Kevin
Stewart, Chairman, National Hydrologic Warning Council
Excerpts from National Hydrologic Program Managers Conference, December
3, 2002
What I see about AHPS and my involvement is that the business of hydrology
in the National Weather Service has been elevated to a much higher platform.
I'm sure glad to see this, but we haven't plateaued yet. What I would
like to share is a perspective of how we [state & local partner
agencies] view our relationship with the National Weather Service.
Why is there so much national interest in floods? Floods are kind of
a big deal and they do impact our economy very heavily. Considering all
weather-related disasters, they are a big killer and you all know that.
Floods cost our nation between $4-5 billion annually. In some years, floods
can cost that much in a week [e.g. Tropical Storm Allison]. Seventy
to eighty percent of presidential declared [natural] disasters
are flood related.
Now, step back and look at the insurance business that has been created
by the United States federal government under FEMA. There is over $600
billion of coverage in the United States today--and it is interesting
to note that twenty percent of flood insurance claims occur in areas that
have not been identified
as flood prone. What this tells me as an engineer is that we have a long
way to go in mapping and understanding our hazards. What we do know is
that the impact of water on our society does affect our economy in all
sorts of ways.
How many have attended an ALERT users conference--about 50% maybe? If
you get a chance, take advantage of it. We need to get you all more involved
with these users group conferences. Here is what is important about them.
You will meet your constituency groups at these user conferences. There
are three main user groups in the United States, the ALERT Users Group
[AUG] on the West Coast, the Southwestern Association of ALERT
Systems [SAAS], and in the East you have the ALERT~FLOWS East
Coast Users Group which deals with both the ALERT and IFLOWS technologies.
Put these acronyms aside and what are we talking about? We are talking
about local data and local data acquisition directed primarily at hydrologic
services. The services that you provide in your day-to-day job depend,
not exclusively, but to a high degree on hydrologic data provided by others.
You [the National Weather Service] do not pay for a high percentage
of this data, but you use it in providing [flood] forecasts and
warnings to the nation.
I think a watershed year to note was 1972. I say this because a lot of
what is going on in the United States today with locals getting involved
in the detection business--actually buying gages, putting systems in,
evaluating the data--came out of the Rapid City flash flood. It [ALERT
development and implementation] really came out of the Western Region
of the National Weather Service. The Western Region Director [in 1972]
knew there was dialogue taking place out West about this idea of locals
being involved in measuring rainfall, doing some things, and the State
of California was involved as well. After the Rapid City flood, he came
home [from a Rapid City vacation taken during the flood] with
a whole new appreciation that maybe we ought to do this local flood warning
thing a little quicker. So, the business of locals contributing to the
flood warning process came out of an action following the 1972 Rapid City
Flood in the middle part of the United States. Communities in California
acted on things very quickly by deploying and implementing what is today
called ALERT Systems.
The other thing that happened in 1972 was Hurricane Agnus. So, if you
look at Hurricane Agnus out East and the 237 people in middle part of
the United States that were killed in the Rapid City flash flood, events
like these tend to get Congress' attention. And that's really what happened.
It [these events] didn't have much affect on the National Weather
Service at that time, but it had a tremendous impact on the National Flood
Insurance Program. In 1973, Congress passed the Flood Disaster Protection
Act. That was a direct response to Hurricane Agnus and Rapid City. This
[1972] was definitely a watershed year in the flood insurance
program.
For flash floods our lead times are very short. We need to have more
people sensitive to the problems of early warning. We need to have notification
before the onset of flooding.
We want our emergency managers mobilized or at least at a very high level
of awareness before it rains. Local officials are learning early detection
triggers and thresholds to monitor. For example, local public safety and
public works officials monitor temperatures and dew points hourly to determine
if the forecast flood potential will actually occur.
Also, you will never know the flood hazards as well as your local agencies...and
you need to be connected with them in partnership in order to be successful.
When you start considering other water resources management decisions
covering hydro-power, navigation, water supply, irrigation--it becomes
clear how extremely valuable our water resources are and how managers
use your forecasts for so many things besides flood decisions. When you
are thinking drought-to-flood, AHPS has the potential to more than double
its benefit.
What I like to think about when I think about projects like AHPS is the
potential for residual benefits. You are going to depend on "others" for
a lot of the data that goes into the AHPS product. You are going to have
opportunities to get "outside your box" to educate, partner and work closely
with the media. We all are going to do it together.
What it really comes down to is that there are not a whole lot Jim Whites
[Emergency Manager Harris County, TX] can do to protect individuals
from flooding in Harris County. I mean, he can warn them but if those
individuals don't make good decisions on their own to protect themselves,
Jim has limited capability. He can't go and lift them out of their houses.
They [people at risk] have got to have a plan for their own.
You've got an opportunity with projects like this [AHPS] and
the Internet [as a delivery tool] to encourage self help and
empower people to make good safety decisions.
There are many new ways to use the Internet. I don't think the Weather
Service has really grabbed on to this thing [Internet] yet. It
really has great potential and we haven't seen it fully developed in the
area of hydrology, particularly with local data. I'm trying to encourage
you guys to think along those terms. Where we are moving to with GIS today
gives us the ability to see individual houses. More importantly, the data
behind the picture of a floodplain gives us a ton of information.
Think in terms of the product you [National Weather Service]
put out, when it comes to watches and warnings particularly. If you could
be so specific in a community to identify affected subdivisions--think
of the potential of these kinds of GIS applications have down the road.
The systems capable of this exist today and many communities already have
these in place. With locals bringing this capability to the National Weather
Service--this is clearly a partnering effort worth pursuing. I don't think
you [the National Weather Service] are going to be able to pay
for it [GIS] yourselves. But, if you work with the local governments
who are paying for it and have other needs for it, you will have your
utility implemented through your partnership with those local officials.
In conclusion, I'd like to leave you with one final user perspective.
I take you back to 1993 when the upper Mississippi River basin flooded.
Back in 1993, the National Weather Service went to people and asked, "What
do you need? We are from the federal government and we are here to help.
What can we do to make your job better?" They told them, "We just need
the 'stick." They [the local emergency managers] knew
they needed data, but the federal government being who they are were much
wiser and knew they could do better than that. Now today we have those
same emergency managers shown here with a laptop computers and a wireless
Internet connection. These guys are all using the Internet now and they
are looking at weather products and they are making the same kind of decisions
in 2002 that they did in 1993. Now we are starting to learn how to ask
a different kind of question. The local guys pretty much knew what they
needed. Now the better question to ask these folks is, "What decisions
do you make?" Well, they still make the same decisions. They look at the
"stick" and know what they have to do. As we continue to grown with our
use of technology, let's keep this picture in mind.
If we make a concerted effort to think "outside our box" and ask people
like Jim White, "what decisions do you make" we are going to be in a better
position to provide a tool to help with that decision, or at least work
together to develop a tool that helps us all. Thank you.
