DEEPWATER HORIZON INCIDENT& NATIONAL WEATHER SERVICE DECISION SUPPORT SERVICES
WFO New Orleans/Baton RougeApril 21, 2010 – October 15, 2010
THE EVENT On the night of April 20, 2010,
the semi-submersible production petroleum platform “Deepwater Horizon” exploded during a drilling operation.
After burning intensely for 36 hours, the rig sank on the 22nd, resulting in a massive oil spill from the ruptured well head.
Well head located 5000 feet deep over the Macondo Dome on the edge of the Continental Shelf.
Macondo Well over 18,000 feet deep.
WFO NEW ORLEANS/BATON ROUGE (LIX) ENGAGEMENT The office received a call from
the U.S. Coast Guard, notifying us of the incident shortly after the initial explosion.
USCG requested a detailed weather forecast for the location – Mississippi Canyon 252 oil lease area, Lat 28.74N and Lon 88.44W.
The NOAA Office of Response and Restoration (OR&R) requested the initial spot forecast on April 21st.
The Spot Forecast would be produced twice a day for much of the entire incident response.
DEPLOYING TO INCIDENT COMMAND Not automatic!!! ‘Not needed’
initially by BP Had to gain trust
and prove performance
Rapport with USCG and other federal agencies was key.
BATTLE RHYTHM
Started out a 24 hour cycle Around day 75 – 2 day cycle Around day 98 – 4 day cycle After static kill - a 7 day cycle
ORGANIZATIONAL CHART (AN EXAMPLE)
NWS and NOAA
MULTIPLE ASPECTS OF FORECASTING Aviation
Low level dispersion flights 2nd level spotter flights Mid-level reconnaissance flights Terminal forecasts for non-TAF locations
Hancock County-Stennis Airport (MS) Terrebonne-Houma Regional Airport (LA)
Marine Near shore in protected and unprotected waters Offshore spill location (62nm from mouth of the MS River)
Fire Weather In-situ burning of oil on water
Heat Stress Oil clean-up in Tyvek protective covering during summer Outsider assistance not accustomed to Gulf humidity
MULTI-LAYERED AVIATION Over flights Reconnaissance Dispersant Flights
Use of tstm outflow boundaries
VIP over flights Animal/Wildlife
search and rescue
DECISION SUPPORT MODIFICATIONS Emergency TAFs for staging airfields
Terrebonne-Houma Regional Airport, Houma, LA Incident Command Center location Overflight and surveillance flight operations
Hancock County – Stennis Airport, Stennis, MS Military dispersant flight staging Government VIP staging
Presidential Visit toVenice, LA “Synthetic” TAF temporarily
established for Boothville-Venice ASOS location to support POTUS logistics.
MULTI-NATIONAL EFFORT
Canadian Coast Guard and Icelandic Coast Guard
SLAR over flights for intelligence gathering on daily spill footprint.
Weather sensitive for winds and seas
IN-SITU BURNS Not your typical
wildfire or prescribed burn
Critical operating levels based on wind direction and sea state
Main motivation for the hourly spot forecasts issued every day by WFO LIX
AVIATION WEATHER BRIEFINGS Most operations
were heavily dependent on weather decision support
Most often weather was the GO/NO GO factor on a daily basis
MARINE SUPPORT
Vessels of Opportunity (VOO) Fleet
Boom Deployment near shore
Deepwater fleet – many vessels in tight operations area
INTELLIGENCE GATHERING
WFO LIX prepared a daily overflight forecast to aid in satellite imaging data quality
HEAT STRESS Very critical factor to beach cleaning limitations 40-20 rule and 20-40 rule No Tyvek covering
40 minutes each hour, 20 minutes of supervised rest in a tent.
Full Tyvek protection 20 minutes work each hour,
40 minutes of supervised rest in a tent.
Numerous Heat Advisory Days during the episode
Most event related injuries/illness were heat stress related (about 40% of all reportable injuries).
TROPICAL THREATS Tropical Storm Bonnie July 23-25 A direct threat to the
area of operations Weakened before
moving over operations area
Prompted a 3 day shut-down of operations at the source
A 1 day Shelter-in-place stand down at Houma ICC.
TROPICAL THREATS Tropical Depression Five August 10-11 A direct threat to the
area of operations Dissipated before
making landfall Still prompted a 3 day
shut-down of operations at the source
A 1 day stand-down, shelter in place at Houma ICC.
WILDLIFE RESCUES
SEAFOOD QUALITY
NOAA LINE OFFICE COLLABORATION
NOS - Office of Coast Survey Oil Trajectory forecast maps produced daily
NOAA – Office of Response and Restoration Initiated 2-a-day spot forecast requests Frequent teleconference weather briefings
NOS / USCG weather briefings for decon operations

MEDIA INTERVIEWS AND BRIEFINGS
Oil vs Hurricanes; Hurricanes and oil Talking points generated by
NHC/WSH/NOAA. Formal briefings:
approximately 1200 Informal briefings:
approximately 5000 International, national and
local media interviews: 150 Often became overwhelming
from a workload standpoint. Recommend bringing in a
Public Affairs or HQ person to handle interviews.
