April 27, 2015 Extreme Weather Event Summary
WBRZ Baton Rouge, April 28, 2015: “Recent storm possibly in rare company”
A case could be made that the Monday Morning storm complex which tore across the
Gulf Coast was what's known as a derecho.
Somewhat uncommon, a derecho (pronounced deh-REY-cho)
is a long-lived, widespread wind storm associated with a
fast-moving line of thunderstorms. Although damage
produced by a derecho can appear similar to that of a
tornado, it is often observed in a straight path, hence the
term "straight-line" wind damage.

No Early Warning of this Weather Event – Only Slight to Moderate Risk
April 27-28 - Severe Thunderstorms - Southern Plains/ Lower
Mississippi Valley
Issued: Monday, April 27th 2015 3:08am CDT
StormWatch Threat Report
As of: Monday, April 27th 2015 7:43am CDT
Listing 2 threats affecting your configured locations.
Forecast Confidence:
Moderate to high
Changes From Previous Forecast:
Trimmed the western portion of the risk area.
Added a moderate risk across southern Louisiana.
Our Forecast:
A line of showers and thunderstorms is currently ongoing across the eastern
portions of Texas this morning in association with a potent upper-level
disturbance. Look for this activity to continue to spread eastward into the
Lower Mississippi Valley throughout the day with some redevelopment
possible back across east Texas this afternoon in the wake of this morning's
activity.
A moist and quite unstable environment combined with the disturbance and
daytime heating will support a risk for strong to severe thunderstorms with
strong damaging wind gusts, large hail, frequent cloud-to-ground lightning,
and isolated tornadoes being the primary threats. The latest guidance
indicates that the most favorable area for strong to severe storms this
afternoon and evening will be located across southern Louisiana where
moisture and instability is forecast to be maximized. Activity will likely
continue into the overnight hours, although a gradual decrease in
thunderstorm intensity is expected by late in the evening due to the loss of
daytime heating.
4
Main Impacts:
A localized and generally brief threat of power outages, property damage and
travel delays can be expected where the strongest thunderstorm activity
occurs.

NWS Cited Extreme Winds in Baton Rouge Area on April 27th
A National Weather Service Damage Assessment Team has surveyed
the storm damage in Baton Rouge, LA Metro Area. It has been
determined the damage was the result of strong straight line winds
that formed along the leading edge of a squall line. Damage estimates
were consistent with winds of 70-80 mph.
A broad area of wind damage was noted extending across Iberville,
West Baton Rouge, East Baton Rouge, Ascension, and Livingston
Parishes. Several power poles were either snapped or pushed over by
these strong winds.

Resources:
•
Entergy marshalled ~2,300 restoration resources to work as safely and quickly
as possible to restore power during this extreme weather event.
•
Restoration workers came from 25 different companies and 11 different states.

•
We procured all of the resources that we could, yet had to remain cautious not to flood the system with too9
many resources in tight zones in order to maintain a safe work environment.
Challenges and Outreach - April 27, 2015 Extreme Weather Event and Response Summary
Challenges:
• Widespread damage occurred across South Louisiana from Lake Charles to New
Orleans. The most severe damages occurred in the Baton Rouge area ,
Assumption and Northern Lafourche parishes and in Jefferson parish.
• Unlike a Hurricane there was no advanced warning to identify and secure
resources prior to the storm.
• Accessibility issues became a critical factor for restoration, requiring an
increased need for specialized equipment. Mostly due to waterways and rear
lot construction.
Damages in the bayou areas of
Assumption, Lafourche and St James
Parishes were difficult to access…..
Required special equipment like
swamp buggies and airboats
10
10
Challenges of Restoration in Rear Servitudes
•
In urban areas, rear lot construction is difficult to restore, due to the
limited access to facilities with line trucks.
o
o
Key examples include Baton Rouge, Metairie, Algiers and others.
Specialized equipment or climbing is needed
• Urban Baton Rouge areas have high tree density of
mature trees with large canopy. These factors and
the age of the neighborhoods cause more intensive
damages, which complicates and slows storm
restoration efforts. This is especially true where
rear lot overhead construction is involved.
• Baton Rouge has approximately 25% of its
distribution infrastructure in rear lot servitude
•
We have adequate special equipment for day to day needs, yet have to
request contractors and mutual assistance teams to bring in additional
specialized equipment to meet the excessive demands of storm damage.
o For example, in Baton Rouge we had companies bring in extra rear lot
specialized units, for a total of 13.
Damages in East
Baton Rouge Parish,
New Orleans and
Hammond areas
were heavy due to
tree canopy. These
required rear lot
equipment and
physically climbing.

