SITUATION OVERVIEW
------------------
Tropical Storm Isaias is moving off to the north northeast this
morning over north central North Carolina. The storm will continue to
move northward and will move through Eastern Virginia and the Delmarva
today and across New England Wednesday.
Conditions will deteriorate across the local area this morning.
Tropical storm force winds are possible today, especially along and
east of I-95. Wind gusts to 50 to 65 mph are possible. These winds
combined with the expected saturated soils could cause down trees and
power lines. In addition, heavy rainfall amounts of 3 to 6 inches
could cause areas of flash flooding even well inland. Localized minor
to moderate coastal flooding is also possible, with 1 to 3 feet of
inundation. Lastly, there is a risk of tornadoes today, mainly along
the coastal plain and eastern shore.
Tropical storm force winds are expected over the entire marine area
today with gusts as high as 60 knots. In addition, seas will build to
10 to 14 feet over the coastal waters today.
POTENTIAL IMPACTS
-----------------
* WIND:
Potential impacts from the main wind event are now unfolding across
eastern Virginia, the Maryland Eastern Shore, and northeast North
Carolina. Remain well sheltered from dangerous wind having possible
significant impacts. If realized, these impacts include:
- Some damage to roofing and siding, along with damage to
porches, awnings, carports, and sheds. Some buildings
experience window, door, and garage door failures. Mobile homes
damaged, some destroyed, especially if poorly anchored or
exposed to wind. Unsecured lightweight objects become dangerous
projectiles.
- Large trees snapped or uprooted, especially in areas where
soils are saturated. Some roadway signs will be blown over.
- Some roads will be impassable from large debris including
bridges, causeways, and access routes.
- Scattered to widespread power and communications outages.
* SURGE:
Potential impacts from the main surge event are now unfolding across
the east side of the Chesapeake Bay, Back Bay near Virginia Beach, and
the northern side of the Albemarle Sound. Remain well away from life-
threatening surge having possible significant impacts. If realized,
these impacts include:
- Severe storm surge flooding will likely cause inundation of
numerous roads and buildings, resulting in a threat to life and
property. Flooding will likely extend inland from the
waterfront and shoreline flooding homes, businesses and
isolating some neighborhoods. Large breaking waves will result
in additional damage near the shoreline.
- Numerous roads flooded or washed out.
- Major beach erosion with heavy surf breaching some dunes.
- Severe damage to marinas, docks, boardwalks, and piers is
expected. Small craft broken away from moorings, especially in
unprotected marinas and docks.
Elsewhere across CENTRAL AND EASTERN VIRGINIA...NORTHEAST NORTH
CAROLINA...AND THE LOWER MARYLAND EASTERN SHORE, little to no impact
is anticipated.
* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
Central and Eastern Virginia, as well as part of the Maryland Eastern
Shore. Remain well guarded against life-threatening flood waters having
possible extensive impacts. If realized, these impacts include:
- Evacuations and rescues likely due to flooding from heavy
rainfall
- Rivers and tributaries may rapidly overflow their banks in
multiple places. Small streams, creeks, and ditches may become
dangerous rivers. Flood control systems and barriers may become
overwhelmed.
- Flood waters enter structures within multiple communities, with
some structures becoming uninhabitable or washed away. Some
escape routes inundated by flood waters. Streets, parking lots
and underpasses could be submerged, with driving conditions
quickly becoming dangerous. Numerous road and bridge closures
are expected with some becoming weakened or washed out.
* TORNADOES:
Potential impacts from tornadoes are still unfolding across eastern
Virginia, the Maryland Eastern Shore and northeast North Carolina.
Remain well braced against a dangerous tornado event having possible
significant impacts. If realized, these impacts include:
- Some tornadoes are expected, some of which could be intense. As
a result, execution of emergency plans could be hindered in
affected areas.
- Several places may experience tornado damage, with a few areas
of considerable damage, power loss, and communications failures.
- Locations could realize roofs torn off frame houses, mobile
homes demolished, large trees snapped or uprooted, vehicles
tumbled, and small boats tossed about.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* OTHER PREPAREDNESS INFORMATION:
Now is the time to stay inside and away from windows. Listen for
updates and be ready in case you lose electrical power. Keep a battery-
powered radio, charged cell phone and flashlight handy.
During the peak of the storm be ready to move quickly. Keep your
shoes on and rain gear handy. Boots and athletic shoes offer the best
foot protection if you become unexpectedly exposed to the weather.
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.
Do not venture outside while in the eye of a hurricane as any
improvement in weather will only be temporary. Once the eye passes,
conditions will become life threatening as winds immediately return
to dangerous speeds, so remain safely sheltered from the storm.
Do not be a thrill seeker or risk your life for senseless photos or
videos.
Quickly move to the safest place within your shelter if it begins to
fail, preferably an interior room on the lowest floor as long as
flooding is not a concern.
If you are prone to flooding or in an area under a storm surge watch
or warning, 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.
If an Extreme Wind Warning is issued for your area, move to the
safest place within your shelter. Take the same life-saving actions
as if it were a violent tornado.
