROPICAL STORM ISAIAS IS CURRENTLY LOCATED JUST OFFSHORE OF THE
NORTHEAST FLORIDA COAST. THE STORM IS EXPECTED TO CONTINUE NORTHWARD
ALONG THE EAST COAST. IT WILL LIKELY MOVE INLAND OVER THE CAROLINAS
THIS EVENING AND APPROACH OUR REGION BY LATE TONIGHT AND ESPECIALLY
TUESDAY. IMPACTS SHOULD DIMINISH BY WEDNESDAY MORNING.
THE MAIN THREATS WITH THIS SYSTEM ARE HEAVY RAINFALL LEADING TO FLASH
FLOODING AND SOME RIVER FLOODING, STRONG WINDS ESPECIALLY NEAR THE
COAST, MINOR TO POTENTIALLY MODERATE COASTAL FLOODING, AND DANGEROUS
MARINE CONDITIONS.
WE ARE MOST CONCERNED ABOUT FLASH FLOODING CAUSED BY 4 TO 6 INCHES OF
RAIN, AS WELL AS STRONG WINDS ALONG THE NEW JERSEY AND DELAWARE COASTS
WITH WIND GUSTS OF 60 TO 70 MPH POSSIBLE. SECONDARY THREATS INCLUDE
MINOR TO LOCALLY MODERATE COASTAL FLOODING, ESPECIALLY IN CHESAPEAKE
BAY, AS WELL AS THE POTENTIAL FOR ISOLATED TORNADOES. DANGEROUS RIP
CURRENTS AND 8 TO 12 FOOT SEAS ARE ALSO EXPECTED OVER THE WATERS.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
PROTECT AGAINST LIFE-THREATENING RAINFALL FLOODING HAVING POSSIBLE
EXTENSIVE IMPACTS ACROSS NORTHERN DELMARVA, WESTERN NEW JERSEY, AND
MUCH OF SOUTHEASTERN PENNSYLVANIA. POTENTIAL IMPACTS INCLUDE:
- MAJOR RAINFALL FLOODING MAY PROMPT WATER RESCUES.
- RIVERS AND TRIBUTARIES MAY RAPIDLY OVERFLOW THEIR BANKS IN
MULTIPLE PLACES. SMALL STREAMS, CREEKS, CANALS, AND DITCHES MAY
BECOME DANGEROUS RIVERS. IN HILLY TERRAIN, DESTRUCTIVE RUNOFF
MAY RUN QUICKLY DOWN VALLEYS WHILE INCREASING SUSCEPTIBILITY TO
ROCKSLIDES AND MUDSLIDES. FLOOD CONTROL SYSTEMS AND BARRIERS MAY
BECOME STRESSED.
- FLOOD WATERS CAN ENTER STRUCTURES WITHIN MULTIPLE COMMUNITIES,
SOME STRUCTURES BECOMING UNINHABITABLE OR WASHED AWAY. STREETS
AND PARKING LOTS MAY BECOME RIVERS OF MOVING WATER WITH
UNDERPASSES SUBMERGED. DRIVING CONDITIONS MAY BECOME DANGEROUS.
POSSIBLE ROAD AND BRIDGE CLOSURES WITH SOME WEAKENED OR WASHED
OUT.
PROTECT AGAINST DANGEROUS RAINFALL FLOODING HAVING POSSIBLE
SIGNIFICANT IMPACTS ACROSS COASTAL NEW JERSEY AND DELAWARE.
* WIND:
PROTECT AGAINST DANGEROUS WIND HAVING POSSIBLE SIGNIFICANT IMPACTS
ACROSS EASTERN NEW JERSEY AND CENTRAL AND SOUTHERN DELAWARE. POTENTIAL
IMPACTS IN THIS AREA 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.
ALSO, PROTECT AGAINST HAZARDOUS WIND HAVING POSSIBLE LIMITED IMPACTS
ACROSS NORTHERN DELAWARE, WESTERN NEW JERSEY, NORTHEAST MARYLAND, AND
SOUTHEASTERN PENNSYLVANIA.
* SURGE:
PROTECT AGAINST LOCALLY HAZARDOUS SURGE HAVING POSSIBLE LIMITED IMPACTS
ALONG DELAWARE BAY, THE TIDAL DELAWARE RIVER, NORTHEASTERN CHESAPEAKE
BAY, AND THE ATLANTIC COASTS OF 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.
* TORNADOES:
PROTECT AGAINST A TORNADO EVENT HAVING POSSIBLE LIMITED IMPACTS ACROSS
NEW JERSEY AND DELMARVA. 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.
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

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.