MEANWHILE, BACK AT THE OFFICE Initiated the ER-Met Desk
Two event coordinators appointed by MIC 24 hr coverage – 2 twelve hour shifts
Fire Weather Spot Forecast formatter modified In addition to traditional grid based parameters… TAFs for aviation ops staging terminals 3 day Areal Aviation Outlook Sounding data to support in-situ burning ops Tide information Radar summary Watch/Warning/Advisory Summary Issued hourly from 0500 to 1900
MAKING IT WORK
Enacted an emergency schedule to account for 4 forecasters out of the regular rotation
National and regional assistance with back fill staffing All product templates were developed ‘on-the-fly’ to
meet specific forecast needs Back-fill staff contributed greatly to the success of
this undertaking by bringing skills and best practices into the local operations!
Web page presence developed at WFO LIX by intern Shawn O’ Neil (pictured above).
HOURLY SPOTS Originally generated for the
spill location NOS – OCS requested two
shore-based spot forecasts for shoreline clean up and harbor boom deployment Port Fourchon spot for
waters west of the MS River Hopedale spot for the LA
sounds east of the MS River Issued from 0400 through
sunset each day Sensitivities with LOOP facilities
serviced out of Port Fourchon, LA
Last hourly spot issued Aug 24th
3,920 hourly spots issued for entire event.
ACROSS THE BOARD CONTRIBUTIONS Virgil Middendorf – WFO Boise, ID
Assisted greatly with Spot Forecast formatter modifications
Angel Montenez – WFO Birmingham, AL Added and modified grid fields and AWIPS
workfiles to facilitate Spot Forecast generation WSH Office of Hydrology
Provided scripting to parse tide data from RiverPro hydro database
SRH – brought in team to make local Active Directory work more efficiently.
BACK FILL CONTRIBUTIONS 44 forecasters TDY to WFO LIX; others to
MOB. IMETs deployed to Forward Operations
Branch (FOB) in Venice, LA IMET briefly deployed to Houma ICC
ICS role not well suited to typical Fire IMET functions
Lack of familiarization with local environment and government landscape
Different weather regime - heavily marine oriented
Tide tables developed by back fill (HGX) GIS based gridded data developed by LCH
back fill (also assisted in emergency relief at ICC)
GIS GENERATED GRAPHICS
o Expedited GIS programming provided by WFO LCH Service Hydrologist – Jonathan Brazzell and LMRFC DOH – David Welch
o Produced automatically by cron on local GIS box; posted to web
WEB PAGE DEVELOPMENT Originally posted basic
information and forecasts to existing EM briefing page
Intern with web design skills added thumbnails and Google maps capabilities.
Page was posted on Whitehouse.gov site
Became the ‘go-to’ page for NWS spill response
Hit count: 102,838 thru 10/7/10.

NWSEO ROLE LOT efforts to implement emergency
schedule Some concessions to accommodate deployed
and back-fill transitions NWSEO President visited the WFO LIX and
toured Houma ICC on August 12th.
SIMULTANEOUS INCIDENT RESPONSES
Mar 30 (pre-spill): Denham Springs Petroleum Warehouse Fire July 30: Mud Lake in Barataria Bay
pipeline leak
Sep 2: Another Rig explosion south of Cameron, LA
Aug 12: Paincourtville, Assumption Parish, LA gas leak (108 spots issued)
Aug 10: Norco Motiva Sulfuric Acid leak
Aug 9: New Orleans East train derailment – 19 cars involved
CONTINUITY OF OPERATIONS (COOP) Instructions and templates posted to SRH
Sharepoint NWSChat used extensively
Deepwateroilchat room established early on and exclusively for Gulf NWS offices only and ICC/ICP.
NDBC was added to NWSChat and utilized for buoy data quality collaboration.
Cross training with office visits from WFO MOB personnel.
Back fill mets exposed to ICS activities Some visited the Houma ICC
MISCELLANEOUS FACTORS Fatigue Long days (12-15 hours) Fast paced Not the typical NWS routine Many consecutive days without a break Areal familiarity crucial Ability to be flexible Readiness for other responses Tropical Weather Staff training/drills Other “routine” operations
FUTURE CONSIDERATIONS Decision Support Services need…
Turnkey approach to forecast product formatters Portability for ICC or UAC deployment Flexibility in policies and protocols to best fit the situation
DSS should have robust GIS capabilities and fully integrated data sources.
ER-Mets not equivalent to I-Mets in skill sets for all situations
Staffing Area Command FOB – Imets ICC – local WFO UAC – RH or WSHQ
Equipment should be prepared and ready prior to deployment (Active Directory and security issues)
SUMMARY Largest emergency Response in U.S. History
Deepwater Horizon Rig Explosion and ensuing massive oil spill.
NWS was a key component of federal response, along with other NOAA line offices.
Local WFOs provided critical and unprecedented Decision Support Services for their respective AOR.
