Climate Connection

 
Insufficient Rainfall  
southeast 
Lack of rainfall can lead to short and long-term drought conditions across the region. Over the past few decades, there has been a downward trend in rainfall during the summer months. Most climate models simulate that the decrease in summer rainfall may continue into the future. Additionally, the annual mean precipitation is expected to decrease across the western portion of the Southeast.
