Midwest Spring Flood,
April 2008
In
the Spring of 2008, portions of Texas, Oklahoma, Arkansas, Missouri, Illinois,
Indiana, Kentucky, Ohio, and Wisconsin experienced two to three times the
normal precipitation. In some cases, rainfall intensity was extreme,
with 48-hr precipitation totals on March 18-19 approaching or exceeding the
magnitude of a 1000-year event in southeastern Missouri and southern Illinois.
The resultant flooding was widespread and catastrophic. In Missouri, record
flooding occurred on the Black, Gasconade, James and Meramec Rivers. Record
flooding also impacted locations on the Spring River in Hardy, Arkansas, and the
Patoka River in Indiana. Following the March 18-19 deluge, major flooding
affected more than 20 rivers, with almost 400 NWS river forecast points experiencing
flooding. From February to April 2008, the Advanced Hydrologic Prediction Service
(AHPS) web pages was “hit” about a quarter of a billion times.
Throughout these months, communication with NWS partners in the emergency management
community and the general public was vital. In addition, NWS offices also had
to deal with repeated outbreaks of severe weather. Extended hours of operation
were common at the responsible River Forecast Centers. NWS staff made a concerted
effort to provide informal notices to the emergency managers – before public
products were issued – a week or more before major flooding.
The outstanding level of service was possible because of collaboration throughout
the NWS, from the River Forecast Centers, and Weather Forecast Offices to the National
Center for Environmental Protection’s Hydrometeorological Prediction Center
and Climate Prediction Center. It took the work of the entire NWS team to fulfill
its mission.
Steve Bays, a Service Hydrologist in Little Rock, was in the “eye of the storm.” For
more than a month, Steve had only had 2 days away from the office. And his
offices days were usually much longer than 8 hours. Rivers
that pass through Little Rock’s Hydrologic Service Area saw some of the worst
flooding during the latter part of March and into April, with many forecast locations
on the Black and White Rivers experiencing major flooding. In addition to leading
the efforts of the staff at Little Rock in providing flood forecasts and warnings,
Steve spent countless hours conducting local and national media interviews and ensuring
that key partners in the emergency management community had the information they
needed to prepare for and respond to flooding.
He personally contacted Mayor Nina Thornton of Hardy, AR, on the morning of March
17 to inform her that the Spring River could crest higher than the record-setting
level of the September 2006 event. This communication occurred 24 hours before
the heavy rainfall began. As it turned out, the March 19 flood crest was 6
feet higher than the September 2006 event, and yet no one was killed. Afterwards,
the mayor let Steve know that his phone call saved lives. Other property owners
expressed their appreciation for Steve’s early warning that allowed them to
move their property out of harm’s way.
