Hurricane Dorian: Still a flood risk, no matter where it goes.
Leading up to this Labor Day holiday weekend, there has been much discussion and concern over the location of landfall of Hurricane Dorian. Early models had predicted it might slam into the east coast of Florida, causing severe damage from high winds and flooding of various forms. The most recent NOAA National Hurricane Center prediction is a bit uncertain as to the exact location and time of landfall on the US east coast. However, the Bahamas are being hit now (2:PM Eastern). The storm packs 185 MPH winds at its center. The Bahamas don’t have much elevation, so the damage from storm surge and flooding could be severe.
Whereever Dorian goes however, flooding potential is very high for most of Eastern Florida, and ultimately even Georgia, the Carolina, and possibly points north. While it is too late to plan for Dorian, this event raises yet again the issue of smart planning for future flooding events. With all the accurate data sources and excellent GIS tools available now, people can do much better planning and take action to better protect their homes, businesses, and properties.
Predicting and Mapping Flood Risk
“But how do we know what to do and where to do it?” you ask. Well, for many years FEMA the Federal
Emergency Management Agency has maintained a series of flood risk maps for much
of the United States. While the science
behind the FEMA maps is good, they are almost always well out of date, at a
geographic scale that is too course for property level decision making, and
lack consideration of several important factors that need to be considered in
assessing flood risk. Since FEMA maps were initiated, we have much more data
and a far greater understanding of factors such as storm surge, global warming,
and sea level rise. For property owners,
businesses, and local governments to make important improvements to their
flooding preparedness, they need much more detailed and especially more timely
information based on the best science available. FEMA maps just don’t do it for
modern flood risk assessment.
If you are a GIS user, there are some tools to help you in
this area. The NOAA National Hurricane
Center has GIS data available for download, as do many local city, county, and
state governments. With knowledge of the
science of flood prediction, good GIS training and experience, and timely data;
one can piece together some good hazard maps.
Still, the time and resources needed, the search for data needed at a
local level, and the lack of integrated models, etc., make the production of
usable GIS based Flood risk products nearly impossible, at least when faced
with time sensitive situations, and a variety of data sources and local
