SITUATION OVERVIEW
------------------
At 1000 AM, Tropical Storm Barry forms in the northern Gulf of Mexico.
The storm center was located at 27.8N, -88.7W. This storm is expected
to continue slowly west through Friday, with an eventual turn to the
northwest expected early Saturday. Strengthening is forecast over the
next few days, with the potential for this storm to reach hurricane
strength right before landfall across the central coastline of
Louisiana.
POTENTIAL IMPACTS
-----------------
* FLOODING RAIN:
Protect against life-threatening rainfall flooding having possible
devastating impacts across southeast Louisiana and southern
Mississippi. Potential impacts include:
- Extreme rainfall flooding may prompt numerous evacuations and
rescues.
- Rivers and tributaries may overwhelmingly overflow their banks
in many places with deep moving water. Small streams, creeks,
canals, and ditches may become raging rivers. In mountain
areas, deadly runoff may rage down valleys while increasing
susceptibility to rockslides and mudslides. Flood control
systems and barriers may become stressed.
- Flood waters can enter numerous structures within multiple
communities, some structures becoming uninhabitable or washed
away. Numerous places where flood waters may cover escape
routes. Streets and parking lots become rivers of raging water
with underpasses submerged. Driving conditions become very
dangerous. Numerous road and bridge closures with some weakened
or washed out.
Protect against life-threatening rainfall flooding having possible
limited to extensive impacts across southeast Louisiana and southern
Mississippi.
* SURGE:
Protect against life-threatening surge having possible significant
impacts across extreme coastal southeast Louisiana and coastal
Mississippi.
Potential impacts in this area include:
- Areas of inundation with storm surge flooding accentuated by
waves. Damage to several buildings, mainly near the coast.
- Sections of near-shore escape routes and secondary roads become
weakened or washed out, especially in usually vulnerable low
spots.
- Major beach erosion with heavy surf breaching dunes. Strong and
numerous rip currents.
- Moderate damage to marinas, docks, boardwalks, and piers.
Several small craft broken away from moorings, especially in
unprotected anchorages.
Also, protect against locally hazardous surge having possible limited
impacts across extreme coastal southeast Louisiana and coastal
Mississippi.
Elsewhere across Southeast Louisiana and South Mississippi, little to
no impact is anticipated.
* WIND:
Protect against dangerous wind having possible significant impacts
across southeastern Louisiana. 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 southeastern Louisiana.
* TORNADOES:
Protect against a tornado event having possible limited impacts
across Southeast Louisiana and South 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.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
Listen to local official for recommended preparedness actions,
including possible evacuation. If ordered to evacuate, do so
immediately.
* OTHER PREPAREDNESS INFORMATION:
Storm surge is the leading killer associated with tropical storms and
hurricanes! Make sure you are in a safe area away from the surge
zone. Even if you are not in a surge-prone area, you could find
yourself cutoff by flood waters during and after the storm. Heed
evacuation orders issued by the local authorities.
Rapidly rising flood waters are deadly. If you are in a flood-prone
area, consider moving to higher ground. Never drive through a flooded
roadway. Remember, turn around don't drown!
Closely monitor weather.gov, NOAA Weather radio or local news outlets
for official storm information. Be ready to adapt to possible changes
to the forecast. Ensure you have multiple ways to receive weather
warnings.
