NOAA’s Oil Spill Questions
What will happen to a hurricane that runs through
this oil slick?
• Most hurricanes span an enormous area of the
ocean (200-300 miles) — far wider than the
current size of the spill. [*Emphasis LQ: LQ’s note: So the size of both states of West Virginia and Maryland are under 200 – 300 sq miles? I don’t think so.]
• If the slick remains small in comparison to a
typical hurricane’s general environment and size,
the anticipated impact on the hurricane would
• The oil is not expected to appreciably affect either
the intensity or the track of a fully developed
tropical storm or hurricane.
• The oil slick would have little effect on the storm
surge or near-shore wave heights.
What will the hurricane do to the oil slick in
• The high winds and seas will mix and “weather”
the oil which can help accelerate the
• The high winds may distribute oil over a wider
area, but it is difficult to model exactly where the
oil may be transported.
• Movement of oil would depend greatly on the
track of the hurricane.
• Storms’ surges may carry oil into the coastline
and inland as far as the surge reaches. Debris
resulting from the hurricane may be contaminated
by oil from the Deepwater Horizon incident, but
also from other oil releases that may occur during
• A hurricane’s winds rotate counter-clockwise.
Thus, in VERY GENERAL TERMS:
o A hurricane passing to the west of the oil slick
could drive oil to the coast.
o A hurricane passing to the east of the slick
could drive the oil away from the coast.
o However, the details of the evolution of the
storm, the track, the wind speed, the size, the
forward motion and the intensity are all
unknowns at this point and may alter this

Hurricanes and the Oil Spill
Will the oil slick help or hurt a storm from
developing in the Gulf?
• Evaporation from the sea surface fuels tropical
storms and hurricanes. Over relatively calm water
(such as for a developing tropical depression or
disturbance), in theory, an oil slick could suppress
evaporation if the layer is thick enough, by not
allowing contact of the water to the air.
• With less evaporation one might assume there
would be less moisture available to fuel the
hurricane and thus reduce its strength.
• However, except for immediately near the source,
the slick is very patchy. At moderate wind speeds,
such as those found in approaching tropical
storms and hurricanes, a thin layer of oil such as
is the case with the current slick (except in very
limited areas near the well) would likely break into
pools on the surface or mix as drops in the upper
layers of the ocean. (The heaviest surface slicks,
however, could re-coalesce at the surface after the
• This would allow much of the water to remain in
touch with the overlying air and greatly reduce
any effect the oil may have on evaporation.
• Therefore, the oil slick is not likely to have a
significant impact on the hurricane.
Will the hurricane pull up
the oil that is below the
surface of the Gulf?
• All of the sampling to date
shows that except near
the leaking well, the
subsurface dispersed oil is in
parts per million levels or less. The hurricane will
mix the waters of the Gulf and disperse the oil
Have we had experience in the past with
hurricanes and oil spills?
• Yes, but our experience has been primarily with oil
spills that occurred because of the storm, not
from an existing oil slick and an ongoing release
of oil from the seafloor.
• The experience from hurricanes Katrina and Rita
(2005) was that oil released during the storms
became very widely dispersed.
• Dozens of significant spills and hundreds of
smaller spills occurred from offshore facilities,
shoreside facilities, vessel sinkings, etc.
Will there be oil in the rain related to
• No. Hurricanes draw water vapor from a large
area, much larger than the area covered by oil,
and rain is produced in clouds circulating

I cannot believe that there are those who will continue to make comparisons between Hurricane Katrina and other disasters…. the California ones were the first I had heard of a year or so back. Now?, it’s the flooding along the Red River.
The one thing that is common? Levees and misery.

Mississippi Hams Reflect on Hurricane Gustav, Prepare for Hanna and Ike
After several days of harrowing watching and waiting for Hurricane Gustav to make landfall, the storm slammed into southeast Louisiana Monday afternoon, leaving flooding, wind damage and power outages in its wake and evacuees eager to go home. As Amateur Radio operators across the area moved from an emergency response stance to clean-up, evaluation and repair, the need for some changes to operations and equipment became clear, as well as the vastly improved response as compared to Hurricane Katrina….

“…One problem noted by several officials in the area was the signal propagation from the Mississippi Emergency Management Agency (MSEMA) office near Jackson. “A new antenna up there would help,” said one. “We had a real hard time copying signal from MSEMA,” said another….”
“…Local hams were not the only ones learning lessons from the storm. Purvis noted that while the MSEMA official at the Stone County Emergency operations Center was familiar with Amateur Radio, the Federal Emergency Management Agency (FEMA) representative did not know anything about ham radio and the service that hams provide before the storm….”
