SITUATION OVERVIEW
------------------
...OVERVIEW...At 4 PM CDT, Hurricane Nate is moving toward
the north- northwest near 23 mph as a strong Category 1 hurricane
with 90 mph winds, and is expected to pass over portions of Lower
Plaquemine Parish in the next few hours. Hurricane Nate is then
expected to make landfall tonight along the Mississippi
Coast. The main impacts across southeast Louisiana and southern
Mississippi will be damaging winds and storm surge flooding along
the immediate coast and tidal locations.
POTENTIAL IMPACTS
-----------------
* SURGE:
Potential impacts from the main surge event are now unfolding across
the immediate Mississippi coast and across parts of
Southeast Louisiana east of the Mississippi River outside of the
hurricane risk reduction levee system including portions of
Plaquemines, St. Bernard, Orleans, and far Southeastern St. Tammany
Parishes. Remain well away from life-threatening
surge having possible devastating impacts. If realized, these impacts
include:
- Widespread deep inundation, with storm surge flooding greatly
accentuated by powerful battering waves. Structural damage to
buildings, with many washing away. Damage greatly compounded
from considerable floating debris. Locations may be
uninhabitable for an extended period.
- Near-shore escape routes and secondary roads washed out or
severely flooded. Flood control systems and barriers may become
stressed.
- Extreme beach erosion. New shoreline cuts possible.
- Massive damage to marinas, docks, boardwalks, and piers.
Numerous small craft broken away from moorings with many lifted
onshore and stranded.
Potential impacts from the main surge event are also now unfolding
across the immediate shoreline of Lake Pontchartrain and along the
Southeast Louisiana coast west of the Mississippi River to
Grand Isle. Remain well away from life-threatening surge having
possible significant to extensive impacts.
* WIND:
Potential impacts from the main wind event are now unfolding across
Mississippi coastal counties of Jackson, Harrison,
and Hancock as well as portions of extreme Southeast Louisiana
including much of Lower Plaquemines and Lower St. Bernard
Parishes. Remain well sheltered from life-threatening wind having
possible extensive impacts. If realized, these impacts 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.
Potential impacts from the main wind event are also now unfolding
across across inland areas of southern Mississippi
mainly east of the Interstate 55 corridor including Pearl River County
and parishes east of Interstate 55 corridor in Southeast Louisiana
including metro New Orleans.. Remain well sheltered from
dangerous wind having possible limited to significant impacts.
* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
Southeast Louisiana and South Mississippi. Remain well guarded
against locally hazardous flood waters having possible limited impacts.
If realized, these impacts include:
- Localized rainfall flooding may prompt a few evacuations.
- Rivers and tributaries may quickly rise with swifter currents.
Small streams, creeks, canals, bayous, and ditches may become
swollen and overflow in spots.
- Flood waters can enter a few structures, especially in usually
vulnerable spots. A few places where rapid ponding of water
occurs at underpasses, low-lying spots, and poor drainage
areas. Several storm drains and retention ponds become
near-full and begin to overflow. Some brief road and bridge
closures.
* TORNADOES:
Potential impacts from tornadoes are still unfolding across the
Mississippi coastal counties and extreme Southeast Louisiana including
Lower Plaquemines and Lower St. Bernard Parishes. Remain well braced
against a tornado event having possible limited impacts. If realized,
these 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:
IMMINENT/ONGOING PHASE - Do not return to evacuated areas until
hazardous winds diminish and flood waters abate.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to remain safely sheltered from the storm. Stay
inside and away from windows. Listen for updates and be ready in case
you lose electrical power. Locate your battery powered radio and
flashlight from your Emergency Supplies Kit. Keep these items close.
During the peak of the storm, keep your shoes on and rain gear handy.
Boots and tennis shoes offer the best foot protection if you become
unexpectedly exposed to the elements.
Continue to keep your cell phone well charged for as long as
possible. If you lose power, use it more sparingly and mainly for
personal emergencies and check-ins. Do not overload communications
systems with idle chatter.
Do not venture outside while in the eye of a hurricane. Within the
eye, weather conditions may temporarily improve which can be
misleading. Once the eye passes, the wind will change direction and
return to dangerous speeds. Heavy rain will also return. Be smart and
remain safely hidden from the storm.
Do not be a thrill seeker or risk your life for senseless photos or
videos. Be wise and avoid becoming another statistic.
