SITUATION OVERVIEW
------------------
Tropical Storm Isaias is currently in the southwest Gulf and will
continue to strengthen as it moves to the east-northeast and
eventually the northeast through Friday. Tropical Storm Isaias is
forecast to bring the threat of tropical storm force wind gusts,
locally heavy rainfall, and storm surge of 3 to 5 feet to coastal
portions of southeast Louisiana from the mouth of the Mississippi
River to the Rigolets and from Bay Saint Louis westward in coastal
Mississippi. Isaias is forecast to bring the threat of hurricane force
wind gusts, locally heavy rainfall, and storm surge of 5 to 7 feet
from Bay Saint Louis eastward in coastal Mississippi. The most likely
time for impacts will be Friday into Saturday.
Storm surge watches have been issued from the mouth of the Mississippi
River to the Alabama and Mississippi state line. Hurricane watches are
in effect from Ocean Springs to the Alabama and Mississippi state
line. Tropical storm watches are in effect from the Jefferson and
Plaquemine Parish line in southeast Louisiana to Ocean Springs in
coastal Mississippi.
POTENTIAL IMPACTS
-----------------
* WIND:
Prepare for life-threatening wind having possible extensive impacts
for locations east of Ocean Springs in coastal Mississippi.
Potential impacts in this area include:
- Considerable roof damage to sturdy buildings, with some having
window, door, and garage door failures leading to structural
damage. Mobile homes severely damaged, with some destroyed.
Damage accentuated by airborne projectiles. Locations may be
uninhabitable for weeks.
- Many large trees snapped or uprooted along with fences and
roadway signs blown over.
- Some roads impassable from large debris, and more within urban
or heavily wooded places. Several bridges, causeways, and
access routes impassable.
- Large areas with power and communications outages.
Also, prepare for dangerous wind having possible limited to
significant impacts for locations west of Ocean Springs in coastal
Mississippi and for extreme coastal portions of southeast Louisiana
from the mouth of the Mississippi River eastward.
Elsewhere across Southeast Louisiana and South Mississippi, little to
no impact is anticipated.
* SURGE:
Prepare for life-threatening surge having possible extensive impacts
for coastal locations east of Ocean Springs in coastal Mississippi. Potential
impacts in this area include:
- Large areas of deep inundation with storm surge flooding
accentuated by battering waves. Structural damage to buildings,
with several washing away. Damage compounded by floating
debris. Locations may be uninhabitable for an extended period.
- Large sections of near-shore escape routes and secondary roads
washed out or severely flooded. Flood control systems and
barriers may become stressed.
- Severe beach erosion with significant dune loss.
- Major damage to marinas, docks, boardwalks, and piers. Many
small craft broken away from moorings, especially in
unprotected anchorages with some lifted onshore and stranded.
Also, prepare for locally hazardous surge having possible significant
impacts for coastal locations west of Ocean Springs in coastal Mississippi
and for locations outside of the hurricane risk reduction system in southeast
Louisiana from the Pearl River south to the mouth of the Mississippi.
Elsewhere across Southeast Louisiana and South Mississippi, little to
no impact is anticipated.
* FLOODING RAIN:
Prepare for life-threatening rainfall flooding having possible
extensive impacts for locations in Jackson County in coastal Mississippi.
Potential impacts include:
- Major rainfall flooding may prompt many evacuations and rescues.
- Rivers and tributaries may rapidly overflow their banks in
multiple places. Small streams, creeks, canals, and ditches may
become dangerous rivers. Flood control systems and barriers may
become stressed.
- Flood waters can enter many structures within multiple
communities, some structures becoming uninhabitable or washed
away. Many places where flood waters may cover escape routes.
Streets and parking lots become rivers of moving water with
underpasses submerged. Driving conditions become dangerous.
Many road and bridge closures with some weakened or washed out.
Prepare for dangerous rainfall flooding having possible limited to
significant impacts for the rest of coastal Mississippi.
Elsewhere across Southeast Louisiana and South Mississippi, little to
no impact is anticipated.
* TORNADOES:
Prepare for a tornado event having possible limited impacts across coastal
Mississippi. 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 Southeast Louisiana and South Mississippi, little to
no impact is anticipated.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
Follow the advice of local officials.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to check your emergency plan and emergency supplies
kit and take necessary actions to protect your family and secure your
home or business.
When making safety and preparedness decisions, do not focus on the
exact forecast track since hazards such as flooding rain, damaging
wind gusts, storm surge, and tornadoes extend well away from the
center of the storm.
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, plan to move to safe shelter.
If you live in a place particularly vulnerable to flooding, such as
near the ocean, in a low-lying or poor drainage area, plan to
move to safe shelter on higher ground.
When securing your property, outside preparations should be concluded
as soon as possible before conditions deteriorate. The onset of
strong gusty winds or flooding can cause certain preparedness
activities to become unsafe.
Be sure to let friends and family members know of your intentions for
weathering the storm and your whereabouts. Have someone located away
from the threatened area serve as your point of contact. Share vital
contact information with others. Keep cell phones handy and charged.
Check on those who may not be fully aware of the situation or who are
unable to make personal preparations.
If you are a visitor, know the name of the county or parish in which
you are located and where it is relative to current watches and
warnings. If staying at a hotel, ask the management staff about their
onsite disaster plan. Listen for evacuation orders, especially
pertaining to area visitors.
Closely monitor weather.gov, NOAA Weather Radio and local news
outlets for official storm information. Listen for possible changes
to the forecast.