Was This Storm a “ Derecho” ?
WBRZ Baton Rouge, April 28, 2015: “Recent storm possibly in rare company”
A case could be made that the Monday Morning storm complex which tore across the
Gulf Coast was what's known as a derecho.
1. Produce a swath of wind damage exceeding 240 miles
2. Include wind gusts of 58mph along most of its length
3. Include well separated wind gusts of 75mph or higher

Derecho Facts from NOAA Storm Prediction Center
• Derecho damage to overhead electric lines sometimes results in massive, longlasting power outages.
• Hundreds of thousands of people may be affected; in the worst events, power
may not be restored for many days.
• It is the complex and dense concentration of overhead distribution feeders in
urban areas --- and their frequent proximity to large trees --- that make cities
especially vulnerable to electrical outages following wind storms.
• The density and mileage of overhead electric distribution lines in urban areas far
exceeds that of any rural or exurban area.
• Pole lines often carry multiple circuits and voltages, as well as lines for street
lighting and customer service connections that further add to the vulnerability.
• Because of this, and because urban electrical feeders typically serve smaller
territories relative to their rural counterparts, significantly greater manpower is
necessary to restore service after major storms.
• Derecho damage may be widespread. As a result, repairs often require greater
effort, with additional delays related to shortages in supplies.

metro area, central and western Ohio, northeastern Kentucky,
southwestern Pennsylvania, West Virginia, northern, central, and
southwestern Virginia,[17] Maryland, Washington, D.C., Delaware
and southern New Jersey. In all the mentioned areas, many trees
uprooted or snapped, roofs became damaged, tents deployed to
sell fireworks leading up to the 4th of July Holiday collapsed, and
power outages were extensive, with over 4.2 million customers
losing power as a result.[18] [19] An Appalachian Power
representative described the power outage as the worst the
company had ever seen.[17] In total, 22 people were killed across
seven states and the District of Columbia.[20] At least six and
possibly seven of those deaths were in Virginia, all of them due to
fallen trees

Historical Derecho Events from NOAA Storm Prediction Center
JULY 22, 2003 DERECHO
"The Mid-South / Memphis Derecho of 2003“
• 80-102 mph gusts
• 2 deaths and 11 injuries – mostly due to fallen trees
• ~750,000 power outages across 5 states. Significant in Memphis, TN.
During the early morning of Tuesday, July 22, 2003, a derecho formed over north central
Arkansas and moved rapidly east-southeast, reaching northern Alabama by mid-morning
(Figure 1). Although the storm weakened over northern Alabama, it re-intensfied over
northwest Georgia and moved across northern and central Georgia into South Carolina
before ending by late afternoon. Many thousands of trees were damaged or blown down.
Two people were killed and 11 others were injured, mostly due to trees falling on homes
or vehicles.
Between 6 and 7 a.m. CDT Tuesday, the derecho passed through the Memphis,
Tennessee metropolitan area ("M" in Figure 1), producing some of the most intense
winds during its existence. Numerous homes and buildings were damaged, and at least
20 were destroyed. Power outages in the Memphis metropolitan area were extensive.
About 750,000 people (over 60 percent of the population) lost power, and three-quarters
of the regions's traffic signals ceased operation, causing chaotic traffic flow. Also, the
Memphis airport, an important hub for travelers and freight, had to be closed. It would
take two weeks for the entire metropolitan area to have power restored (Figure 2).
Figures 3-10 (below) were courteously provided by The Commercial Appeal (a Memphis
newspaper) and Scott McNeil. Given the amount of damage and extensive loss of
electricity, Shelby County, Tennessee (the county in which Memphis is located) was
declared a Federal Disaster Area.
