Tropical Weather Discussion and Preparedness

Wednesday, August 5th, 2009

Georgia has many types of natural disasters including hurricanes, tornadoes, severe storms, wildfires and floods.  It’s that time of year again that we need to keep an eye on the tropics in order to accurately forecast and anticipate affects to our weather here. NOAA forecasters say a near-normal Atlantic hurricane season is most likely this year. However, as with any season, the need to prepare for the possibility of a storm striking near you is essential. 

 

In August 2005 a record 18 tornadoes struck in Bartow, Carroll, Fannin, Forsyth, Hall, Haralson, Heard, Jackson, Oconee, Paulding, Polk, Taylor, Lumpkin, Peach, Spalding, Walton and White counties when the remnants of Hurricane Katrina passed through the state. One person was killed, six people were injured, and numerous homes and businesses were destroyed. Georgia also became the destination of more than 100,000 evacuees from the Gulf States, requiring several state agencies to implement a range of assistance initiatives.  September of 1999 a record 70 percent of coastal residents evacuated in the face of Hurricane Floyd. Fortunately, Floyd did not come ashore in Georgia, but I-16 was so clogged that distances normally covered in an hour took five hours or more to travel. Georgia shelters housed 35,000 people and 130,000 animals. 

 

In its initial outlook for the 2009 Atlantic hurricane season, which runs from June through November, NOAA’s National Weather Service Climate Prediction Center calls for a 50 percent probability of a near-normal season, a 25 percent probability of an above-normal season and a 25 percent probability of a below-normal season. Global weather patterns are imposing a greater uncertainty in the 2009 hurricane season outlook than in recent years. Forecasters say there is a 70 percent chance of having nine to 14 named storms, of which four to seven could become hurricanes, including one to three major hurricanes (Category 3, 4 or 5).
