Alex’s Aftermath Gene Norman Chief Meteorologist KHOU-TV Houston, TX National Flood Workshop Oct. 25, 2010

Alex’s Aftermath Timeline Meteorological Conditions Coverage and Technology Lessons Learned

Round 1 – July 1, 2010 Moisture surges from Alex are trapped by stalled front along the coast Storms move inland on persistent southeast winds created by pressure gradient Training storms develop over parts of Brazoria County

Sweeny, TX July 1, 2010

Sweeny, TX July 1, 2010

Sweeny, TX July 1, 2010

Round 2 – July 2, 2010 A left-over moisture axis from the previous day is the genesis for new storms This time the training develops right over the heart of Houston

Coverage Approach Pre-empted programming and went on air at 3:30 pm Monitored rainfall through WeatherBug sensor sites and HC Flood Control site

Coverage Approach Communicated via twitter and NWS Chat Trolled Traffic Cameras To Find Flooded Locations

Lessons Learned Never Take A Land-falling Storm For Granted Develop A Way To More Clearly Illustrate Flood Threat Locations To Viewers
